Technical Field

The invention relates to a valve, comprising: an inlet device having at least one inlet opening and at least one outlet opening; a closing device for opening and closing the at least one access opening; and an operating device for operating the closing device.

Background

The valve is designed to control fluid flow. Fluid passes through the inlet opening with the valve open and is discharged from the valve through the discharge opening. The closing means is used to close the access opening. With the valve closed, the inlet opening is closed by the closing means. The fluid cannot be discharged from the valve.

Valves are used in a variety of products and applications. The invention is directed in particular to the field of hygiene. These valves can be used, for example, in fittings (Armatur). Other application possibilities, for example in domestic appliances such as washing machines or washing machines, can also be envisaged. Industrial applications are also feasible. In principle, the invention can be used wherever it is necessary to control the fluid flow. The fluid is in particular water or a liquid.

A valve of this type is known from DE4238671a1, which is designed as a single-rod mixing fitting. The actuating device is designed as a lever, which is mounted pivotably in the housing. In the housing, the lever engages in a closing device which controls the water flow of the hot and cold water openings. Depending on which direction the lever is pivoted in, more or less water passes through the cold water opening and the hot water opening, so that the temperature at which the water is discharged from the discharge opening of the valve can be controlled via the inclination of the lever.

A similar construction is known from DE202012100687U1, in which a pivotable lever is likewise used as an actuating device.

In EP2971387B1, the actuating device is also mounted pivotably in the valve housing. By pivoting the actuating device, the closing device is moved in the axial direction, so that the inlet opening of the valve is closed or opened. The known valve is used as a stop valve for a hand-held shower which is connected to the water supply via a hose. The actuating device is also designed as a holder for the hand shower. If the hand shower is in the holder, the water supply is closed. If the hand shower is removed from the holder, the actuating device is pivoted into the open position due to the pretensioning force of the spring. In the open position, the valve is open and the hand shower is supplied with water. Such hand-held showers are also known as bidet nozzles.

Disclosure of Invention

The invention is based on the object of providing a valve with an alternative operating mode.

To this end, the invention proposes a valve having: an intake device having at least one intake opening and at least one discharge opening; a closing device for opening and closing the at least one inlet opening and/or the outlet opening; an actuating device for actuating the closing device, characterized in that the actuating device is guided in the housing in an axially movable manner in a first direction; and the valve further has a coupling element interconnecting the operating device and the closing device such that axial movement of the operating device causes movement of the closing device in a second direction different from the first direction.

The invention also relates to a fitting, in particular a sanitary fitting, characterized in that the fitting has a valve according to the invention.

According to the invention, the actuating device is guided in the housing in an axially movable manner in the first direction. Such an axial guidance of the actuating device is particularly space-saving with respect to conventional pivotable solutions. According to the invention, a coupling element is also provided, which is coupled to the actuating device and to the closing device, wherein an axial movement of the actuating device causes a movement of the closing device in a second direction, which is different from the first direction. The actuating device thus drives the coupling element, which itself drives the closing device. The structure according to the invention is compact, simple to construct and functionally reliable.

Preferably, the closing means causes the opening and closing of the at least one access opening. Alternatively or additionally, the closing device can also cause the opening and closing of the discharge opening.

An access opening is understood within the scope of the present invention as an access channel which is formed by an access device. But equally within the scope of the invention an access opening is understood to be an opening in a plane adjoining the closing means. The outlet opening is understood within the scope of the invention as an outlet channel which is formed by the inlet device. Within the scope of the invention, however, the outlet opening is also understood to be an opening in a plane adjoining the closure device.

The invention can be used in a variety of applications, for example as a valve for sanitary fittings or as a valve for household appliances, such as washing machines or washing machines. Industrial applications can also be envisaged.

Another advantage of the valve according to the invention is the small dead space in which fluid remains when the valve is closed. From the prior art, so-called pilot valves are known, in which a diaphragm is used as a closing device and, to equalize the pressure, the water reaches behind the diaphragm on the flow side. This water remains at least partially behind the membrane even with the valve open, with the risk of germs propagating. In contrast, the valve according to the invention has significant advantages: no fluid stagnation occurs with the valve open. As the fluid is dragged along by the flow with the valve open. This also results in hygiene advantages.

Preferably, the axial movement of said manoeuvring means causes a translational movement of the closing means. The closing device is therefore not rotated during its movement, but is mounted in a housing in a translatorily movable manner, advantageously in a one-dimensional translatorily movable manner. Such a bearing is simple and has a high service life.

An advantageous embodiment of the invention is characterized in that the direction of movement of the actuating device and the direction of movement of the closing device are oriented orthogonally to one another. In particular, it can be provided that the actuating device is guided in a first guide and the closing device is guided in a second guide, wherein the first guide and the second guide are oriented orthogonally to one another. The orthogonal arrangement of the directions of movement provides a completely novel kinematic solution that allows a simple and durable construction of the valve.

In a further development of the invention, it is proposed that the closing device slides on the access device when the actuating device is actuated. The inlet device expediently forms an inlet opening and/or an outlet opening, so that said inlet opening and/or outlet opening can be closed simply by a sliding movement. Such a closure is considered to be very reliable. Furthermore, this construction is durable, since the sealing region is kept free of deposits, in particular of calcareous deposits, by the sliding movement.

According to the invention, the inlet device has at least one inlet opening and at least one outlet opening. Preferably, the closing means and the inlet means form a passage in the open position of the valve, which passage connects the at least one inlet opening and the at least one outlet opening with each other. When the valve is open, fluid (which is preferably referred to as liquid) can pass through the inlet opening into the passage and out the outlet opening. Thereby, the flow path through the valve can be kept very short and the structure as a whole can be kept very simple. Advantageously, the closing means closes the at least one access opening of the access means in the closed position of the valve.

The coupling element is connected to the actuating device and to the closing device. A particularly kinematically advantageous embodiment is characterized in that the coupling element is connected pivotably to the actuating device. The pivotable coupling element advantageously conveys the closing device into its open or closed position as soon as the actuating device is moved in the axial direction. In this way, a particularly flat design can be achieved. This applies in particular when the pivot axis of the coupling element is configured orthogonally to the movement axis of the actuating device (as is considered advantageous per se). In addition or alternatively, the coupling element can be connected pivotably to the closing device. Preferably, the pivot axis of the closing means extends parallel to the pivot axis of the operating means. In this connection it is pointed out that the pivot axis of the closing means does not necessarily have to be formed by the closing means. More precisely, the closing device can also accommodate the coupling element in such a way that the coupling element is pivotable. The same applies to the operating device.

As already mentioned above, it is advantageous if the closing means can slide on the access means. Thereby, both devices are subjected to a certain load. In order to minimize wear, it is proposed that the access device be made of a ceramic material. Ceramic materials have other advantages in addition to good wear properties. The ceramic material can be produced in particular with a very high degree of accuracy. Furthermore, the ceramic material is resistant to corrosion media, such as acids or the like. This allows the valve to be used in a wide range of industrial applications. Additionally or alternatively, the closing device can also be made of a ceramic material. If the two components that can be moved on each other are made of a ceramic material, a highly wear-resistant material pairing results. Thereby resulting in a high service life of the valve.

Preferably, the closing device has a slide which slides on the access device when the actuating device is actuated. Preferably, the slider is made of a ceramic material having the advantages described above. The advantage of a multi-part closure is that each part can be adapted to its primary purpose of use. The sliding element is made of a wear-resistant, in particular abrasion-resistant, material, for example a ceramic material. The upper member may be mounted to the slide. Additionally or alternatively, the upper part may be connected with the slide. The connection is preferably releasable. For example, a form-locking connection.

The upper part is preferably not in contact with the fluid. The upper part is preferably made of another material, for example plastic. This achieves that: the upper part can be produced as an injection-molded part and can therefore be produced cost-effectively. Furthermore, the multi-piece construction of the closing device allows for an advantageous assembly of the valve.

Preferably, the upper part and the slide are in engagement with each other. If the coupling element moves the closing device, the slider and the upper part move together.

It is considered to be particularly preferred if the coupling element is supported between the upper part and the slide. The coupling element can thereby advantageously be held between the upper part and the slider. At the same time, the bearing allows a movement of the coupling element, in particular a pivoting movement of the coupling element.

An advantageous embodiment of the invention is characterized in that the valve has a linear guide in which the closing means is guided in a linearly movable manner. This ensures a always correct positioning of the closing device relative to the access device, which is important in particular for the closed position of the valve. A simple and effective linear guide can be realized by: the linear guide has at least one guide rail which interacts with at least one sliding surface of the closing device. The sliding surface slides on the guide rail when the closing means moves. In this case, the at least one sliding surface bears against the guide rail. Preferably, the at least one guide rail is configured linearly.

Advantageously, the linear guide has two guide rails, wherein each guide rail interacts with an associated sliding surface of the closing device. The guide rails are formed, for example, as inner surfaces which each bear against an outwardly directed sliding surface. Here, the linear guide may overlap the closing device.

It has been said above that advantageously the valve allows a simple assembly. In this connection, it is proposed that the linear guide is accommodated in the housing as a separate component, preferably a centering means is provided between the housing and the linear guide for the orientation of the linear guide in the housing. The centering means can be designed as a groove or a tongue which interacts with a tongue or groove formed on the inside of the housing. Centering of the linear guide is also advantageous if the linear guide defines the direction of movement of the closing means. Thereby, a high reliability of the closing and opening action of the valve can be ensured.

In the case of operating a valve, different mechanisms are considered. If the operator is manipulated, the operator remains in either the closed position or the open position. If the actuating device is pressed, for example, the valve opens and remains in the open position until the actuating device is actuated again. Alternatively, the valve is in the open position and the actuating device always returns into this open position again after it has been actuated. In other words, when the actuating device remains undepressed, it is in an initial position in which the valve is in the open position. This mechanical construction opens up a completely novel application possibility as explained in more detail in connection with the description of the figures.

An advantageous embodiment of the invention is characterized in that the actuating device is biased into the open position, wherein the actuating device is in the open position of the valve when the actuating device is not actuated.

This mechanical construction can preferably be achieved by: the linear guide forms a bearing for a pretensioning means which is supported on the linear guide and pretensions the actuating device into the open position of the valve. The pretensioning means may be a spring.

Alternatively, the actuating device has a magnet, which is preferably arranged at the free end of the actuating device. The magnet can interact with a mating magnet in such a way that the mating magnet pulls the actuating device out of the housing. The mating magnet is, for example, associated with a hand shower. As soon as the hand shower is removed from the housing, the magnet and thus also the actuating device are (further) pulled out of the housing.

In valves of this type, it is known to provide the valve with a housing. The valve can then be installed as a cartridge, for example, in a sanitary device, such as a fitting. Preferably, the actuating device is designed as a push button which is supported on the inside of the housing in the open position or in the closed position of the valve. For this purpose, the push button advantageously has a shoulder. The shoulder serves as a stop for the push button, which is expediently under pretension.

In a further development of the invention, it is proposed that the housing has a housing lower part and a housing upper part connected to the housing lower part, wherein at least one inlet and at least one outlet are formed in the housing lower part, which are in fluid communication with the at least one inlet opening and the at least one outlet opening of the inlet device. Thus, fluid enters the valve through the inlet portion into the inlet opening and exits the valve through the outlet opening and the outlet portion of the housing. Preferably, the actuating device is guided in the housing upper part in the axial direction. The closing device and the coupling element are advantageously arranged in the housing. A compact, universally usable bobbin is obtained.

The invention allows for a variety of embodiments. The valve can be in the closed position or in the open position if the actuating device is actuated, i.e. pressed. For this purpose, the closing device can be adapted accordingly. Embodiments are possible in which the actuating device is pressed into its initial position by a prestressing means. The initial position may relate to an open position or a closed position. If the actuating device is in its depressed position and is then no longer actuated, the pretensioning means can press the actuating device into its initial position again. Alternatively, embodiments are provided within the scope of the invention in which the actuating device can assume two end positions, in which the actuating device remains. These two end positions may relate to the open or closed position of the valve. It is proposed, for example, that the valve can be opened and closed according to the principle of a ballpoint pen. The principle of ballpoint pens is known per se. Incorporating the valve according to the invention allows: the operating device occupies two stable end positions. An advantageous embodiment is characterized in that the housing upper part has on its inner side a guide for a latching element of the actuating device and a first stop against which the actuating device rests in the first end position. In this end position, the actuating device is preferably pressed into the housing against the pretensioning force of the pretensioning means. Here, the valve may be open or closed. By forming the guide and the stop in the housing upper part, a compact and simple construction is obtained. Preferably, the guide has a second stop on the end side, against which the actuating device rests in the second end position. In this end position, the actuating device is preferably in its initial position.

Detailed Description

Fig. 1 shows a first embodiment of a valve according to the invention. The valve has an inlet device 1 with an inlet opening 2 and an outlet opening 3. Within the scope of the invention, it is also possible to provide a plurality of inlet openings 2 and/or a plurality of outlet openings 3. The access device 1 is preferably made of a ceramic material. The inlet device is thus resistant to corrosion media and is also wear-resistant.

The access device 1 interacts with a closing device 4 which can slide on the access device 1. The closing device 4 has a passage 5 which, in the illustrated open position of the valve, connects the inlet opening 2 with the outlet opening 3. Thereby, a fluid, for example a liquid, in particular water, can flow through the inlet opening 2 and out of the outlet opening 3, as this is indicated by the arrow P1. It is pointed out at this point that in the embodiment shown, the closing means 4 form a channel 5. In principle, it is advantageous that the closing means 4 and the inlet means 1 form a channel 5 which interconnects the at least one inlet opening 2 and the at least one outlet opening 3.

The valve according to the invention can be actuated by means of an actuating device 6. The spring 7 holds the operating device 6 in the open position of the valve. The actuating device 6 is guided in the housing 8 in an axially displaceable manner and can be moved against the biasing force of the spring 7 in the direction of arrow P2.

The coupling element 9 is coupled to the actuating device 6. For this purpose, the actuating device 6 has a pivot axis 10, on which the coupling element 9 is pivotably supported. Coupling element 9 has a free end 11, with which coupling element 9 is pivotably supported on closing device 4.

The closing device 4 is in the present case designed in multiple parts and has a slide 12 and an upper part 13, between which the free end 11 of the coupling element 9 is pivotably received. The slide 12 can be made of a different material than the upper part 13, in particular of a ceramic material. If the access device 1 is also made of a ceramic material, this material pair forms a wear-resistant and therefore durable interface between the access device 1 and the closing device 4. The upper part 13 can be made of plastic, for example, because it is not loaded as strongly as the slide 12. Preferably, the slide 12 and the upper part 13 are in engagement with each other, as explained in more detail in connection with fig. 3.

The housing 8 has a housing upper part 14 and a housing lower part 15, which are in engagement with each other. For this purpose, latching projections 16 are arranged on the housing upper part, which engage in corresponding recesses 17 of the housing lower part 15 (see fig. 3).

The actuating device 6 is guided in an axially movable manner in the housing 8, in particular in the housing upper part 14. As already explained above, the actuating device 6 is prestressed into its initial position (i.e. the open position of the valve). In this position, the actuating device 6 is supported by means of the shoulder 18 on the inner side 19 of the housing upper part 14. Preferably, the actuating device 6 passes through an opening 20 of the housing upper part 14 in the open position of the valve and projects with its free end 21 out of the housing 8.

The linear guide is designated with reference numeral 22. The linear guide may have multiple tasks. This linear guide ensures on the one hand: the closing means 4 is guided linearly in the housing 8, as is also explained in more detail in connection with fig. 3. On the other hand, as can be seen in particular from fig. 1 and 2, the linear guide 22 also has a spring guide 23 in the exemplary embodiment shown. The spring guide serves to guide the spring 7 and to support it, but preferably also (additionally) to guide the actuating device 6. In principle, it is considered to be advantageous for the linear guide 22 to be held fixedly in the housing 8.

The access device 1 is held fixed in the housing lower part 15 and is sealed off from the housing lower part 15. In particular, the inlet opening 2 and the outlet opening 3 are sealed off from the housing lower part 15 by means of a sealing ring 24.

The valve according to the invention can be configured as a cartridge. The bobbin itself can be inserted into a sanitary fitting, for example. For this purpose, the housing lower part 15 has a circumferential sealing ring 24, which seals the housing 8 against the fitting. A sealing ring 24 may also be arranged on the housing upper part 14.

Fig. 1 shows a first embodiment of a valve according to the invention in the open position of the valve.

Fig. 2 shows the first embodiment in the closed position of the valve. Reference is now made to fig. 2.

In fig. 2, the actuating device 6 is pressed against the force of the spring 7. In this position, the spring guide 23 forms a stop for the actuating device 6. When the actuating device 6 is moved from the open position according to fig. 1 into the closed position according to fig. 2, the pivot axis 10 also moves together with the actuating device 6. In this case, the coupling element 9 is pivoted and, by means of its free end 11, moves the closing device 4 into the closed position (i.e. to the right in fig. 2). At this point, the closing device 4 slides on the access device 1. In the closed position, the closing means 4 closes the access opening 2, as this is indicated by arrow P3. Thus, fluid can no longer enter the inlet opening 2 in the closed position. In the closed position, the valve is closed.

It is pointed out at this point that the first embodiment is designed such that the valve is always closed as long as the actuating device is held in the closed position. If no more force is applied to the actuating device 6, the actuating device 6 is moved into the open position due to the pretensioning force generated by the spring force. In the open position, the valve is open, see fig. 1.

Fig. 3 shows an exploded view of the first embodiment. The foregoing has set forth: the housing upper part 14 preferably has a latching projection 16 which can engage in a recess 17 of the housing lower part 15. Preferably, the housing upper part 14 and the housing lower part 15 are releasably connected to each other.

The actuating device 6 has two receptacles 25 through which the pivot axis 10 is plugged. The coupling element 9 is pivotably supported on a pivot shaft 10.

Within the scope of the inventive concept, it is considered to be advantageous if the actuating device 6 is guided axially in the housing 8 and the closing device 4 advantageously executes a translatory one-dimensional movement when the actuating device 6 is moved. In order to orient all the components correctly relative to one another, the handling device 6 and/or the linear guide 22 preferably have centering means, which may be configured as a groove 26, as this is shown in fig. 3. Thereby, a correct positioning of the handling device 6 and the linear guide 22 in the housing 8 and thus a correct orientation of the direction of movement of the closing means 4 is ensured.

Preferably, the linear guide 22 forms a linear guide for the closing device 4. For this purpose, the linear guide 22 advantageously has at least one guide rail 27, preferably two guide rails 27, which interact with a corresponding sliding surface 28 of the closing device 4. Currently, the linear guide 22 advantageously overlaps the closing device 4. In the first embodiment, the sliding surface 28 is configured on the upper part 13 of the closing device. The upper part 13 engages with at least one projection 29 into a slot 30 of the slide 12. By guiding the closing device 4 in the linear guide 22 it is ensured that: in the case of actuation of the actuating device 6, the slide 12 executes a defined movement, which is advantageously a linear movement. Thereby it is ensured that: the closing means 4 connect the inlet opening 2 with the outlet opening 3 in the open position and close the inlet opening 2 in the closed position.

The seal which seals the valve according to the invention against the fitting body is designated by the reference numeral 31, as is also explained in more detail in connection with fig. 17 to 19.

Fig. 4 shows a second embodiment of the valve according to the invention. It is noted at this point that within the scope of the description of the present figures, similar components of the valve according to the invention are partially designated by the same reference numerals for reasons of clarity of the hierarchy, even if they have slightly different configurations.

In contrast to the first embodiment, the second embodiment does not have a spring. The restoring force for restoring the actuating device 6 is provided by a magnet 32, which is arranged at the free end 21 of the actuating device. Since no spring is required, the spring guide 23 is also eliminated in the linear guide 22. Otherwise, the second embodiment is basically configured the same as the first embodiment.

The second embodiment is shown in the open position similar to fig. 1. In this open position, the free end 21 of the actuating device 6 protrudes from the housing 8. As soon as the actuating device 6 is moved into the housing 8, the coupling element 9 converts the axial movement of the actuating device 6 into a lateral movement of the closing device 4. Advantageously, the direction of movement of the operating device 6 and the direction of movement of the closing device 4 are oriented orthogonally to each other.

In order to transfer the valve according to the second embodiment from the closed position, like in fig. 2, into the open position, the magnet 32 is pulled out of the housing 8 by means of a second magnet 33 (see fig. 17), as is also explained in more detail in connection with fig. 17 to 19.

Furthermore, as in the case of the first embodiment, an inlet 34 and an outlet 35 are configured in the housing lower part 15, which are in fluid communication with the inlet opening 2 and the outlet opening 3.

Reference is now made to fig. 5 and 6, which show details of the second exemplary embodiment, namely the coupling of the actuating device 6 to the closing device 4 via the coupling element 9, wherein only the upper part 13 of the closing device 4 is shown in the present case.

The actuating device 6 has a pivot axis 10, on which the coupling element 9 is pivotably supported. Coupling element 9 is in engagement with closing device 4 with its other end 11 (see fig. 4). The axial movement of the operating device 6 causes a lateral movement of the closing device 4. As becomes clear from fig. 5 and 6, the coupling element 9 is accommodated between the upper part 13 of the closing device 4 and the slider 12. The coupling element is in particular pivotably supported between the upper part 13 and the slider 12.

Fig. 5 and 6 show a detail of a second exemplary embodiment, in which a magnet 32 is arranged in the actuating device 6. This principle of action corresponds to the first embodiment (without the magnet 32).

Reference is now made to fig. 7 and 8, which illustrate a third embodiment of the present invention. The third exemplary embodiment differs from the first and second exemplary embodiments in that the valve is in its closed position without the actuating device 6 being pressed. In the closed position, the actuating device 6 is preferably biased into its initial position by a spring 7. The closing means 4 close the discharge opening 3 in the closed position according to fig. 7. The channel 5 is arranged above the inlet opening 2 in such a way that fluid cannot pass through the inlet opening 2, as this is indicated by the arrow P5.

In fig. 8, the actuating device 6 is pressed and the valve is in the open position. In the open position, the closing device 4 is arranged relative to the inlet device 1 such that the channel 5 connects the inlet opening 2 with the outlet opening 3. Thereby, fluid may flow through the inlet opening 2 and the outlet opening 3, as this is illustrated by the arrow P6.

Otherwise, the third embodiment corresponds to the first embodiment, to which reference is made to the description of the first embodiment.

Fig. 9 shows a fourth embodiment of the valve according to the invention. The valve is in the closed position in fig. 9. The access opening 2 is closed by a closing device 4. The closing device 4, in contrast to the above-described embodiment, also has a tab 48, which covers the discharge opening 3. Thus, in the closed position, the inlet opening 2 and the outlet opening 3 are closed. Reference is made to the first embodiment for the remaining construction of the valve.

Fig. 10 and 11 show the position of the closing device 4 relative to the access device 1 in a fourth embodiment in a functional diagram. Only the closing device 4, which now has a slide 12 and an upper part 13, and the access device 1, respectively, are shown. Fig. 10 shows the fourth embodiment in the closed position, as shown in fig. 9. In this case, the closing device 4 closes both the inlet opening 2 and the outlet opening 3 by means of the web 48. Fluid cannot enter the inlet opening 2, as this is illustrated by arrow P7. Fig. 11 shows the open position of the valve, in which the passage 5 interconnects the inlet opening 2 and the outlet opening 3, as this is shown by the arrow P8.

Fig. 12 and 13 show another embodiment. According to fig. 12, the discharge opening 3 is closed in the closed position by the closing means 4, as this is illustrated by the arrow P9. In fig. 13, the closing device 4 is in the left end position, in which the passage 5 connects the inlet opening 2 with the outlet opening 3, so that fluid can flow out of the outlet opening 3 through the passage 5 via the inlet opening 2 (arrow P10).

Reference is now made to figures 14 to 16 which illustrate a sixth embodiment of a valve according to the present invention. In this embodiment, the actuating device 6 occupies two stable end positions, namely an open position and a closed position. In the first end position, the actuating device 6 is pressed into the housing upper part 14 (fig. 16) and remains there, and in the second end position, the actuating device 6 is in the initial position, in which it remains (fig. 15).

Within the scope of the description, reference numerals are also used for slightly different components for reasons of better hierarchical clarity.

The sixth embodiment is based on the principle of a ball point pen, which is known per se. By pressing the actuating device 6 once, the actuating device 6 is moved from the position shown in fig. 15a into the position according to fig. 16 a. By pressing again, the actuating device 6 returns again into the position shown in fig. 15 a.

The construction of the valve according to fig. 14 largely corresponds to the first embodiment. In this connection, reference is made to fig. 3, which is a more detailed description of the valve, and fig. 3 likewise shows an exploded view of the valve. Unlike in the case of the first exemplary embodiment, the actuating device 6 is of three-piece design. The actuating device has a base element 49, a latching element 50 and a push button 51. The catch element 50 and the push button 51 are rotatably received on the base element 49. The push button 51 passes through the opening 20 of the housing upper part 14 in the assembled state.

Along its circumference, the latching element 50 has axial rails 52 which can engage in corresponding guides 53 of the housing upper part 14. A stop 54 is also formed on the inner side of the housing upper part 14, against which the rail 52 of the latching element 50 rests in the first end position.

Refer to fig. 15a and 15 b. Fig. 15a shows a partially cut-away view of the sixth exemplary embodiment according to fig. 14, while fig. 15b shows an expanded view of the catch element 50, of the push button 51 and of the housing upper part 14. The actuating device 6 or its keys 51 are in the second end position, i.e. the initial position. In this second end position, the latching element 50 rests with the projection 55 against a stop 56 of the housing upper part 14. Preferably, the stopper portion 56 is arranged on the end portion side of the guide portion 53.

When the push button 51 is pushed into the housing upper part 14, the latching element 50 moves along the guide 53 until the rail 52 comes out of the guide 53. When the push button 51 is unloaded, the rail 52 comes to rest against the stop 54 (first end position), as shown in fig. 16a and 16 b. When the button 51 is pressed again, the rail 52 again reaches the guide 53, until the position according to fig. 15a and 15b is reached.

Accordingly, a sixth embodiment provides a valve having two stable end positions, wherein the valve is in the closed position in one of the end positions and in the open position in the other end position. Whether a closed position or an open position is present depends on the design of the closing means 4.

Fig. 17 to 19 show an application example of the valve according to the present invention. Not only the first embodiment but also the second embodiment may be used here. A second embodiment is shown. Shown is a bidet spray head. Other sanitary and non-sanitary fittings can also be envisaged. The present invention can be used in every place where fluid flow is to be controlled by pressing the manipulating device.

The valve according to the invention is used in a bidet head set. The accessory group has a hand shower 36 with a handle 37 and operating buttons 38. The hand shower is connected to the fitting housing 40 via a hose 39. The valve is inserted into the fitting housing 40. The fitting housing 40 has a water inlet portion 41 that is in flow communication with the inlet portion 34 of the valve. The housing 8 is sealed here with respect to the fitting housing 40 via a seal 31. The same applies to the sealing ring 24.

The housing 8 is inserted into the fitting housing 40 and is fixed in the fitting housing 40 by means of a union nut 42. The actuating device 6 can be passed with its free end 21 through the union nut 42.

In fig. 17, the valve is in the closed position. In the closed position, the access opening 2 is closed by the closing means 4. The hose 39 is not under pressure. The hand shower 36 overlaps the fitting housing 40 with a skirt 43 that retains the hand shower 36 on the fitting housing 40.

As soon as the hand shower 36 is removed from the fitting housing 40 in the direction of arrow P4 (as shown in fig. 18), the second magnet 33 carries the magnet 32 of the actuating device 6 and pulls it out of the housing upper part 14. The closing means 4 is displaced from the closed position into an open position in which the passage 5 connects the inlet opening 2 with the outlet opening 3. The hose 39 supplies water via the water outlet 44 in the open position, so that the hand shower 36 can be operated via the operating button 38.

In fig. 18, the hand held shower 36 and the accessory are also coupled via magnets 32 and 33. In the open position, the hand shower 36 can be removed, as shown in fig. 19. In this position, full water pressure is exerted on the hose 39. When the actuation button 38 is actuated, water is discharged from the opening 45. If the hand shower 36 is plugged onto the fitting housing 40 counter to the direction of movement of the arrow P4, the valve is closed to protect the hose 39. Thus, the valve according to the invention can be used such that it is closed when the hand shower 36 is placed on the accessory housing 40 and is open when the hand shower is removed from the accessory housing 40. A preferably circumferential ridge is designated by reference numeral 46, which interacts with a depression 47 of the hand shower 36. If the hand shower 36 is plugged onto the fitting housing 40, the bulge 46 snaps into the depression 47, so that the hand shower 36 is held on the fitting housing 40.

Fig. 20 and 21 show a seventh embodiment. The seventh embodiment is largely identical in construction to the first embodiment, and thus the same reference numerals are used in this regard and reference is made throughout to the description of the first embodiment even though some of the components are slightly different from one another.

In fig. 20, the seventh exemplary embodiment is shown in the open position and corresponds to fig. 1 in this respect. The important difference with respect to the first exemplary embodiment is that in the first exemplary embodiment, the closing device 4 is moved to the right (see fig. 2) when the actuating device 6 is pressed. In the first exemplary embodiment, the closing device 4 is therefore in the initial position on the left in the open position (fig. 1). In contrast, in the seventh exemplary embodiment, the closing device 4 is in the initial position on the right in the open position (fig. 20). If the actuating device 6 is pressed, the closing device 4 moves to the left into the closed position (fig. 21). The closing direction therefore acts in the seventh embodiment exactly opposite to that in the first embodiment.

Fig. 22 and 23 show an eighth embodiment. The eighth embodiment is largely identical in construction to the third embodiment, so that the same reference numerals are used in this regard and a full reference is made to the description of the third embodiment even though some of the components are slightly different from one another.

In fig. 22, the eighth embodiment is shown in the closed position and corresponds to fig. 7 for this purpose. Here too, fluid cannot pass through the inlet opening 2. The actuating device 6 is in the initial position. The important difference with respect to the third exemplary embodiment is that in the third exemplary embodiment the closing device 4 is moved to the right (see fig. 8) when the actuating device 6 is pressed. In the third exemplary embodiment, the closing device 4 is therefore in the initial position to the left in the closed position (fig. 7). In contrast, in the eighth exemplary embodiment, the closing device 4 is in the initial position on the right in the closed position (fig. 22). If the actuating device 6 is pressed, the closing device 4 is moved to the left into the open position (fig. 23). The closing direction therefore acts in the eighth embodiment exactly opposite to that in the third embodiment.

If orientation or direction statements such as axial, lateral, above or below are used in the present description, these statements relate to an upright valve, wherein the actuating device 6 projects upwards. The axis extends from the top to the bottom.
