Technical Field

The present invention relates to a canister arrangement, in particular a brake fluid reservoir for a hydraulic brake system of a vehicle, the canister arrangement comprising a canister having a canister wall comprising a connection port for mechanically and fluidically connecting the canister to the hydraulic brake system, whereby the connection port comprises an actuatable valve which is closed in its unactuated state and which is open in its actuated state, the valve further comprising an actuator element which projects outwardly from the canister at least in its unactuated state, the actuator element being slidably mounted on the canister wall for actuating the valve.

Background

Tank arrangements of the above-mentioned type are known from the prior art. A common brake fluid reservoir comprises a tank with a connection port designed to connect the tank to a master brake cylinder of a hydraulic brake system of the vehicle. The connection port comprises one or more valves, in particular check valves. One or more check valves ensure that no brake fluid unintentionally leaves the canister when the fluid reservoir is removed from the master brake cylinder. Since the valve typically comprises an actuator element that protrudes outwardly from the tank, such that the valve can be actuated by the master brake cylinder by applying a force (e.g. hydraulic or mechanical pressure) on the actuator element at an appropriate time, this pushes the actuator element into the tank to open the valve such that brake fluid can flow into the tank.

Disclosure of Invention

An advantage of the invention is that unintentional opening of the valve and intentional loss of brake fluid is inhibited by a cost-effective and reliable design of the canister. According to the invention, at least one safety wall is provided which projects from the tank wall at least as far as the actuator element in the unactuated state in the vicinity of the actuator element. Due to this arrangement it is more difficult to reach the actuator element and the safety wall, which safely prohibits the actuation of the actuator element by placing the tank on a table or floor, will stand on the floor and thus hinder the floor from pushing the actuator element into the tank.

According to a preferred embodiment of the invention, two safety walls protrude from the tank wall, such that the connection port (in particular the at least one actuator element) is arranged between these safety walls. It is therefore more difficult to reach the actuator element between the safety walls, so that the possibility of unintentional actuation of the valve is further reduced. Preferably, the two safety walls are arranged parallel to each other and equally project from the tank wall.

According to a further embodiment of the invention, the respective side wall preferably protrudes further from the tank wall than the actuator element in its unactuated state, such that the respective side wall exceeds the actuator element. This ensures a safety distance defined by the safety wall or walls and makes it increasingly difficult to actuate the valve (in particular unintentionally) by using the actuator element.

It is particularly preferred that the actuator element is slidably mounted on or in the tank wall such that it can be pushed into the tank for actuating the valve. Thus, the valve can be easily actuated when the tank device is correctly assembled on, for example, the master brake cylinder.

Provision is preferably made for the respective safety wall to be designed in one piece with the tank wall. The integral design allows for a cost-effective manufacturing of the tank arrangement and it provides a reliable and robust safety against unintentional opening of the valve.

According to an alternative embodiment, the safety wall is preferably attached to the tank wall as a separate element (in particular in a detachable manner). The respective safety wall is therefore designed as a separate element which is attached (in particular detachably attached) to the tank wall. This design as a separate element allows a cost-effective manufacturing of the safety wall itself and it allows an easy adjustment of the tank arrangement for different tasks and/or space requirements within the vehicle.

According to a further preferred refinement, the respective side wall comprises a curved end portion such that it at least partially surrounds the connection port. The bent end ensures that the connection port is secured from almost all sides.

The actuator element is preferably slidably mounted in a guide dome which also projects from the tank wall. In this configuration, the actuator element is slidably arranged within and protrudes from the guide dome, whereby the guide dome is protected by the at least one side wall as described before. The advantage of the guide dome is that the valve is stably and reliably movably arranged on/in the tank wall of the tank.

Preferably, the connection port comprises at least two valves and/or at least two actuator elements protruding from the tank wall. It is particularly advantageous if the tank arrangement (in particular the brake fluid reservoir) is designed to be attached to a tandem master cylinder comprising two hydraulic chambers. In this case, each valve is designed to be connected to one of the hydraulic chambers.

Furthermore, it is particularly preferred that a respective safety wall is assigned to both actuator elements or that at least one safety wall is assigned to each actuator element. Thus, each actuator element is provided with its own at least one safety wall, or available actuator elements are provided with a common safety wall or two common safety walls, as previously described.

Detailed Description

Fig. 1 shows a perspective view of an advantageous tank arrangement 1, which tank arrangement 1 comprises a tank 2 for storing, supplying and receiving a fluid. According to the exemplary embodiment described herein, the tank 2 is designed as a brake fluid reservoir for brake fluid in a hydraulic brake system of a vehicle. The tank arrangement 1 further comprises a detachable cover 3 on the upper side, which detachable cover 3 can be detached, so that brake fluid can be filled manually into the tank 2. The tank arrangement 1 further comprises a connection port 4, which connection port 4 is arranged on the tank 2 and is designed to mechanically and fluidically attach/connect the tank 2 to a brake system (in particular a master brake cylinder, for example a tandem master brake cylinder of a brake system). The connection port 4 is arranged on the underside of the tank 2 such that the lid 3 and the connection port 4 are arranged on the tank 2 on opposite ends.

Fig. 2 shows a detailed view of the connection port 4 on the tank 2. The connection port comprises two valves 5, 6, which valves 5, 6 are arranged in the tank 2 on a lower tank wall 7. Each valve 5, 6 comprises an actuator element 8, 9, which actuator element 8, 9 protrudes from the tank wall 7 to the outside of the tank 2. The actuator elements 8, 9 are designed as actuator rods which are arranged substantially perpendicular to the extension of the tank wall 7.

The actuator elements 8, 9 are slidably arranged within conical guide domes 10, 11 also protruding from the tank wall 7. According to a particularly preferred embodiment, the valves 5, 6 are arranged within the guide domes 10, 11. The actuator elements 8, 9 protrude from the free ends of the guide domes 10, 11 at least in their unactuated state, as shown in fig. 2. In the unactuated state, the valves 5, 6 are closed such that the fluid connection into the tank 2 is sealed such that no fluid from the tank 2 can leave the tank 2 through the connection port 4. By pushing the actuator element 8, 9 inwards, which means into the tank 2 or into the guide domes 10, 11, the respective valve 5, 6 is opened and brake fluid can leave the tank 2 or flow into the tank 2.

In order to protect the connection port 4 from unintentional actuation of the valves 5, 6, safety walls 12, 13 are provided. The safety walls 12, 13 each project from the tank wall 7 substantially parallel to the extension of the actuator elements 8, 9 and their extension is at least as far as the actuator elements 8, 9 in their unactuated state. The safety walls 12, 13 are arranged such that two actuator elements 8, 9 are arranged between the safety walls 12, 13. According to the present example, both safety walls 12, 13 comprise a curved shape over their longitudinal extent, so that the connection port 4 is almost completely surrounded by the safety walls 12, 13.

Since the safety walls 12, 13 protrude at least far from the tank wall 7 and the actuator elements 8, 9 in their unactuated state, it is ensured that the actuator elements 8, 9 are not pushed by mistake into the tank 2 when the tank arrangement 1 is placed on a floor, a table or the like. Also, when handling (or for carrying) the canister arrangement 1, the safety walls 12, 13 ensure that it is unlikely that a finger of a person handling the canister arrangement, for example, will push the actuator elements 8, 9 and thus actuate the valves 5, 6.

The safety walls 12, 13 thus ensure that unintentional opening of the tank 2 at the connection port 4 is inhibited.

Fig. 3 displaces the tank arrangement 1 in an enlarged side view of the connection port 4. The guide domes 10, 11 and the actuator elements 8, 9 behind the safety wall 12 are drawn with dashed lines to show their arrangement behind the side walls. The side walls 12, 13 preferably extend or protrude further from the tank wall 7 than the actuator element in its unactuated state, so that a safety distance between the side walls 12, 13 and the ends of the actuator element 8, 9 is ensured, which makes an unintentional actuation of the valve 5, 6 more difficult or impossible.

The safety walls 12, 13 are preferably designed as separate elements, which are attached to the tank wall 7, in particular to the connection port 4. Optionally, the safety walls 12, 13 are detachably arranged on the tank 2 such that they can be interchanged for different sets of safety walls 12, 13, these safety walls 12, 13 protruding even further from the tank wall 7, for example. In this way, the tank arrangement 1 can easily be adjusted to suit different requirements or circumstances. Alternatively, the safety walls 12, 13 are designed in one piece with the tank 2 or the connection port 4.
