Technical Field
The present invention relates to a filter cartridge for a fluid filter group. Furthermore, the present invention also relates to a base assembly comprised in said fluid filter group adapted to engage said filter cartridge. In addition, the invention also relates to a fluid filter group, an assembling method and a disassembling method thereof.
The invention finds its preferred application in the automotive field. In particular, the background to which the invention is directed is, in fact, fluid (particularly with reference to the fluids, liquids or gases required for the operation of motor vehicles) filtration systems. In other words, the fluid filter group according to the invention and the components comprising it can be applied in air lines, oil lines, fuel lines and/or water (or aqueous solution) lines comprised in a vehicle.
Systems for fluid filtration in automotive applications are known in the art.
Such known filtration systems include one (or more) filter cartridges integrally connected to a base assembly that is fluidly connected to a respective fluid circulation system. The filter set and base assembly have different geometries and physical characteristics depending on the particular application of the filter cartridge.
However, in any embodiment of the filter group comprising a filter cartridge, said filter cartridge needs to be replaced according to the needs of the motor vehicle, for example in case of maintenance.
Accordingly, a major problem with known filtration systems is to make the engagement and disengagement operation of the filter cartridge and the base assembly simple and intuitive. With this need, there is at the same time a blocking configuration in which the filter cartridge and the base assembly are mutually coupled, such blocking being ensured over time, avoiding the risk of undesired detachment thereof.
In the prior art, solutions of filtering systems are known which provide mutual engagement of the filter cartridge and the base assembly, which require complex engagement and/or disengagement operations, and in some cases additional dedicated components, such as safety plugs.
Disclosure of Invention
It is therefore an object of the present invention, in particular, to provide a fluid filter group which ensures the safe blocking of the filter cartridge against its respective base assembly, but which also allows simple and intuitive engagement and disengagement operations.
This object is achieved by a filter cartridge according to the invention and a base assembly according to the invention. Furthermore, this is also achieved by the fluid filter group according to the invention, by the method of assembling the fluid filter group as claimed in the invention and by the method of disassembling the fluid filter group as claimed in the invention. The invention also shows preferred embodiment variants with other advantageous aspects.

According to further embodiments, the engagement means provides for an inverted positioning of the described first and second engagement members. That is, the first engagement member is positioned on the base assembly and the second engagement member is positioned on the filter cartridge.
According to some embodiments of the invention, the filter cartridge and base assembly are placed in the vehicle in a horizontal position, i.e. extended to a position parallel to the ground plane over which the vehicle is moving.
Innovatively, the filter cartridge, base assembly, fluid filter set in the vehicle described above fully satisfy the objects of the present invention of overcoming the typical drawbacks of the prior art. The object of the present invention, which is to overcome the drawbacks typical of the prior art, is fully met by the innovative assembly and disassembly methods of a fluid filter group.
Advantageously, in practice, the assembly and disassembly operations of the filter cartridge-base assembly are very simple, intuitive and guided.
Advantageously, in the blocking configuration, the engagement means ensure that the two parts maintain a fixed axial position over time. Advantageously, the engagement between the base assembly and the filter cartridge, and in particular the maintenance of the mutual fluid engagement between the two, is ensured. Advantageously, in the embodiment in which the base assembly or the filter cartridge comprises a dedicated housing of the filter medium, the engagement between the base assembly and the cartridge is guaranteed even in "emergency (or burst)" situations, in which overpressure or pressure peaks occur inside said housing.
Advantageously, in some embodiments, the movement in the radial direction of the tooth element is guided by the same mutual engagement operation between the filter cartridge and the base assembly.
Advantageously, the operating means can be easily controlled, if necessary, manually and/or by specially shaped special external control means.
Advantageously, the operating device further comprises safety means adapted to eliminate the risk of the tooth elements being excessively subjected to radial actions.
Advantageously, the axial blocking action is effectively unloaded onto the component due to the inclined edge.
Advantageously, the geometry of the coupling system is simplified to simplify the dimensions of the teeth and their respective seats, and advantageously to minimize the complexity and relative cost of the mould for manufacturing the engaging means.
Advantageously, the assembly method (and conversely the disassembly method) involves, over time, simple, intuitive and reproducible operations.
Thus, another advantage of the present invention is that it cannot be installed on a base assembly of a filter cartridge that is not equipped with a tooth element such as that described. In other words, in a fluid filter group, it is for example not possible to use conventional filter cartridges, to ensure the use of good quality filter cartridges provided by the manufacturer, for example during maintenance operations.
Advantageously, undesired disassembly is prevented in comparison with known coupling systems. In fact, the movement of the tooth elements may only start from the blocking configuration and only be possible when a radial thrust action on the tooth elements is performed.
Advantageously, the tooth elements are prevented from undergoing a radial action greater than that required for the particular device.
Advantageously, the engagement and reciprocal blocking between the filter cartridge and the base assembly is guided and controlled by the geometry of the device itself, ensuring a longer service life of the respective components.
Advantageously, the engagement means provides for mounting the first engagement member in the base assembly and the second engagement member on the filter cartridge.
It is clear that a person skilled in the art may make modifications to the filter cartridge, to the base assembly, to the fluid filter group or to the assembly method to satisfy contingent requirements, all of which are included within the scope of protection defined by the following claims.
