Problems solved by technology

In this case, the mentioned return shut-off valve and the mentioned thermostat valve are usually constructed at separate locations and thus require a non-negligible amount of assembly effort
A further disadvantage of the known backflow shut-off valve is that it is usually designed as a prefabricated component and installed in this state
As a result, different variants of the backflow shut-off valve are separately available for different vehicle variants, resulting in relatively high storage and logistics costs

Embodiment Construction

[0021] according to figure 1 , according to the invention, the axially through-flow valve element 1 has a backflow shut-off valve 2 and a bypass valve 3 arranged coaxially therewith and connected in series. The bypass valve 3 and the backflow shut-off valve 2 are arranged axially spaced apart from one another in the valve slide 1 . If one considers the return shut-off valve 2 in its installed state in the filter housing 4 of a filter device 5 (for example, an oil filter of an internal combustion engine in a vehicle), it can be seen that the spool 1 is arranged in the original filter device. 5 and pump 6 in the line. If the backflow shutoff valve 2 is open, it can distribute a fluid flow, for example an oil flow, between the oil cooler 7 and the filter device 5 depending on the switching position of the bypass valve 3 .

[0022] In order to be able to manufacture the spool 1 as flexibly as possible here, a modular system 8 according to the invention is provided (see figure ...

Abstract

The invention relates to a modular system (8) for an axial through-flow valve insert (1) with a return valve (2) and a lid (9) coaxially attachable thereto and / or a bypass valve (3) attachable thereto. This makes it possible to achieve a significantly higher flexibility in options. The invention also relates to a filter unit.

Description

technical field [0001] The invention relates to a modular system for a valve element through which axial flow can pass. Furthermore, the invention relates to a filter device having at least one cartridge assembled from such a modular system. Background technique [0002] In conventional filter devices, such as oil filters or oil modules, so-called thermostat valves are used, which guide the oil past the oil cooler during the cold start phase, whereby the oil can be drained more quickly The temperature rises, and thus the internal combustion engine reaches its operating temperature earlier. In addition, a return shut-off valve is arranged in such an oil circuit, which prevents the filter device from running unloaded when the internal combustion engine is stopped, so that the required oil pressure reappears relatively quickly when restarting. In this case, the mentioned return shut-off valve and the mentioned thermostat valve are usually constructed at separate locations and...
