Abstract

An exchangeable filter has a filter housing, a filter element, and a connecting member arranged at a filter housing end face. A filter-associated connecting part of a connecting device detachably connects the exchangeable filter with a filter head of a filter device by a plug-in/rotary movement. A filter-associated locking part of a locking device locks the connecting device in a locked state automatically and releasably by the plug-in/rotary movement with a head-associated locking part of the locking device provided at the filter head. The filter-associated locking part has a latching section latching with a head-associated latching section of the head-associated locking part. The filter-associated locking part has a support section on a side of the filter-associated locking part facing away radially from the filter-associated latching section. The support section radially supports the filter-associated locking part relative to the circumferential section of the filter housing in the locked state.

First claim

What is claimed is:

1 . An exchangeable filter comprising:
a filter housing comprising at least one housing-associated circumferential section; at least one filter element arranged in the filter housing; a connecting member arranged at an end face of the filter housing and comprising at least one fluid opening; a filter-associated connecting part of a connecting device configured to detachably connect the exchangeable filter with a filter head of a filter device; at least one filter-associated locking part of at least one locking device configured to releasably lock the connecting device in a locked state; the filter-associated connecting part configured to detachably connect with the filter head by a plug-in/rotary movement relative to a connecting axis of the connecting device; the at least one filter-associated locking part configured to automatically and releasably lock by the plug-in/rotary movement with a head-associated locking part, provided at the filter head, of the at least one locking device; the at least one filter-associated locking part comprising at least one filter-associated latching section configured to latch with a head-associated latching section of the head-associated locking part in a locked state of the at least one locking device; the at least one filter-associated locking part comprising at least one support section provided on a support side of the at least one filter-associated locking part, wherein the support side is facing away, in a radial direction relative to the connecting axis, from the at least one filter-associated latching section; the at least one support section configured to support the at least one filter-associated locking part relative to the at least one housing-associated circumferential section of the filter housing at least in the radial direction at least in the locked state.

2 . The exchangeable filter according to claim 1 , wherein the at least one support section projects on the support side outwardly or inwardly in the radial direction past other sections of the at least one filter-associated locking part at least in the locked state.

3 . The exchangeable filter according to claim 1 , wherein the at least one support section is elastic at least in the radial direction.

4 . The exchangeable filter according to claim 1 , wherein the at least one support section is positioned relative to the connecting axis radially opposite to the at least one filter-associated latching section of the at least one filter-associated locking part.

5 . The exchangeable filter according to claim 1 , wherein the at least one support section is displaced in a circumferential direction about the connecting axis relative to the at least one filter-associated latching section of the at least one filter-associated locking part.

6 . The exchangeable filter according to claim 1 , wherein the at least one support section is a projection or a support arm.

7 . The exchangeable filter according to claim 1 , further comprising at least one intermediate element that, relative to the connecting axis, is arranged radially between the at least one support section and the housing-associated circumferential section.

8 . The exchangeable filter according to claim 7 , wherein the housing-associated circumferential section is provided on a housing cover of the filter housing or is provided on the connecting member, wherein the intermediate element is an intermediate ring.

9 . The exchangeable filter according to claim 7 , wherein the at least one intermediate element is elastic or rigid.

10 . The exchangeable filter according to claim 1 , wherein the at least one filter-associated locking part is at least partially elastic at least in the radial direction.

11 . The exchangeable filter according to claim 1 , wherein the at least one filter-associated locking part is a separate part that is connected indirectly or directly with the filter housing.

12 . The exchangeable filter according to claim 11 , wherein the at least one filter-associated locking part is connected to the connecting member, or to a cover of the filter housing, or to a cover part of the filter housing.

13 . The exchangeable filter according to claim 1 , wherein at least two of the at least one filter-associated locking part are interconnected with each other and are connected indirectly or directly with the filter housing.

14 . The exchangeable filter according to claim 13 , wherein the at least two filter-associated locking parts are interconnected to form a single piece that is connected to the connecting member, or to a cover of the filter housing, or to a cover part of the filter housing.

15 . The exchangeable filter according to claim 1 , wherein the at least one filter-associated latching section comprises a latching nose, a hook section, or a latching receptacle.

16 . The exchangeable filter according to claim 1 , wherein the at least one filter-associated latching section is elastically movable.

17 . The exchangeable filter according to claim 1 , wherein the at least one filter-associated locking part comprises at least one profiling in the form of grooves or bends.

18 . A filter device for fluid, the filter device comprising an exchangeable filter, the exchangeable filter comprising:
a filter housing comprising at least one housing-associated circumferential section; at least one filter element arranged in the filter housing; a connecting member arranged at an end face of the filter housing and comprising at least one fluid opening; a filter-associated connecting part of a connecting device configured to detachably connect the exchangeable filter with a filter head of a filter device; at least one filter-associated locking part of at least one locking device configured to releasably lock the connecting device in a locked state; the filter-associated connecting part configured to detachably connect with the filter head by a plug-in/rotary movement relative to a connecting axis of the connecting device; the at least one filter-associated locking part configured to automatically and releasably lock by the plug-in/rotary movement with a head-associated locking part, provided at the filter head, of the at least one locking device; the at least one filter-associated locking part comprising at least one filter-associated latching section configured to latch with a head-associated latching section of the head-associated locking part in a locked state of the at least one locking device; the at least one filter-associated locking part comprising at least one support section provided on a support side of the at least one filter-associated locking part, wherein the support side is facing away, in a radial direction relative to the connecting axis, from the at least one filter-associated latching section; the at least one support section configured to support the at least one filter-associated locking part relative to the at least one housing-associated circumferential section of the filter housing at least in the radial direction at least in the locked state.

19 . A filter head of a filter device according to claim 18 , the filter head comprising:
a head-associated connecting part comprising a connecting socket, wherein the head-associated connecting part is configured to detachably connect with a filter-associated connecting part of an exchangeable filter by a plug-in/rotary movement relative to a connecting axis of the filter device, wherein the head-associated connecting part comprises at least one fluid chann
