Abstract
A fluid filter for a motor vehicle includes a filter housing and a filter cartridge which is fixable on the filter housing by rotating around a longitudinal axis of the filter cartridge. A holding element having a web is disposed on an end plate of the filter cartridge where the web protrudes from a wall of the holding element and where the wall is formed as a spiral shape. The web of the holding element is engageable behind a holding web of a counter bearing disposed on the filter housing that is spiral shaped. The holding web has an incline in a rotational direction in comparison to an abutment region of the filter housing on which a sealing element of the filter cartridge abuts.
Claims10
A fluid filter for a motor vehicle, comprising:
- a filter housing;
- and
- a filter cartridge which is fixable on the filter housing, wherein the filter cartridge has a receiving chamber in which a filter material is disposed and wherein the filter cartridge is fixable on the filter housing by rotating around a longitudinal axis of the filter cartridge;
- wherein a holding element having a web is disposed on an end plate of the filter cartridge, wherein the web protrudes from a wall of the holding element, and wherein the wall is formed as a spiral shape when seen radially to the longitudinal axis;
- wherein the web of the holding element is engageable behind a holding web of a counter bearing disposed on the filter housing that is spiral shaped when seen radially to the longitudinal axis;
- wherein the holding web has an incline in a rotational direction when seen in a direction of the longitudinal axis in comparison to an abutment region of the filter housing on which a sealing element of the filter cartridge abuts.
A filter cartridge for a fluid filter of a motor vehicle which is fixable on a filter housing of the fluid filter, comprising:
- a receiving chamber in which a filter material is disposed and wherein the filter cartridge is fixable on the filter housing by rotating around a longitudinal axis of the filter cartridge;
- and
- a holding element having a web is disposed on an end plate of the filter cartridge, wherein the web protrudes from a wall of the holding element and wherein the wall is formed as a spiral shape when seen radially to the longitudinal axis;
- wherein the web of the holding element is engageable behind a holding web of a counter bearing disposed on the filter housing that is spiral shaped when seen radially to the longitudinal axis;
- wherein a distance of the web of the holding element from a surface of the end plate facing away from the filter material in a rotational direction, in which the filter cartridge is rotatable around the longitudinal axis for fixing the filter cartridge on the filter housing, has an incline.
