Liquid filter

Abstract

The invention relates to a liquid filter (1) comprising a filter housing (10), a ring filter insert (2) and a cover (16), the bottom (18) of the housing (10) containing an eccentric outlet (13) for emptying the housing (10) when the filter insert (2) is removed. The filter insert (2) consists of a filter material body (20) surrounded by front panels (21, 22). A blocking element for the outlet (13) is arranged on the front panel (22) facing the bottom (18), and positioning means are provided on the filter insert (2) and on the housing (10), said positioning means bringing the blocking element (24) into engagement with the outlet (13) when the filter insert (2) is inserted into the housing (10). The filter (1) according to the invention is characterised in that the first positioning means is an inclined plane (3) that is embodied or arranged a) on the outer circumference of a filter housing part (15) arranged inside the ring filter insert (2), b) on the inner circumference of the ring filter insert (2), c) on the outer circumference of the ring filter insert (2), or d) on the inner circumference of the filter housing (10); and the second positioning means is a radially protruding nose (4) embodied or arranged, opposite the inclined plane (3), a) on the inner circumference of the ring filter insert (2), b) on the outer circumference of the filter housing part (15) arranged inside the ring filter insert (2), c) on the inner circumference of the filter housing (10), or d) on the outer circumference of the ring filter insert (2). When the ring filter insert (2) is rotated in relation to the filter housing (10), the inclined plane (3) and the nose (4) can be moved in relation to each other in such a way that they slide along each other and bring the blocking element (24) into engagement with the outlet (13).

Description

technical field [0001] The invention relates to a liquid filter, in particular an oil filter of an internal combustion engine, with a filter housing, with a ring filter element arranged in it replaceably and with a filter housing that closes the filter housing during operation. , a removable cover, wherein the filter housing has at least one inlet for the raw liquid to be filtered into the raw side (Rohseite) of the filter housing and from the filter housing A return opening for the filtered purified liquid originating from the clean side, wherein an eccentric outlet for emptying the filter housing is arranged in the bottom of the filter housing when the annular filter element is removed (Ablauf), wherein the annular filter element consists of a hollow-cylindrical filter material body surrounded on the end side by an end disk, and the raw side and the clean side are separated from each other, wherein a bottom-facing end disk is arranged for An eccentric blocking element of th...

Problems solved by technology

[0007] The known filter element is significantly extended in its structural dimensions due to the guide means, which requires an enlarged filter housing while maintaining the filter area, or leads to a larger size of the filter element while maintaining the same dimensions of the filter housing.
