Abstract
A filter insert for being removably arranged in a filter housing includes a first connection arrangement for engaging a corresponding second connection arrangement of a filter housing lid for a connection to the filter housing lid. The first connection arrangement is arranged to simultaneously prevent a relative rotational movement between the filter insert and the filter housing lid and allow a relative axial movement between the filter insert and the filter housing lid.
Claims31
A filter insert for being removably arranged in a filter housing wherein the filter insert comprises:
- a first connection means for engaging a corresponding second connection means of a filter housing lid for a connection to the filter housing lid;
- a filter material body having a cylindrical shape;
- and
- an upper plate shaped panel arranged to delimit the filter material body at one of its axial ends, wherein the first connection means is integrally formed with the upper plate shaped panel,
- wherein the first connection means comprises a wall portion with at least one radial opening for receipt of a projection extending from the lid to allow a relative axial movement between the filter insert and the filter housing lid for only a predetermined first distance, and wherein sections of the wall portion at opposite ends of the radial opening in the axial direction defines axially spaced stops for limiting the relative axial movement between the filter insert and the filter housing lid to predetermined first distance, and wherein the radial opening is arranged to simultaneously prevent a relative rotational movement between the filter insert and the filter housing lid.
A filter arrangement comprising:
- a filter insert for being removably arranged in a filter housing, wherein the filter insert comprises
- a first connection means,
- a filter material body having a cylindrical shape, and
- an upper plate shaped panel arranged to delimit the filter material body at one of its axial ends, wherein the first connection means is integrally formed with the upper plate shaped panel;
- and
- a filter housing lid for closing the filter housing, wherein the filter housing lid comprises a second connection means,
- wherein the first connection means and the second connection means are formed by male-female portions, wherein the male portion is formed on the filter housing lid and the female portion is formed on the filter insert, the female portion comprises a wall portion with at least one radial opening for receipt of the male portion extending from the lid to allow a relative axial movement between the filter insert and the filter housing lid for only a predetermined first distance, and wherein sections of the wall portion at opposite ends of the radial opening in the axial direction defines axially spaced stops for limiting the relative axial movement between the filter insert and the filter housing lid to the predetermined first distance, and are arranged to prevent a relative rotational movement between the filter insert and the filter housing lid by a tight fit circumferentially.
