Patent ID: 8632617

Claim:
A filter ( 1 ), comprising: a filter housing ( 2 ); a filter insert received into an interior chamber of said filter housing, said filter insert having a raw side through which a gaseous fluid to be filtered enters said filter insert and a clean side outlet chamber ( 8 ) through which the filtered gaseous fluid exits said filter insert, said filter insert including a filter element ( 3 ); a collecting chamber ( 10 ) extending axially within the filter insert and arranged between said raw side of the filter insert and said clean side outlet chamber of the filter insert and draining liquid separated from the gaseous fluid by the filter ( 1 ); a filter end disk ( 18 ) arranged at an end face on said filter insert, said end disk including a drainage conduit ( 29 ) in fluid communication with said collecting chamber ( 10 ) and operative to drain said separated liquid to an exterior of said filter housing; an elastic circumferential outer seal ( 23 ) mounted on said end disk and operative to fluidicially sealably separate a raw side ( 16 ) of said filter ( 1 ) from said collecting chamber ( 10 ); an elastic circumferential inner seal ( 24 ) arranged at said end disk and operative to fluidically sealably separate a clean side ( 17 ) of said filter ( 1 ) from said collecting chamber ( 10 ); wherein said outer seal ( 23 ) forms a circumferentially extending outer sealing surface ( 25 ), said outer sealing surface facing in radial direction inwardly, wherein said inner seal ( 24 ) forms a circumferentially extending inner sealing surface ( 26 ), said inner sealing surface facing in radial direction outwardly, wherein said outer sealing surface ( 25 ) and said inner sealing surface ( 26 ) are positioned in a concentric arrangement and sealably delimit a circumferentially extending sealing space ( 27 ) positioned radially between said outer and inner sealing surfaces, wherein said outer seal ( 23 ) and said inner seal ( 24 ) are each embodied as an interacting insertable seal, wherein axially connecting said filter to a connecting head ( 12 ) in an axial insertion direction (S), said outer and inner seals sealably interact with said connecting head to form said fluidic seals sealing said receiving space therebetween, wherein the connecting head ( 12 ) has a circumferentially extending web ( 28 ) that is inserted into said sealing space ( 27 ) between said outer and inner seals, wherein said circumferentially extending web ( 28 ) radially seals said sealing space ( 27 ) with the outer and inner seals by clamping or a press fit of said outer and inner seals against said circumferentially extending web ( 28 ).
