Filter Device, Especially Liquid Filter

Abstract

A filter device comprises a hollow cylindrical filter element in a filter housing. The fluid that is to be purified is to radially flow through the filter element. The interior of the filter element forms an axial flow chamber for the fluid. An end plate is arranged on the front side of the filter element. An annular neck, onto which a sealing element is injection-molded, is connected to the end plate.

         12 . A liquid filter device for filtering oil or fuel, comprising:
 a filter housing;   a hollow cylindrical filter element arranged in said filter housing and having an axial direction, wherein a fluid to be filtered flows radially through said filter element;   wherein an interior of said filter element ( 2 ) forms an axial flow space for said fluid after filtering;   said filter element further comprising
 a terminal disk arranged at an axial end face of the filter element; 
 an axially projecting annular socket secured to said terminal disk, said annular socket including an axially outward projecting annular wall surrounding an open central portion; and 
 a sealing element arranged on said annular socket over at least a portion of said annular wall, said sealing element operative to form a seal between said terminal end disk and said filter housing to seal between a raw side and a clean side of said filter element; 
   wherein said sealing element comprises sealing material injection-molded onto said axially projecting annular socket.   
     
     
         13 . The filter device of  claim 12 , wherein said sealing material is comprised of a silicone material. 
     
     
         14 . The filter device of  claim 13 , wherein said silicone material is a fluorine-silicone-rubber (FVMQ). 
     
     
         15 . The filter device of  claim 12 , wherein said annular socket includes shaped elements formed thereon and configured to improve adhesion of said sealing element to said annular socket. 
     
     
         16 . The filter device of  claim 15 , wherein said shaped elements are embodied as cutouts formed into said annular wall of said socket. 
     
     
         17 . The filter device of  claim 12 , further comprising:
 a second axially projecting annular socket secured to said terminal disk and arranged concentrically to said first socket, said second annular socket including an axially outward projecting annular wall surrounding an open central portion; and   a sealing element arranged on said second annular socket over at least a portion of said annular wall, said sealing element operative to form a seal between said terminal end disk and said filter housing;   wherein said sealing element is injection-molded onto said second annular socket.   
     
     
         18 . The filter device of  claim 12 , wherein
 said socket includes a section extending at an angle to said axial direction and onto which section said sealing material is injection-molded.   
     
     
         19 . The filter device of  claim 12 , wherein
 said socket including a first axially extending section and a second section connected to said first section and extending at an angle relative to said first section, said second section extending perpendicularly relative to said first axially extending section.   
     
     
         20 . The filter device of  claim 18 , wherein said socket includes a section configured to support said sealing element at a non-perpendicular and non-zero angle relative to said terminal disk. 
     
     
         21 . The filter device of  claim 12 , wherein said sealing material arranged onto an inner side, an outer side, and a free end face of said socket. 
     
     
         22 . The filter device of  claim 12 , wherein said socket is formed monolithically with said terminal disk.
