Abstract:
1. An adapter ( 1 , 1 ′) for fastening a filter element ( 25 , 25 ′) in a cylindrical receiving opening ( 18 ) of a bottom part ( 19 ) of a lower piece of a filter housing, said adapter comprising first and second parallel peripheral grooves ( 3 , 5 ) on an outer circumference of the adapter ( 1 , 1 ′) and formed with outwardly facing base surfaces ( 6 ), a dividing wall separating the peripheral grooves ( 3 , 5 ) and having oppositely facing first and second inner side surfaces ( 10 , 11 ) facing into the respective first and second peripheral grooves ( 3 , 5 ), first and second outer side surfaces ( 12 , 13 ) formed respectively in the first and second peripheral grooves ( 3 , 5 ) and facing toward the respective first and second inner side surfaces ( 10 , 11 ), first and second seals ( 4 , 7 ) arranged into the first and second peripheral grooves ( 3 , 5 ) to permit fluid-tight separation of a non-filtrate chamber, which surrounds an external jacket of the filter and from which medium to be filtered can be delivered to the filter, from a filtrate chamber into which the filtrate can be introduced from the filter, the seals ( 4 , 7 ) being injection molded onto the base surfaces ( 6 ) of the peripheral grooves ( 3 , 5 ), and engaging the first and second inner side surfaces ( 10 , 11 ) while being at a distance ( 16 , 17 ) from the first and second outer side surfaces ( 12 , 13 ) the first and second seals ( 4 , 7 ) being connected to each other via at least one web ( 20 ) extending in an axial direction, the web ( 20 ) being spaced outward from the base surfaces ( 6 ) and engaging an outer circumferential surface of the dividing wall, the seals ( 4 , 7 ) being unconnected to one another on opposite circumferential sides of the web ( 20 ).
