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.
Claims8
A filter device for filtering a liquid, comprising:
- a hollow cylindrical filter element (2) for arrangement in a filter housing (3) that is radially to be flowed through by the fluid to be purified;
- wherein an open interior of the filter element (2) forms an axial flow space for the fluid in the interior;
- the filter element further comprising:
- a terminal disk (4) arranged on an axial end face of the filter element (2), the terminal disk having an open central portion opening through the end disk into the interior;
- a first axially projecting annular socket (6) having a first axial end secured onto the terminal disk, the first annular socket including an axially outwardly projecting annular wall (6) circumferentially surrounding the open central portion;
- and
- a sealing element arranged on the first annular socket over at least a portion of the annular wall, the sealing element operative to form a seal between the terminal end disk (4) and the filter housing to seal between a raw side and a clean side of the filter element;
- wherein the sealing element comprises sealing material (8) injection-molded onto the first axially projecting annular socket (6);
- a second axially projecting annular socket (9) having an axial end secured onto the terminal disk (4) and arranged concentrically to the first socket (6), the second annular socket (9) including an axially outward projecting annular wall surrounding the open central portion;
- and
- a sealing element arranged on the second annular socket (9) over at least a portion of the annular wall, the sealing element operative to form a seal between the terminal end disk (4) and the filter housing (3);
- wherein the sealing element comprises sealing material (8) injection-molded onto the second annular socket.
