Abstract

A filter device has a filter housing (2) and a filter element (15) accommodated in the filter housing. The element material (44) of the filter element for filtering a liquid extends between two end caps (40, 42). At least one end cap (40) is mounted on an element receptacle (14). A bearing (46, 54), providing more than one degree of freedom, is used to articulate the filter element (15) on the element receptacle (14) via its one end cap (40). The bearing has a convex bearing surface (46) that is guided in a concave bearing surface (54). The respective bearing surface (46, 54) is part of a respective shell (55a, 55b). At least one shell (55b) has a passage (55c) for liquid media.
