Abstract
A filter has a filter housing with a housing cover coupled to a housing part to close a receiving space receiving filter elements each provided with a filter medium body and a frame device around the filter medium body. The filter housing has a radially inwardly projecting, circumferential contact shoulder in the receiving space. The housing cover, when mounted, exerts an axial clamping force on the frame device of a first filter element. An axial end of the first filter element facing away from the housing cover rests on the frame device of a second filter element. The clamping force is transmitted through frame device of first filter element to frame device of second filter element. The frame device of the second filter element has a circumferential seal with a hollow chamber profile pressed by the clamping force on the contact shoulder to seal-tightly contact the contact shoulder.
