摘要： The invention relates to an arrangement for forming a seal between components (11, 33) which have sealing zones (37, 51), said sealing zones facing each other in a functional position of the components. A sealing element (43; 57) is provided on the sealing zone (37, 51) of one component (11, 33) and a sealing surface (51) is provided on the sealing zone (37, 51) of the other component (11, 33) in order to form a radial seal, and the components (11, 33) can be brought into the functional position by a relative movement which is carried out in the axial direction, said sealing element (43; 57) sealingly interacting with the sealing surface (51) in said functional position. The invention is characterized in that the arrangement has a third component (61) which is associated with an actuating part (62) that acts on the sealing element (43; 57) in the functional position of the components (11, 33) so as to deform said element in order to increase the sealing force.

摘要： A filter device, having a filter housing (1) which has a filter head (3), a filter pot (7) and a removable housing cover part (51) and which accommodates a filter element (13) which separates a non-filtrate side (15) from a filtrate side (17), and having a bypass valve device which has a valve closure element (65) which is preloaded by means of a closing spring (69) into a closed position in which it bears against a valve seat part (74) and which, if the filter element (13) is blocked, passes into a position in which it opens up a fluid path from the non-filtrate side (15) to the filtrate side (17), by passing the filter element (13), is distinguished by the fact that the valve closure element (65) and the closing spring (69) are arranged on the cover part (51) and the valve seat part (74) is situated on an element cap (43) of the filter element (13), which element cap has a receiving part (45) which forms an enclosure for that end of the filter material (27) of the filter element (13) which faces toward the cover part (51).
