摘要： A compressed air filter adapter for connecting a filter element (12) to a filter connection housing (13) includes a flow duct (21) enclosed by a wall (20) for compressed air, the flow duct (21) at a first end being delimited by a first opening (14), having an inner contour (142) defined by a first edge (141) and an outer contour (143), and at a second end by a second opening (15), having an inner contour (152) defined by a second edge (151) and an outer contour (153). The first opening (14) is provided for connection to a filter connection housing (13) and forms an opening cross-section (16), defined by the inner contour (142) of the first opening (14). The second opening (15) defines an opening on the filter side and forms a second opening cross-section (17), defined by the inner contour (152) of the second opening (15).

摘要： A compressed air filter adapter is provided for connecting a filter element (12) to a filter connection housing (13). The adapter (11) has a flow duct (21) enclosed by a wall (20) for compressed air, the flow duct (21) at a first end being delimited by a first opening (14), having an inner contour (142) defined by a first edge (141) and an outer contour (143), and at a second end by a second opening (15), having an inner contour (152) defined by a second edge (151) and an outer contour (153). The first opening (14) is provided for connection to a filter connection housing (13) and forms an opening cross-section (16), defined by the inner contour (142) of the first opening (14). The second opening (15) defines an opening on the filter side and forms a second opening cross-section (17), defined by the inner contour (152) of the second opening (15). The inner contour (142) of the first opening (14) and the inner contour of the second opening (15) are offset from each other, such that the surface center of gravity of the first opening cross-section (16) is displaced in relation to the normal extending from the surface center of gravity of the second opening cross-section (17) in an offset direction (R). The outer contour (143) of the first opening (14) has a basic shape that deviates from the circular shape, such that the outer contour (143) is derived from a transformation of a circle (165) centrically aligned in relation to the normal extending from the surface center of gravity of the second opening (15), the circle in the direction of the offset direction (R) being displaced by a length R1 and defining a displaced circle (166), and on the side of the circle (166) pointing in the offset direction (R) having constrictions (18) or expansions (19) by removing or adding surface sections, and on the side pointing opposite from the offset direction (R) having corresponding expansions (19) or constrictions (18) by adding or removing substantially equally large surface sections.
