摘要： The present invention relates to a compressed air filter adapter for connecting a filter element (12) to a filter connection housing (13), - wherein the adapter (11) has a flow duct (21) enclosed by a wall (20) for compressed air, - wherein the flow duct (21) at a first end is delimited by a first opening (14), which has 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), which has an inner contour (152) defined by a second edge (151) and an outer contour (153), - wherein the first opening (14) is provided for connection to a filter connection housing (13) and forms an opening cross-section (16), which is defined by the inner contour (142) of the first opening (14), and - wherein the second opening (15) defines an opening on the filter side and forms a second opening cross-section (17), which is defined by the inner contour (152) of the second opening (15), - wherein 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), - and wherein 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) that is 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) comprising constrictions (18) or expansions (19) by removing or adding surface sections, and on the side pointing opposite from the offset direction (R) comprising corresponding expansions (19) or constrictions (18) by adding or removing substantially equally large surface sections.

摘要： The invention relates to a heat exchanger for a refrigerant dryer, in particular for a compressed air refrigerant dryer, comprising at least one first inflow surface element, past which a fluid to be dried, in particular compressed air, can flow during operation of the heat exchanger, and further comprising at least one second inflow surface element, past which a refrigerant fluid can flow as required during operation of the heat exchanger. The first and second inflow surface elements are or can be coupled at least in some areas to at least one cold store chamber that is provided for filling with a cold store medium, and wherein the first and/or second inflow surface elements are connected to at least one heat transfer element which extends into the cold store chamber, and in particular penetrates the cold store chamber.
