Abstract: An apparatus for damping pressure pulsation for a compressor of a gaseous fluid in a refrigerant circuit including a housing with an inlet opening and at least one first outlet opening and a piston element movable in an axial direction within a volume enclosed by the housing and supported on the housing in a beared manner via a spring element, wherein the piston element respectively controls a flow cross section of the inlet opening and the first outlet opening, wherein the piston element and the housing have at least one first sealing surface and a second sealing surface. The first sealing surfaces form a first seat and the second sealing surfaces form a second seat, wherein between the seats, one chamber enclosed by the housing and the piston element for expanding the fluid when flowing into the chamber and/or at least one second outlet opening in the housing is formed.
