Abstract: A damping device for fluids subject to pressure pulsations, having at least one hydraulic accumulator (2), the accumulator housing (4, 6) of which contains a movable separating element (18), which separates a gas side (14) from a fluid room (16) and can be pressurized by a fluid present in the fluid room (16), is characterized in that a damper housing (34) having a second fluid room (38) is provided as a component of the accumulator housing (4, 6), wherein through said second fluid room (38) the fluid subject to pressure pulsations can flow and the second fluid room (38) contains a second movable separating element (40), which separates the second fluid room (38) from the first fluid room (16) of the hydraulic accumulator (2) without dead space.
