A pulsation damping capsule for connection to the pressure side of a piston pump having a metal membrane housing that is assembled from two membrane shells joined together in a hermetically sealed manner. The metal membrane housing separates an internal space from a surrounding pressure medium. The membrane shells are connected along a circumferential seam such that the pulsation damping capsule can compress and expand in a resilient-elastic manner as an energy convertor when subjected to external pressure as a result of pressure medium pulses. A reshapeable mass is arranged in the internal space and when the membrane shells are in the resilient-elastically compressed state, the mass completely fills an intermediate space that remains between the two membrane shells, so that the mass is precisely matched to the internal contour of the reshaped membrane shells while avoiding the formation of hollow spaces.

Pulsation dampening capsule

In a piston pump, in particular, for the pressure fluid conveyance in hydraulic, slip-controlled brake systems, comprising at least one piston, a suction valve and a pressure valve, it will be possible for the suction and pressure valves to be externally checked in that the suction valve and the pressure valve are formed on a structural unit adapted to be separately handled. Preferably, the structural unit comprises a sleeve-type section in which the piston is guided.
