Abstract:
1. A pulsation damping capsule for connection to the pressure side of a piston pump, comprising at least one metal membrane housing that is assembled from two membrane shells that are joined together in a sealed manner and the metal membrane housing separates an internal space from a surrounding pressure medium, wherein the membrane shells are mutually connected along a circumferential seam in such a manner 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 a resilient-elastically compressed state the mass completely fills the internal space that remains between the two membrane shells, so that the mass is precisely matched to the internal contour of the membrane shells while avoiding the formation of hollow spaces in the internal space; wherein the mass is inserted in the form of a film as an insertion part into the internal space of the two membrane shells prior to the two membrane shells being joined together and mutually connected by material engagement.
