Pulsation damping capsule

摘要

A pulsation damping capsule including at least one hermetically joint-sealed metal membrane housing made of at least two preferably concave hemispheres, the housing being provided for separating an inner space from a surrounding pressure medium, wherein the hemispheres are connected together along a peripheral seam firmly bonded such that the pulsation damping capsule can be compressed and expanded as an energy accumulator with spring elasticity due to the effect of the pressure medium. A pulsation damping device is provided which is both dimensioned to withstand stresses and is simple to produce, the pulsation damping effect of which can be tailored especially easily to the existing conditions. Further disclosed is a pulsation damping module for housing a plurality of pulsation damping capsules.

1. A pulsation damping capsule comprising:
at least one metal diaphragm housing which is joined in a hermetically sealed manner from at least two shells and separates an inner space from a surrounding pressure medium, the shells being connected to one another along a circumferential seam with a material to material fit in such a way that the pulsation damping capsule is configured to be elastically compressed and expanded as an energy accumulator as a consequence of pressure medium action, and a filling element at least partially filling an inner space of the pulsation damping capsule for a stop function, the filling element composed of a metallic or a plastic material, and provided as an insert part.
