Abstract

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.
