A pulsation damper (Fig. 2) serves to reduce pressure fluctuations in delivery lines and the like, in particular at high pressures. To this end, a pulsator tube (10) is provided in a delivery-flow line (5, 6). Located in the pulsator tube (10) is a nozzle tube (11) which can be axially displaced in a reciprocating manner to a limited extent on the flow side and is acted upon by a spring (12) acting against the flow direction. In this arrangement, the nozzle tube together with the spring forms an oscillation system working in the resonance range of the spring and matched to the pulsation sequence of the incoming pump pressure, an annular gap (S) being provided between the outer contour of the nozzle tube (11) and the inner wall (28) of the pulsator tube (10). <IMAGE>
