Abstract (en)
[origin: EP0379718A2] A device for moving flowing media, in particular liquids, in a delivery line by means of a pump is intended to permit a reduction in the pressure differentials in the case of pump pulsation. For this purpose a piezo counter-pressure generator (20) or a valve (21) controlled by a piezo element is arranged in a branch line (18) of the delivery line (14). The valve may be connected to a fluid reservoir (11) or to the intake line (12). <IMAGE>
