Abstract

Eine Vorrichtung zum Bewegen von Strömungsmedien, insbesondere Flüssigkeiten, in einer Förderleitung mittels einer Pumpe soll eine Verminderung der Druckunterschiede bei der Pumpenpulsation ermöglichen. Hierzu ist in einer Zweigleitung (18) der Förderleitung (14) ein Piezo-Gegendruckerzeuger (20) angeordnet oder ein mit einem Piezoelement gesteuertes Ventil (21). Letzteres kann an ein Flüssigkeitsreservoir (11) oder an die Saugleitung (12) angeschlossen sein. A device for moving flow media, in particular Liquids in a delivery line by means of a pump are said to Allow reduction in pressure differences in pump pulsation. For this purpose, the delivery line (14) is in a branch line (18) Piezo back pressure generator (20) arranged or one with a Piezo element controlled valve (21). The latter can be a Liquid reservoir (11) or connected to the suction line (12) be.
