Abstract

Eine Wälzkolbenpumpe weist mehrere, jeweils eine Pumpstufe (50, 52, 54, 56, 58, 60) ausbildende mehrzähnige Drehkolbenpaare (10, 48, 49) auf. Benachbarte Pumpstufen (50, 52, 54, 56, 58, 60) sind über Verbindungskanäle (30, 34, 77, 84, 86, 88, 90) miteinander verbunden. Zur Verringerung der Herstellungskosten ist es erfindungsgemäß vorgesehen, die Verbindungskanäle (30, 34, 77, 84, 86, 88, 90) in benachbarte Pumpstufen (50, 52, 54, 56, 58, 60) voneinander trennenden Zwischenwänden (74, 76, 78, 80, 82) anzuordnen.
