Abstract

Die offenbarte Drehkolbenpumpe (20) besteht aus mindestens zwei sich gegensinnig bewegenden Drehkolben (22) und einem ovalen Pumpengehäuse (28). Jeder Drehkolben (22) weist Drehkolbenflügel auf und ist mit mindestens einem Kontaktelement (34a) versehen. Die mindestens zwei Drehkolben (22) sind an den Kontaktstellen ihrer Flanken (24), an denen die mindestens zwei Drehkolben (34) ein Reibpaar bilden, mit jeweils mindestens einem Kontaktelement (34a) versehen. Das ovale Pumpengehäuse (28) ist an seiner Innenseite (32) ebenfalls mit mindestens einem austauschbaren Kontaktelement (34b) versehen.
