Abstract

Die Erfindung betrifft eine Motor-Pumpen-Einheit mit einem mehrteiligen Gehäuse (25), die eine reversible Innenzahnradmaschine (21) und einen Elektromotor (22) mit einem Rotor (22.1) und einem Stator (22.2) umfasst, der über eine in dem Gehäuse (25) drehbar gelagerte Welle (23) mit der Innenzahnradmaschine (21) gekoppelt ist. Die Welle (23) erstreckt sich mit einem Wellenende von der Innenzahnradmaschine (21) weg axial durch den von der Welle (23) getragenen Rotor (22.1). Ein erster Anschlusskanal und ein zweiter Anschlusskanal münden in eine Arbeitskammer der Innenzahnradmaschine (21) und sind über in dem Gehäuse (25) angeordnete Rückschlagventile mit einer Leckagekanalschleife verbunden, die mit wenigstens einem mit der Arbeitskammer fluidverbundenen Leckagekanal fluidverbunden ist und die einen sich axial durch die Welle (23) erstreckenden Leckage-Wellenkanal und einen damit fluidverbundenen, sich axial durch den Rotor (22.1) erstreckenden Leckage-Rotorkanal und/oder einen zwischen dem Rotor (22.1) und dem Stator (22.2) ausgebildeten Leckage-Spaltkanal aufweist, der mit dem Leckage-Wellenkanal fluidverbunden ist.
