Abstract

Die Erfindung betrifft eine Motor-Pumpen-Einheit (20) mit einem Elektromotor (22) und einer reversiblen Innenzahnradmaschine (21). Letztere hat ein mehrteiliges Gehäuse (25) in dem ein außenverzahntes Ritzel (26) und ein innenverzahntes Hohlrad (30) angeordnet sind. Zwischen den Zahnrädern (26, 30) ist ein Freiraum ausgebildet, in dem ein mehrteiliges Füllstück angeordnet ist. Das Füllstück umfasst mehrere radial bewegliche Radialdichtsegmente, zwischen denen ein Radialspalt ausgebildet ist. Zwischen axialen Stirnfächen der Zahnräder (26, 30) und einem Gehäuseteil (25.1, 25.2) des Gehäuses (25) ist eine axial bewegliche Axialdichtplatte (58.2) angeordnet. Diese weist eine zu den Stirnflächen der Zahnräder (26, 30) hin offene, mit Druckmittel beaufschlagbare Dichtplatten-Steuernut auf, die zu dem Radialspalt hin offen ist und diesem unmittelbar gegenüber liegt. Das Ritzelsegment und/oder das Hohlradsegment weisen einen mit Druckmittel beaufschlagbaren, sich quer erstreckenden Radialdichtsegment-Steuerkanal auf, der zu dem Radialspalt hin offen ist und der unmittelbar in den Radialspalt mündet.

The invention relates to a motor-pump unit (20) with an electric motor (22) and a reversible internal gear machine (21). The latter has a multipart housing (25) in which an externally toothed pinion (26) and an internally toothed ring gear (30) are arranged. Between the gears (26, 30) is a free space formed in which a multipart filler is arranged. The filler comprises a plurality of radially movable radial sealing segments, between which a radial gap is formed. Between axial Stirnfächen the gears (26, 30) and a housing part (25.1, 25.2) of the housing (25) an axially movable Axialdichtplatte (58.2) is arranged. This has a to the end faces of the gears (26, 30) towards open, acted upon by pressure medium sealing plate-control groove, which is open to the radial gap and this is directly opposite. The pinion segment and / or the Hohlradsegment have a pressurizable means, transversely extending Radialdichtsegment control channel, which is open to the radial gap and opens directly into the radial gap.
