Motor/pump unit, especially for antislip brake systems

Abstract

The present invention relates to a motor/pump unit, especially for slip-controlled motor vehicle brake systems, including an accommodating member for hydraulically active components, an internal gear pump arranged in a bore of the accommodating member and comprising pump components such as a pinion/internal gear combination arranged between two housing parts, wherein the pump components form a pre-assembled unit, and including a motor for driving the internal gear pump. An object of the invention is to devise a motor/pump unit, which allows a space-saving and low-cost integration of an internal gear pump in an accommodating member. This object is achieved in that the housing parts can be arranged preliminarily by at least one securing element in such a fashion that the final alignment of the housing parts relative to each other takes place when the unit is inserted into the accommodating member.
