Abstract

The invention relates to an internal gear pump (1) serving as a return pump for a slip-controlled hydraulic vehicle brake system. The invention proposes mounting a ring gear (4) of the internal gear pump (1) in a bearing ring (5) made of plastic and have a pressure pocket (12) on a pressure side P of the internal gear pump (1), wherein the pressure pocket (12) is subjected to an outlet pressure from the internal gear pump (1). The invention has the effect of balancing the radial forces on the ring gear (4).
