Abstract

The invention relates to an internal gear pump (1) for a hydraulic vehicle brake system. According to the invention a pump shaft (2) is axially decoupled by means of a drive shaft (20) between a drive motor and the internal gear pump (1) and the drive shaft (20) is radially mounted together with the pump shaft (2) in a sliding bearing (15). The invention achieves a smooth-running internal gear pump (1) having a low bearing load and low seal wear.
