摘要

The invention relates to an internal gear pump (1) for a hydraulic motor vehicle brake system. According to the invention, a separating piece (7) which separates a pump space (6) of the internal gear pump (1) into a suction space (8) and a pressure space (9) is arranged pivotably and diagonally to a circumferential direction in a manner that is movable towards the inside and the outside, and a spring torque is applied to said separating piece, such that the separating piece (7) abuts on one end on the inner side on tooth tips of teeth of a pinion (2) and on the outer side on tooth tips of teeth of a hollow wheel (3) of the internal gear pump (1).
