Abstract
An internal gear pump for a slip-controlled hydraulic vehicle braking system has a pinion, an internal gear and a separating piece which is arranged between the pinion and the internal gear. The internal gear pump also has an inner part and an outer part, and separates a suction chamber from a pressure chamber. The separating piece is configured to protrude counter to a rotational direction of the internal gear pump beyond a sealing point of the inner part on the outer part such that the inner part and the outer part bear in front of the sealing point against at least one tooth tip of a tooth of the pinion and of the internal gear of the internal gear pump. As a result, tilting of the inner part and of the outer part away from the pinion and from the internal gear about the sealing point is avoided.
