Abstract (en)
[origin: WO2012084437A2] The invention relates to an internal gear pump (1) for a hydraulic vehicle brake system. The invention proposes that axial discs (17) which, by the exertion of pressure on the outer sides thereof, are pressed against gearwheels (2, 4) of the internal gear pump (1) for lateral sealing, be provided on the inner sides thereof with grooves (23) through which the gearwheels (2, 4) convey brake fluid as they are driven in rotation, which brake fluid thereby passes, for lubrication, between the axial discs (17) and the gearwheels (2, 4) of the internal gear pump (1).
