Abstract

An internal gear pump for a hydraulic vehicle brake system has axial discs which, by the exertion of pressure on the outer sides thereof, are pressed against gearwheels of the internal gear pump for lateral sealing, provided on the inner sides thereof with grooves through which the gearwheels convey brake fluid as they are driven in rotation, which brake fluid thereby passes, for lubrication, between the axial discs and the gearwheels of the internal gear pump.
