Abstract
An internal gear pump for a hydraulic vehicle brake system includes a pump shaft, a pinion, a ring gear, a first axial plate, and a second axial plate. The pinion is disposed on the pump shaft, is configured to rotate conjointly therewith, and is arranged eccentrically within the ring gear so as to mesh therewith. The first and second axial plates are adjacent to the pinion and the ring gear. A toothing on at least one of the ring gear and the pinion is configured such that an axial width of a root of a respective tooth is greater than an axial width of a crest of the respective tooth. A corresponding method relates to producing such an internal gear pump.
