Abstract
Official abstract text for this publication.
An internal gear pump for a slip-controlled hydraulic vehicle braking system includes a pinion, a ring gear, and a filler piece (sickle). The filler piece has an inner part extending in a curved manner in the peripheral direction and an outer part extending in a curved manner in the peripheral direction. The inner part and the outer part are interconnected in a hinged manner on the suction-sided ends. A leg spring is arranged between the inner and outer parts and is configured to separate the inner and outer parts and press against the tops of the teeth of the pinion and the tops of the teeth of the ring gear of the internal gear pump.
First claim
Opening claim text (preview).
The invention claimed is: 1. An internal gear pump for a hydraulic vehicle braking system, comprising: an internally toothed ring gear; an externally toothed pinion arranged eccentrically in the ring gear and configured to mesh with the ring gear in a circumferential section, the pinion and the ring gear forming a crescent-shaped cavity opposite the circumferential section in which the pinion meshes with the ring gear; and a filler piece arranged in the cavity, the filler piec…
