Abstract (en)
[origin: US5499910A] Internal gear pump with an internal gear, a thrust plate arranged on each side of the internal gear, a powered external pinion arranged eccentrically relative to the internal gear and meshing with it, and a sickle-shaped, floating filler part split in peripheral direction and bearing with its blunt end on an axial support pin. The first segment of the filler part that faces the teeth of the pinion has a greater radial thickness than its second segment facing the teeth of the internal gear. The first segment features in the parting interface at least one axially extending groove for accommodation of a sealing element. The first segment features at least one stop for restricting wear on the surface facing the teeth of the pinion.
