  • Supply unit with a ceramic internal gear pump
    Patent number: 5618171
    Abstract: Disclosed is a fluid delivery supply unit having an internal gear pump as a pump unit, with a bearing race in which a driven inner gear is arranged on a bearing journal and the inner gear rotates with it by way of toothing engagement with an outer gear arranged between the inner gear and the bearing race, and the inner gear has one tooth fewer than the outer gear so that a pumping action is produced. A low noise level, resistance to corrosion, and a reduced weight, are obtained by forming parts of the internal gear pump, such as the bearing race, inner gear or outer gear, of a ceramic material.
