摘要： An internal gear pump includes a ring gear and a pinion configured to mesh with the ring gear. The ring gear and pinion delimit a pump chamber extending from a suction region to a pressure region. The internal gear pump also includes an axial disk arranged on front faces of the ring gear and the pinion and includes a lubricant feed from the suction region between the axial disk and the ring gear and pinion. The lubricant feed includes a lubricant channel which passes through the axial disk. A wedge gap is delimited between the axial disk and the ring gear and pinion. The wedge gap communicates with the suction region and, when the ring gear and the pinion are driven in rotation, a lubricating film forms between the axial disk and the ring gear and pinion.
