Beschreibung
Zusammenfassung:	An oil pump, includes an inner rotor having outer teeth; an outer rotor having inner teeth which form cells together with the outer teeth, the outer rotor rotating with a prescribed amount of eccentricity with respect to the center of rotation of the inner rotor; an outer ring which causes the center of rotation of the outer rotor to swing along a fan-shaped rotation trajectory having a radius equal to the amount of eccentricity, with respect to the center of rotation of the inner rotor; an operating means which causes a swinging movement of the outer ring; and a pump housing which has a rotor chamber having an intake port and a discharge port, the portion between a final end section of the intake port and a start end section of the discharge port being taken to be a first sealing land.
