Claims

[Scope of utility model registration request]

An outer rotor having a streamlined circumferential protruding surface on the outer periphery is housed in a rotor chamber having a shape in which the outer rotor can be loosely inserted into the casing, and the outer rotor is disposed on opposite circumferential sides of the rotor chamber. This trochoid type oil pump is characterized by having a suction port and a discharge port for suction and discharge from the front and back sides of the inner rotor and the inner rotor.
