Claims

[Scope of utility model registration request]

An inner rotor having external teeth formed on the outer peripheral surface and an outer rotor having internal teeth formed on the inner peripheral surface mesh with each other and rotate around different axes, and the inner rotor and the outer rotor repeatedly expand and compress the plurality of rotors. In a trochoid pump in which a pump chamber is divided, the suction port and the discharge port are limited to the suction start side of the suction port that opens to the pump chamber in the expansion process and the discharge end side of the discharge port that opens to the pump chamber in the compression process. A trochoid pump characterized in that a part of the inner rotor is set outside the tooth bottom of the outer rotor with which the tooth tips of the inner rotor engage.
