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 having a partitioned pump chamber, the tooth bottoms of the outer rotor with which the tips of the teeth of the inner rotor engage are set outward from a suction port that opens into the pump chamber in the expansion process and a discharge port that opens into the pump chamber in the compression process. and a housing in which the inner rotor and the outer rotor are housed, with grooves through which the tooth bottoms of the outer rotor pass and adjacent pump chambers communicating with each other facing the suction start side of the suction port and the discharge end side of the discharge port. A trochoid pump characterized by being installed on the sliding surface of.
