Claims

[Scope of utility model registration request]

(1) A rotor having a plurality of vane grooves around the periphery is eccentrically installed in the casing, and the interior of the casing is partitioned into a plurality of chambers by vanes slidably provided in the vane grooves, and the rotation of the rotor divides the inside of the casing into a plurality of chambers. A pump device configured to change the volume of the rotor, wherein an end face of the rotor faces an oil supply port formed in the casing, and a groove communicating with the vane groove is formed on the end face of the rotor.

(2) The pump device according to claim 1, which is a registered utility model, characterized in that the pump device has a fluid diode in the groove communicating with the vane groove.
