Claims

[Scope of utility model registration request]

A rotor rotatably supported within a housing and having a fan-shaped groove on an end face whose depth changes in an arc shape, the rotor being rotatably sealed within the housing, and having a fluid suction passage, a discharge passage and a cover having a discharge valve;
Inside this cover is a vane that sweeps the fan-shaped groove that rotates in and out in the direction along the center line of the critter and separates a suction chamber and a discharge chamber whose volumes change, and the tip of this vane is A fluid compressor characterized by comprising a spring that presses against and biases the bottom surface of the fan-shaped groove.
