Claims

[Scope of utility model registration request]

A housing formed into a cylindrical shape having an intake port and an exhaust port, a rotary shaft and a rotor disposed within the housing so as to be rotatable eccentrically with respect to the inner peripheral surface of the cylindrical shape, and capable of sliding in the radial direction on the rotor. The vane is inserted into the housing and is always in sliding contact with the cylindrical inner peripheral surface of the housing to forcefully transport air from the intake port to the exhaust port, and the same check is applied to the intake port and the exhaust port. A pump device characterized by being equipped with a valve.
