Claims

[Scope of utility model registration request]

A front side plate and a rear side plate that close openings at both ends are attached to a cylindrical cam ring to form a rotor housing chamber, and a rotor fixed to a drive shaft is rotatably arranged in the rotor housing chamber. , vanes slidingly in contact with the inner circumferential surface of the cam ring are disposed in radial slits formed in the rotor so as to be freely protrusive and retractable, and a compression chamber that communicates with the discharge port as the rotor rotates is formed between each vane. A vane regulating member is provided, which is provided with a pressure sensing means that operates in response to a discharge pressure of a predetermined value or higher at the outlet 1, and is displaced in accordance with the operation of the pressure sensing means, and prevents the vane from sliding into contact with the inner circumferential surface of the cam ring. A rotary vane compressor characterized by the provision of a rotary vane compressor.
