Claims

[Scope of utility model registration request]

A rotor is rotatably accommodated and supported between a front side plate and a rear side plate that are fixed to both ends of the cylinder in the housing, and the space between the inner circumferential surface of the cylinder and the outer circumferential surface of the rotor is Along with forming compartments in the compression chamber,
As the rotor rotates, each compression chamber is alternately communicated with the suction chamber and discharge chamber to suck, compress, and discharge refrigerant gas, and there is a capacity between the front side plate and the rotor to control the maximum volume when the compression chamber is closed. A first pressure chamber in which a control plate is interposed so as to be rotatable in a reciprocating manner and into which refrigerant gas corresponding to the discharge pressure is introduced, and a second pressure chamber into which oil corresponding to the discharge pressure is introduced via an opening/closing control valve mechanism. In a vane compressor provided with a drive mechanism that drives the capacity control plate by pressure opposition between the two pressure chambers via a sliding partition wall, an oil pool portion connected to the discharge chamber is connected to the rear side plate and the housing. A variable displacement vane compressor, in which a planar heating element that generates heat when energized is fixed to an outer surface of an oil pool forming wall of a housing that is formed between the rear side plates and forms an oil pool part together with the rear side plate.
