Claims

[Scope of utility model registration request]

a compression mechanism having a suction chamber that receives refrigerant from the evaporator of the air conditioner; a compression chamber that sucks in the refrigerant through the suction chamber and compresses the refrigerant; A discharge chamber for discharging to a condenser, a working pressure path, a pressurizing chamber into which working pressure is introduced from the discharge chamber through the working pressure path, and a pressure receiving member that moves in response to the pressure in the pressurizing chamber, the pressure receiving member There is a suction amount variable mechanism that can change the suction amount of refrigerant from the suction chamber to the compression chamber according to the movement of the member, and a suction amount variable mechanism that is installed on the working pressure path and adjusts the working pressure supplied to the pressurizing chamber. A control valve that controls the operation of the variable suction amount mechanism, and a control valve that drives the control valve to change the amount of refrigerant sucked into the compression chamber, and variably controls the amount of refrigerant discharged from the discharge chamber to the condenser. A variable capacity compressor comprising a variable control means, wherein the variable suction amount mechanism has an orifice hole that gradually reduces the pressure in the pressurizing chamber, and the variable control means engages with a control valve; A drive unit that generates a driving force corresponding to the control signal to drive the control valve, a sensor that detects the operating state of the air conditioner, and a control signal that responds to the operating state of the air conditioner based on the detection information from the sensor. A variable capacity compressor, comprising: a controller for providing power to a drive unit.
