Abstract:
A variable displacement compressor for varying displacement according to the inclination of a drive plate located in a crank chamber, the compressor comprising:a suction pressure zone, the pressure of which is a suction pressure;a discharge pressure zone, the pressure of which is a discharge pressure;a bleeding passage for bleeding refrigerant gas from the crank chamber to the suction pressure zone; anda valve for regulating the bleeding passage, wherein the valve controls the flow of refrigerant gas from the crank chamber to the suction pressure zone such that the valve adjusts the pressure of the crank chamber, and the inclination of the drive plate varies in accordance with the pressure in the crank chamber, wherein the valve has a valve body, which adjusts the opening area of the bleeding passage, an adjuster body, which acts on the valve body, and a housing that houses the adjuster body, wherein a supply passage is formed between the adjuster body and the housing to guide refrigerant gas from the discharge pressure zone to the crank chamber.
