Abstract
A variable displacement compressor has a housing, which defines a crank chamber, a suction chamber, and a discharge chamber. A bleed passage connects the crank chamber to the suction chamber, which allows gas to flow from the crank chamber to the suction chamber. A release valve, which is a reed valve, is located in the bleed passage. The release valve varies the opening of the bleed passage in accordance with the difference between the pressure in the crank chamber and the pressure in the suction chamber. This can prevent the pressure in the crank chamber from excessively increasing.
