Abstract
A variable displacement compressor has a housing, which defines a crank chamber, a suction chamber, and a discharge chamber. A release 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 is located in the release passage. The release valve regulates gas flow in the release passage. A controller controls the release valve to limit the pressure in the crank chamber to prevent the pressure in the crank chamber from becoming undesirably high. This can prevent the pressure in the crank chamber from excessively increasing.
