ABSTRACT:
A slant plate type refrigerant compressor, such as a wobble plate type compressor, with a variable displacement mechanism for use in a refrigeration circuit is disclosed. The compressor has a control mechanism to control the pressure in a crank chamber responsive to the pressure in the suction chamber, and another control mechanism to control the pressure in the crank chamber responsive to the temperature of refrigerant gas in the suction chamber. Therefore, the capacity of the compressor can be more accurately controlled in response to changes in the air conditioning load, such as the temperature in a passenger compartment of an automobile.
