Abstract
This invention is directed to a slant plate type compressor, such as a wobble plate type compressor, which is provided with a variable displacement mechanism. The variable displacement mechanism controls the incline angle of the wobble plate due to changes in crank chamber pressure. The variable displacement mechanism comprises a passageway communicating between the suction chamber and the crank chamber, and a valve mechanism to control the opening and closing of the passageway. The valve mechanism includes a first valve control mechanism for directly controlling the opening and closing of passageway and a second valve control mechanism which operates to override the first valve mechanism and open the passageway to operate the compressor at high capacity.
