Abstract
A slant plate type compressor, such as a wobble plate type compressor, with a variable displacement mechanism is disclosed. The compressor has a valve mechanism to control the opening and closing of a passageway connected between the crank chamber and suction chamber. The valve mechanism operates in accordance with the pressures in the crank chamber and the suction chamber of the compressor. Therefore, the compressor has improved cooling characteristics and lubricating oil does not leak out of the compressor into the external refrigeration circuit.
