Abstract
A variable capacity swash-plate type compressor provided with a suction chamber for refrigerant gas before compression, a discharge chamber for compressed refrigerant gas, a crank chamber for a swash-plate assembly driving reciprocation of compressing pistons in cylinder bores of a cylinder block, a high pressure gas supply passageway fluidly communicating between the discharge chamber and the crank chamber so as to supply the crank chamber with a high pressure gas, a flow choke arranged adjacent to the high pressure gas supply passageway so as to regulate the pressure and flow rate of the high pressure gas flowing through the gas supply passageway, and a control valve unit for controlling extraction of the high pressure gas from the crank chamber toward the suction chamber in response to a refrigerating load. The high pressure gas supply passageway is formed in the cylinder block, and the flow choke is provided in a discharge valve assembly including a valve plate, a discharge valve element, and a valve retainer.
