    摘要： In a swash plate type compressor, refrigerant in a discharge pressure region is introduced into a crank chamber through a supply passage while the refrigerant in the crank chamber is drawn out to a suction pressure region through a bleed passage for controlling pressure in the crank chamber, whereby inclination angle of a swash plate is changed. A heat-generating sliding portion is provided in the crank chamber. The supply passage includes a communication port that communicates with the crank chamber and a first throttle portion for throttling the refrigerant. At least parts of the supply passage and the bleed passage are formed in a drive shaft. A part of the bleed passage formed in the drive shaft is located between a part of the supply passage formed in the drive shaft and an outer peripheral surface of the drive shaft.

    摘要： A variable displacement type compressor circulates a refrigerant in an air conditioning circuit. The compressor has a compression mechanism and a displacement controller. The compression mechanism compresses and discharges the refrigerant. The displacement controller controls the discharge amount of the refrigerant of the compressor. The displacement controller further includes a normal control means and a protective control means. The normal control means controls the displacement based on a cooling load. The protective control means controls the displacement based on the value in connection with the rotational speed of the compressor and the actual operating information of the compressor.

    摘要： Method of producing a blank (100) for manufacturing a single-headed piston (38) having a head portion (40) and a neck portion (42) formed integrally with the head portion, for engagement with a drive member (26), the method including: a step of manufacturing a body member (102, 140, 160, 180, 206, 220, 240) including a twin neck section (106) and two cylindrical hollow head sections (108, 142, 162, 182, 208, 222, 242) formed integrally with the twin neck section so as to extend from opposite ends of the twin neck section, the twin neck section consisting of two portions which are mutually integrally formed in series with each other and which correspond to the neck portions (42) of respective two single-headed pistons (38), each hollow head section being open at at least one of opposite ends thereof which is remote from the twin neck section; a step of manufacturing two closing members (104, 148, 166, 186, 200, 226, 246) each for closing an open end of the corresponding hollow head section; and a step of fixing each closing member to the body member, so as to close the open end of the corresponding hollow head section.
