摘要： A swash plate type variable displacement compressor comprises cylinder bores, pistons, a suction chamber and a discharge chamber. A suction valve introduces a low pressure gas into a working chamber in each cylinder bore. A discharge valve introduces a high pressure gas in the working chamber into the discharge chamber during a compression stroke. A crank chamber communicates to each of the cylinder bores at rear sides of the pistons. A swash plate is tiltably supported on a drive shaft and connected to each of the pistons through associated rods. The swash plate makes the pistons reciprocate in response to its undulating swing motion and varies its inclination angle based upon pressure differential between pressure in the suction chamber and pressure in the crank chamber therefore adjusting discharge displacement. A gas supply passage communicates each cylinder bore to the crank chamber in order to supply gas having a lower pressure than that in the working chamber at the time of completing the compression stroke. A gas bleed passage communicates the crank chamber to the suction chamber in order to introduce gas in the crank chamber into the suction chamber. A pressure control valve is provided in the gas supply passage or the gas bleed passage to control pressure of gas in the crank chamber. A valve is provided for opening and closing the gas supply passage in the middle of the compression stroke of each of the pistons.

摘要： To provide a piston compressor capable of preventing excessive oil from accumulating in a crank chamber in any operation state while securing the supply of oil to a swash plate. In a piston compressor in which an oil separation passage (43) is formed in a shaft (7) and a crank chamber (2) communicates with a suction chamber (31) through the oil separation passage (43), a supply passage (40) opens at a region of a cylinder block (1) opposed to a swash plate (18) to thereby allow a working fluid introduced from a discharge chamber (32) into the crank chamber (2) to be supplied to the swash plate (18) and a bypass passage (50) allowing the crank chamber (2) to constantly communicate with the suction chamber (31) is provided to thereby prevent the accumulation of excessive oil in the crank chamber (2) regardless of the operation condition. The bypass passage (50) communicates with the crank chamber (2) at a region positioned in the outer side of a rotation trajectory of the swash plate (18) in the radial direction.

摘要： A swashplate type variable-displacement compressor includes a compressor housing defining therein a crank chamber, a refrigerant suction chamber, a refrigerant discharge chamber, and a low-pressure refrigerant passage connected to an evaporator outlet, and a pressure regulator. The pressure regulator controls the amount of low-pressure refrigerant gas flowing into the refrigerant suction chamber by regulating a differential pressure between the pressure in the refrigerant suction chamber and the pressure in the crank chamber. The pressure regulator is comprised of a flow control valve including a first spring-loaded, normally-closed spool valve and a pressure chamber accumulating the working pressure used to force the spool valve toward its fully-opened position, and a flow control valve actuating mechanism including a communication passage through which the refrigerant discharge chamber is communicated with the pressure chamber, a second spring-loaded, normally-closed pilot valve provided in the communication passage, and an electromagnetic solenoid controlling the opening of the pilot valve so that the opening increases with an increase in exciting current supplied to the solenoid. The pilot valve serves to introduce high-pressure refrigerant gas in the refrigerant discharge chamber into the pressure chamber as the working pressure with the opening controlled by the solenoid.
