VARIABLE DISPLACEMENT SWASH PLATE TYPE COMPRESSOR AND AIR CONDITIONER SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a variable displacement swash plate type compressor wherein it is possible to prevent decreases in performance caused by restricting a suction path in an operating area in which low pressure pulsation does not occur, and to sufficiently reduce low pressure pulsation by restricting a suction path in an operating area that is prone to the occurrence of low pressure pulsation, and an air conditioner system using the compressor.SOLUTION: This variable displacement swash plate type compressor 4 is provided with: a suction throttle valve 62 that is disposed in a suction path 61 for guiding a coolant that has been sucked from a suction inlet 60 to a suction chamber 54 and that adjusts the path area for the coolant that passes through the suction path 61; and a solenoid valve 70 that arbitrarily adjusts the aperture of the suction throttle valve 62. The solenoid valve 70 may be one that adjusts the aperture of the suction throttle valve 62 by regulating the pressure in a back pressure chamber 68 of the suction throttle valve 62 or one that directly controls the aperture of the suction throttle valve 62 depending on the applied electric energy.
