VARIABLE DISPLACEMENT SWASH PLATE-TYPE COMPRESSOR AND AIR CONDITIONING SYSTEM USING SAID COMPRESSOR

摘要

Disclosed is 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. Also disclosed is an air conditioning system that uses said compressor. The variable displacement swash plate-type compressor is provided with: a suction throttle valve (62) that is disposed in a suction path (61) for guiding a coolant that was sucked from a suction inlet (60) to a suction chamber (54) and that adjusts the path size for the coolant that passes through said suction path (61); and a solenoid valve (70) that arbitrarily adjusts the aperture of said 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.
