摘要： A variable displacement compressor includes a housing, a rotary shaft, a swash plate, a suction pressure region, a suction throttle valve, an oil reservoir, a lubricating oil passage, a gas flow passage, a communication passage, and a throttle mechanism. The suction-pressure region includes a suction chamber and a suction passage. The suction throttle valve is arranged in the suction passage and defines an upstream suction-pressure region and a downstream suction-pressure region. The lubricating oil passage connects the oil reservoir to the upstream suction-pressure region. The gas flow passage connects the crank chamber to the suction chamber. The communication passage connects the lubricating oil passage to at least one of the downstream suction-pressure region, the gas flow passage and the crank chamber. The throttle mechanism is provided in the lubricating oil passage between the oil reservoir and a position where the communication passage connects to the lubricating oil passage.

摘要： The present invention is directed to provide a device for reducing pulsation in a variable displacement compressor. The compressor is connected to an external refrigerant circuit. The device for reducing pulsation includes a flow passage and a control valve. The control valve includes a valve housing, a spool valve and a damper chamber. The spool valve has formed therethrough a flow hole. The damper chamber communicates with the flow passage adjacent to the external refrigerant circuit through the flow hole. Effective cross-sectional area and effective length of the flow hole are determined based on frequency of a specific pulsation of the refrigerant gas and volume of the damper chamber at the time of the development of the specific pulsation in such a manner that the specific pulsation is developed, resonance effect of a Helmholtz resonator takes place in the damper chamber.
