Abstract
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.
