    摘要: A suction throttle valve of a variable displacement compressor having a compressor housing includes a suction chamber, a crank chamber, an inlet, a suction passage, a valve body, a valve housing, an urging member, a valve chamber, and a communication hole. The valve body is provided for adjusting an opening area of the suction passage and movably arranged in the suction passage. The urging member urges the valve body in the direction that decreases the opening area of the suction passage. The communication hole is provided for connecting the suction chamber to the valve housing. An opening area of the communication hole is variable in accordance with the movement of the valve body. Accordingly, the opening area of the communication hole becomes maximum during the maximum displacement operation of the compressor and becomes reduced during the intermediate displacement operation of the compressor.

    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.
