    • 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.
    • 具有压缩机壳体的可变排量压缩机的抽吸节流阀包括抽吸室,曲柄室,入口,吸入通道,阀体,阀壳体,推动构件,阀室和连通孔。 阀体设置用于调节吸入通道的开口面积并可移动地布置在吸入通道中。 推动构件沿着减小吸入通道的开口面积的方向推压阀体。 连通孔用于将抽吸室连接到阀壳体。 连通孔的开口面积根据阀体的移动而变化。 因此,在压缩机的最大排量操作期间,连通孔的开口面积变得最大,并且在压缩机的中间位移操作期间减小。
