摘要： A variable capacity type vane compressor comprising a cylinder having an oblong cylinder bore and a rotor with radial vanes rotatably inserted in the cylinder so that the radially outer ends of the vanes are in slidable contact with the cylinder bore surface to form compression chambers therebetween. A movable capacity control disk is arranged at an interface between one side plate and the rotor to control the quantity of introduced gas and/or returned compressed gas to vary a capacity of the compressor. The capacity control disk is moved by a spool actuator inserted in a spool cylinder having opposed working chambers. Gas under output pressure is introduced into the first working chamber, and oil under output pressure is introduced into the second working chamber, while a leak passage relieves the oil pressure to an intermediate pressure. A spring is also arranged in the second working chamber to urge the spool, and a valve is arranged in the oil passage close to the second working chamber to regulate the movement of the spool in response to a predetermined requirement.
摘要翻译：一种可变容量型叶片压缩机，包括具有长圆筒孔的圆筒和具有可旋转地插入圆筒中的径向叶片的转子，使得叶片的径向外端能够与气缸孔表面滑动接触以在其间形成压缩室。可移动容量控制盘布置在一个侧板和转子之间的界面处，以控制引入的气体和/或返回的压缩气体的量以改变压缩机的容量。容量控制盘通过插入在具有相对的工作室的卷轴筒中的卷轴致动器移动。输出压力下的气体被引入第一工作室，输出压力下的油被引入第二工作室，而泄漏通道将油压减轻到中间压力。弹簧还布置在第二工作室中以推动阀芯，并且阀在靠近第二工作室的油通道中布置，以响应于预定要求来调节阀芯的运动。
