　　容积式压缩机--直接依靠改变气体容积来提高气体压力的压缩机。

　　往复式压缩机--是容积式压缩机，其压缩元件是一个活塞，在气缸内作往复运动。Positive displacement compressor - a compressor that directly relies on changing the gas volume to increase gas pressure.

　　Reciprocating compressor - is a positive displacement compressor, whose compression element is a piston that moves back and forth in a cylinder.

　　Rotary compressor - is a positive displacement compressor, compression is achieved by the forced movement of rotating elements.

　　Sliding vane compressor - is a rotary variable capacity compressor, in which the axial sliding vane slides radially on the rotor eccentric to the cylindrical cylinder body. The air trapped between the slides is compressed and discharged.

　　回转式压缩机--是容积式压缩机，压缩是由旋转元件的强制运动实现的。

　　滑片式压缩机--是回转式变容压缩机，其轴向滑片在同圆柱缸体偏心的转子上作径向滑动。截留于滑片之间的空气被压缩后排出。
