　　常用的空气压缩机有活塞式空气压缩机，螺杆式空气压缩机，(螺杆空气压缩机又分为双螺杆空气压缩机和单螺杆空气压缩机)，离心式压缩机以及滑片式空气压缩机，涡旋式空气压缩机。凸轮式，膜片式和扩散泵等压缩机没有列入其中，是因为它们用途特殊而尺寸相对较小。

　　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。

　　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。The commonly used air compressors include piston air compressors, screw air compressors (screw air compressors are further divided into twin-screw air compressors and single screw air compressors), centrifugal compressors, sliding vane air compressors, and scroll air compressors. Compressors such as cam type, diaphragm type, and diffusion pump are not included because they have special applications and relatively small sizes.

　　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
