活塞型
使气体在可变容积中膨胀，输出外功制冷的膨胀机(通常由电动机制动吸收外功)。这种膨胀机分立式和卧式两种。采用较多的是立式结构，曲轴、连杆、十字头、活塞、进气和排气阀等是运动件，分别装在机身、气缸和中间座中，其作用近似于往复活塞压缩机，但其进、排气阀系借进、排气凸轮定时启闭。
透平型
透平型膨胀机原理图
以气体胀时速度能的变化来传递能量的膨胀机。这种膨胀机有单级和双级、立式和卧式、冲动式和反动式之分。一般采用单级向心径流反动式，传出的外功由发电机、鼓风机或油制动器所吸收它近似于单级离心压缩机，但具有调节进气量用的(可调叶片)导流器。低速油承用油强制润滑，高速的采用气体轴承。

Piston type
An expander that causes gas to expand in a variable volume to output external work for cooling (usually absorbed by motor braking). The expansion machine is divided into vertical and horizontal two kinds. The most used is vertical structure, crankshaft, connecting rod, cross head, piston, intake and exhaust valves are moving parts, respectively installed in the body, cylinder and middle seat, its role is similar to reciprocating piston compressor, but its inlet and exhaust valves are timed to open and close by the inlet and exhaust CAM.
Turbine type
Schematic diagram of turbo-type expansion machine
An expander that transmits energy through changes in velocity energy during gas expansion. The expander is divided into single stage and double stage, vertical and horizontal, impulse and reaction type. Generally, single-stage radial flow reaction type is used, and the outgoing external work is absorbed by the generator, blower or oil brake. It is similar to a single-stage centrifugal compressor, but has a (adjustable blade) deflector for regulating the intake volume. Low speed oil bearing oil forced lubrication, high speed gas bearing.
