Fluid energy machine

from Wikipedia, the free encyclopedia

A fluid energy machine is a machine in which mechanical work is exchanged with a fluid , i.e. a gas or a liquid. The fluid energy machine either transfers the work from the outside to the fluid (work machine), or removes energy from the fluid (engine), which is then released to the outside as mechanical work . Thermal fluid energy machines are operated with compressible (gaseous) fluids, hydraulic ones with incompressible (mostly liquid) fluids.
