Definition

A Stirling engine is a mechanical device which operates on a closed regenerative thermodynamic cycle, with cyclic compression and expansion of the working fluid at different temperature levels. The flow is controlled by volume changes, and there is a net conversion of heat to work or vice versa.

This generalized definition embraces a large family of machines with different functions, characteristics, and configurations. It includes both rotary arid reciprocating machines, utilizing mechanisms of varying complexity. It covers machines capable of operating as prime movers, heat pumps, refrigerating engines, or pressure generators.

Other machines exist which operate on an open regenerative cycle, where the flow of working fluid is controlled by valves. For convenience, these may be called Ericsson engines. Unfortunately the distinction is not widely established in practice and the name 'Stirling engine' is frequently indiscriminately applied to all types of regenerative machines.
