Robert Stirling patented his air engine in 1816, describing a closed-cycle heat engine and an 'economiser' heat exchanger.
The patent described a closed-cycle air engine, differing from Cayley's open-circuit design. It included a heat exchanger called an 'economiser,' which stored heat from the working gas during one part of the cycle and returned it during another, later becoming known as the regenerator.
