Abstract
A closed cycle regenerative heat engine has a housing defining a chamber. A displacer is housed in the chamber. A power piston is housed in the chamber. The displacer is resiliently deformable from a rest condition in response to displace the working fluid in the chamber. The displacer may be a multi-start volute spring. The displacer may be provided with a heat storage reservoir to store heat received from a working fluid as the working fluid is displaced from a heating location in the chamber to a cooling location in the chamber and reject heat to the working fluid when the working fluid is displaced from the cooling location to the heating location. The resiliently deformable displacer may comprise two components with an air space defined between the two components.
