Abstract
The present invention relates to external combustion engines and more precisely to motors using the Stirling cycle designed to directly convert thermal energy into electrical energy. In accordance with the invention, this transformation is carried out inside a machine which is completely sealed, without a mechanical connection with the outside, in which the power piston drives the moveable part of an electrical generator. In accordance with one preferred embodiment, this electrical generator is a linear alternator. In accordance with a further original feature of the invention, control of the coupling between the displacing piston and the power piston is carried out by using electronic regulation.
