Heat Engine

Abstract

A heat engine comprises a first displacing piston and a second displacing piston, wherein a surface of the first displacing piston and a surface of the second displacing piston that face each other limit a working space that is filled with a working gas. The two heat exchanger arrangements are arranged in the working space between the first displacing piston and the second displacing piston, each heat exchanger arrangement comprising a heat source and a heat sink. The working gas flows through or circulates around each of the two heat exchanger arrangements. The first displacing piston, and the second displacing piston, and/or the heat exchanger arrangements are rotatably mounted with respect to an axis. Measures are provided for counteracting against a circular motion of the working gas around the axis relative to the heat exchanger arrangements.
