Abstract
The present invention relates to a volumetric heat engine with a cycle derived from the Stirling cycle, or designed as an internal combustion engine. A pendulum-piston is mounted in a closed casing of almost parallelepiped shape to define at least one chamber there between. The piston pivots about an axis with a reciprocating rotary movement. The piston can be freely movable without any return spring. In the case of a Stirling cycle, the piston acts as both displacing piston and working piston. Cold and hot sources are located at opposite ends of the casing. In the case of an internal combustion engine, the heat engine is capable of operating in a two-stroke combustion cycle with uniflow scavenging of the gases burned by the air/fuel mixture.

1-12. (canceled)
A pendulum-piston machine for production of mechanical work or cooling using a working fluid, the machine comprising:
- a main shaft defining a main axis thereof;
- a piston connected to the main shaft and having a reciprocating movement around the main axis;
- the piston having a plate connecting to the main shaft and extending in a plane generally parallel to the main axis, the plate having sides edges being opposite to one another relative to the main axis;
- a casing receiving the piston therein and the main shaft extending therethrough, the casing having a side wall generally extending around the main axis and defining two side wall surfaces thereof opposite one another relative to the main axis, the two side wall surfaces having a generally concave revolution shape centered about the main axis, each said side edge being adapted to be adjacent and slide along a respective said side wall surface during the reciprocating movement of the piston;
- wherein the piston and the casing defining at least one working chamber there between on one side of the piston and fillable with the working fluid, the machine having a geometric asymmetry to allow a volume of the working chamber to vary during the reciprocating movement of the piston within the casing.
