摘要

The engine (1) has a cylinder (2) defining an internal chamber within which a piston is slidable. A high temperature heat exchanger (3) is arranged in the engine, and a high temperature pipe (4) connects the heat exchanger with the chamber. A high temperature valve (5) is arranged at an end of the high temperature pipe. The valve is movable in translation along a valve axis (35) between a closed position and an open position. A total or variable deactivation unit is arranged in a control device of the valve.
