the engine has a pressure level provided by an external source of pressure.

摘要

the invention relates to an engine (20) is driven by a pressure agent provided by an external source of pressure. a rotor (28) to form a tight abutment against a local area (21d) of the cylindrical inner wall (21c) of the engine (20).a forming plate (30) is mounted to the piston at one end of the rotating rotor (28) and can be rotated towards the front and towards the rear of the working chamber (21) of the engine compartment of the boat relative to the rotor (28).at the same time, at the opposite end of the piston forming part of the plate (30) is a tight abutment wall (21c) of the inner circular chamber (26) of the engine.
