ABSTRACT:
A steam engine wherein the inlet and relief valves are subjected to balanced stresses and the pressure of steam is maintained above the critical point. The engine can be braked electrically, mechanically and with steam; the braking with steam takes place subsequent to the application of electrical and mechanical brakes. The engine is equipped with arrangements for venting the steam path prior to starting, for replenishing the supply of fluid in order to compensate for leakage through the valves and/or from the engine cylinders, and with a control system which partly opens the relief valves and closes the inlet valves in response to actuation of the steam brake.
