Rotary piston steam engine that comprises the expansion of the second with no back pressure in the expansion and the first balanced rotation variable intake cut-off valve

摘要

Rotary piston steam engine which includes a balanced double rotary piston is provided so as to provide a rotary variable intake cut-off valve which is balanced in order to improve their efficiency. Exhaust steam from the initial expansion is guided to the expansion of the second so as to prevent back pressure for further efficiency. Rotating valve, to balance the inlet and outlet both faces. When the rear surface of the rotary piston to pass through the inlet port of the housing of the expansion chamber, the exhaust steam from the expansion of the initial is removed, the expansion of the second exhaust outlet, expansion inlet initial curved portion of the housing of the expansion chamber Located at about 180 degrees from, the back pressure is not applied to the initial expansion.
