A volumetric expander (4) comprising a casing (50) having a general inlet and outlet (51, 52), a piston (6) operating inside the casing and adapted to define an expansion chamber (7) with variable volume, a main shaft (11) connected to the piston (6), and a valve (6) for selectively opening and closing an inlet and an outlet (8, 9) of the expansion chamber (7) allowing: a condition of introduction of the working fluid in the expansion chamber (7), a condition of expansion of the working fluid in the expansion chamber (7), and a condition of discharge of the working fluid from said expansion chamber (7). The expander comprises a transmission member (53) connectedon one sideto the valve (10) andon the other sideto the main shaft (11). The casing (50) defines a discharge chamber in direct communication with the general outlet (52) and configured for being put in direct fluid communication with the outlet (9) of the expansion chamber (7) during the condition of discharging the working fluid from the expansion chamber (7) itself. The transmission member (53) is disposed in the casing (50) inside the working fluid discharge chamber. The casing (50) comprises an auxiliary inlet (59) which is only directly in communication with the discharge chamber of the casing (50) and through this latter, with the general outlet (52); the auxiliary inlet (59) is configured for enabling the working fluid to directly enter the casing (50).

A high efficiency uniflow steam engine having automatic poppet valves yieldably based by fluid such as steam held under pressure within a cavity in the engine and a cutoff control for closing a steam inlet valve at any time selected stops the flow of steam into the cylinder. Proximate the end of the exhaust stroke, around 0.12 inch before TDC the cylinder is sealed to thereby compress residual steam as the piston clearance approaches zero; typically, 0.020 inch which raises cylinder pressure enough to open an inlet valve without making physical contact to push the inlet valve open with the piston thereby eliminating a tappet type of noise, shock and wear.

A steam reciprocating piston engine that uses a pressurized working fluid to drive first and second pistons in reciprocating power strokes is disclosed. A piston is configured for reciprocating motion within the cylinder and traverses between bottom dead center and top dead center positions. An uppermost stop is reached wherein the working fluid is allowed to escape the cylinder through one or more exhaust ports whereby the fluid travels through a closed loop circuit ultimately directing pressurized fluid back into the cylinder inlet. Momentum causes a spring connected mass to continue upward maintaining the piston above the exhaust port so as to allow escape of the working fluid. Return of the piston and mass is caused by opposite movement of a second piston whereby another stroke is initiated. Power output may be transferred to any suitable system.

An engine and corresponding driving propulsion system may provide continuous force necessary to keep the engine operating. Utilizing two pressurized tanks with high and low pressures may provide a continuous flow of pressure to the engine necessary for it to operate.
