ABSTRACT:
Multiple steam powered cylinders reciprocate to pivot arms back and forth connected to output drive shafts through one way clutches with the output drive shafts being interconnected through gears such that when one shaft is powered, the other is coasting. The inlet and outlet valves for each cylinder chamber are controlled by an actuator which instantaneously snaps the valves between open and closed positions. The power cylinders may be operated individually, in parallel or in series and as required, a valve passageway through the piston may be operated to equalize pressure. A pair of O-rings on the piston engage the cylinder wall only when the adjacent chamber is pressurized, thereby reducing drag in operation of the piston.
