<p>A transducer includes a linear input power source (12) connected to a connecting rod (24) in turn connected to output drive shafts (30 & 36) through one-way clutches (28 & 40), with the output drive shafts being interconnected through gears (32 & 40) such that when one shaft is powered, the other is coasting. The power source includes multiple stern powered cylinders (16 & 94). Inlet and outlet valves (44) for each cylinder chamber are controlled by an actuator (56) which instantaneously snaps the valves between open and closed positions. The power cylinders (16 & 94) may be operated individually, in parallel or in series and as required, a valve passageway through the piston (18) may be operated to equalize pressure. A pair of O-rings (121) on the piston (18) engage the cylinder wall only when the adjacent chamber is pressurized, thereby reducing drag in operation of the piston.</p> |
