Abstract

Abstract A hydrostatic drive system generally of the type wherein vapor is alternately directed into one of two reservoir tanks so that working fluid in that tank is forced out of the tank by pressure of the vapor and through a fluidic motor to generate a mechanical output before it returns to refill the other tank. When the first tank is substantially depleted, the vapor pressure is directed into the refilled tank so that fluid from that tank now flows through the moter to refill the first, now depleted, tank. In one embodiment, cyclic pressure generated by a vapor generator forces fluid cyclically through an AC fluid motor. In another embodiment, heat from the working fluid is employed to generate the vapor pressure and reduce the temperature of the working fluid passing through the motor. In a further embodiment, the fuel serves as the working fluid and the vapor from the refilling tank is combusted to provide heat to convert the fuel from its liquid to vapor state. In another embodiment, the combustion gases are combined with the vapor so that, when water is the working fluid, the water vapor in the combustion gases serves as make up working fluid. In a further embodiment, heat from working fluid on its way to the motor is transferred to other working fluid in a second system to drive a second motor. Further aspects of the invention are set forth below.
