  • Patent number: 4625509
    Abstract: A combustion engine has a plurality of equidistantly spaced jets disposed about a drive shaft. Fuel flows through the center of a two-piece drive shaft and combines with air in jets for combustion which is self-sustaining once ignited. Each of the jets is designed to accommodate water injection for vaporization to increase the exhaust thrust of the jets. In a further embodiment of the invention, a liquid flywheel comprises a lower tank disposed about a rotating vertically aligned shaft and contains a liquid which rises up tubes connecting the tank to an upper chamber. Fluid accumulating in the upper chamber acts as a momentum stabilizer to increase the efficiency of the engine. Vaporization water may be introduced into each of the plurality of jets disposed about the drive shaft by connecting lines which receive water from a source connected to an annular chamber in the two-piece drive shaft.

  • Patent number: 4484655
    Abstract: A gearless transmission providing pressurized hydraulic fluid to torque motors for driving a vehicle. A hydraulic pump is driven by a turbine engine shaft to provide fluid to accumulators and then to the transmission device. Fluid is selectively admitted into the transmission by the vehicle accelerator pedal. Thereafter the fluid flow may be restricted through fluid circuitry having orifices which provide variable torque output. The circuitry is controlled by a shifter selector with pilot lines to actuate fluid control valves between two control positions. Especially important for turbine-powered vehicles, the transmission provides a braking function when the accelerator pedal is released in either the low or second control range of operation. Means for providing a reverse mode of operation is also disclosed.
