  • Patent number: 6905322
    Abstract: A motor for converting fluid pressure to rotational motivation, and pump for moving fluid, is provided. The motor/pump includes a drum provided within a cylindrical cavity defined by a housing. Vane assemblies are provided which extend through the inner drum, and are actuated to extend and retract through their operable coupling to a cam provided within the inner drum. As the inner drum rotates, the vanes extend and retract, alternately increasing and decreasing their drag coefficient, causing pressurized fluid admitted into the interior to drive the vanes and inner drum in a single direction. Alternatively, a power source may be coupled to the motor to drive the motor, thereby causing it to act as a pump for moving fluid from one location to another.

  • Patent number: 6616433
    Abstract: A motor for converting fluid pressure to rotational motivation and pump for moving fluid, comprising an outer race centered about a first axis and an inner race centered about a second axis. The first axis is different from, but parallel to, the second axis. A plurality of vanes is coupled for movement relative to the inner race and a fluid is provided into the vane at a pressure sufficient to cause the vane to rotationally drive the inner race relative to the outer race. Alternatively, the inner race may be driven directly to pump fluid between the inner race and the outer race.

  • Patent number: 6453793
    Abstract: A motor comprising a shaft with four racks which translate linear actuation of the racks to rotational motion of the shaft through pinions secured to sprag clutch assemblies. Motion of the rack assemblies is preferably offset to maintain a substantially constant rotation of the shaft during operation of the motor. The motor uses a pair of primary fluid expansion chambers to generate linear actuation of a first pair of racks, and a pair of secondary expansion chambers to generate linear actuation of the remaining racks.

  • Patent number: 6308611
    Abstract: A fluid valve system is provided for a variable stroke motor. The valve has a housing forming a cylinder, a first fluid input into the cylinder, a first fluid output out of the cylinder, a second fluid input into the cylinder, and a second fluid output out of the cylinder. Provided within the cylinder is a shaft provided with slots. As the shaft rotates into a first position, fluid communication between the first fluid input and the first fluid output is shut off, while fluid communication between the second fluid input and second fluid output is opened. As the shaft rotates to a second position, communication between the first fluid input and first fluid output is opened, while the communication between the second fluid input and the second fluid output is shut off. The device is preferably hooked up to a drive cylinder in fluid communication with the first fluid output and the second fluid input. A piston is provided within the drive cylinder.

  • Patent number: 5461863
    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.

  • Patent number: 5381760
    Abstract: High pressure air on the order of 3,000 PSI is injected into the combustion chamber of an internal combustion engine during only the combustion cycle of engine operation to increase its horsepower and torque. The injection of air is triggered by the combustion chamber pressure reaching a predetermined level which causes a check valve to be opened thereby providing communication from an air source to the combustion chamber. When the combustion chamber pressure drops to a predetermined level, spring biased pressure combined with air injection pressure will exceed combustion pressure and cause the ball valve to return to its closed position. The cycle will be repeated during each combustion cycle of operation of a multiple cycle engine.

  • Patent number: 4215674
    Abstract: A radiant electromagnetic energy collector has an elongated non-imaging concentrator which concentrates and directs radiant energy onto an elongated absorber having a helical conduit for a heat exchange fluid mounted in an evacuated glass tube. The concentrator has rounded ends which also function as concentrating surfaces to concentrate and direct radiant energy onto the ends of the absorber. The helical conduit within the evacuated tube is connected to input and output pipes leading to the exterior of the tube which pass through a seal situated within the cylinder formed by the helical coil. The collector has a flexible transparent cover which is stretched to a flat sheet and held in position by an interengaging channel and locking rod arrangement located about the periphery of the concentrator.
