  • Patent number: 8800286
    Abstract: The invention comprises a rotary engine method and apparatus configured with an exhaust system. The exhaust system includes an exhaust cut or exhaust channel into one or more of a housing or an endplate of the rotary engine, which interrupts the seal surface of the expansion chamber housing. The exhaust cut directs spent fuel from the rotary engine fuel expansion/compression chamber out of the rotary engine either directly or via an optional exhaust port and/or exhaust booster. The exhaust system vents fuel to atmosphere or into a condenser for recirculating of fuel in a closed-loop circulating rotary engine system. Exhausting the engine reduces back pressure on the rotary engine thereby enhancing rotary engine efficiency.

  • Patent number: 8636467
    Abstract: A variable geometry turbine of the kind used in a turbocharger has a variable geometry element such as a nozzle ring that is operated by an actuator. The actuator comprises a motor which drives a cross-shaft in rotation. The cross-shaft in turn drives a pair of guide rods on which the nozzle ring is supported in translation so as to move the nozzle ring and control the width of the inlet passage of the turbine. The cross-shaft and guide rods are drivingly engaged by a rack and pinion or thread or another toothed or threaded formation suitable for converting rotational movement into translational movement. The cross-shaft can be located in close proximity to the guide rods and the output of the motor shaft so as to provide a compact package. Moreover, the torque required to resist movement of the nozzle ring in operation is much reduced in comparison to existing designs.

  • Publication number: 20130078083
    Abstract: A variable nozzle for a turbocharger includes a plurality of vanes rotatably mounted on a nozzle ring and disposed in a nozzle flow path defined between the nozzle ring and an opposite nozzle wall. Either or both of the faces of the nozzle ring and nozzle wall include(s) grooves extending substantially transverse to a general flow direction of the flow through the nozzle, and there are clearances between the ends of the vanes and the adjacent faces. Leakage flow through the clearance between the end of each vane and the adjacent face having the grooves must proceed across the grooves, and thus a labyrinthine flow passage is presented to the leakage flow. The labyrinthine passage has a greater resistance to flow than would be the case without the grooves. Accordingly, leakage flow is reduced, which is beneficial to turbine efficiency.

The velocity of the mixture is less than that of the primary fluid, while the mass flow of the mixture is approximately equal to the sum of the mass flows of the primary and secondary fluids. The regulator compares the rotational speed of the turbine to a target speed and regulates parameters associated with the turbine device if the rotational speed of the turbine and the target speed differ by more than a predetermined amount.

The rod has a nozzle directing a jet of air onto the blades to turn the rotor. The rod is movable axially so that when it is desired to stop the rotor the free end of the rotor engages an annular surface of the rotor to exert a braking force thereon. The rod moves under the action of a spring. Air to the nozzle is supplied through a hand-operated valve and the air supply is taken through a cylinder having a piston connected to the rod. The arrangement is such that when the valve is opened to feed the nozzle and turn the rotor, the air pressure moved the piston in the sense of retracting the rod from the braking position.
