  • Variable geometry turbocharger with sliding piston
    Patent number: 7024855
    Abstract: A turbocharger having a variable geometry turbine inlet incorporates a piston movable to vary the area of the inlet nozzle into the turbine. Vanes extending from the heat shield for flow control in the nozzle are engaged by the piston in a first closed position. In a second open position, the piston is spaced from the vanes increasing the inlet nozzle area.

  • Variable geometry turbocharger with sliding piston
    Publication number: 20040025504
    Abstract: The invention concerns a turbocharger with a variable geometry turbine comprising a mobile cylindrical piston (70) to modify the cross-section of the input nozzle to the turbine. Vanes (90) extending from a heat shield (92) for adjusting the flow of the nozzle are contacted by the piston in a first closed position. In a second open position, the piston is spaced apart from the vanes, thereby increasing the input nozzle cross-section.
