  • Variable displacement turbocharger
    Patent number: 4741666
    Abstract: A turbine casing, a shroud and a gas outlet cover together define a closed doughnut-shaped space. A nozzle driving ring inserted in the space is slidably clamped by the turbine casing and the gas outlet cover. Nozzle shafts extending from nozzle blades are connected through links to the nozzle driving ring. The nozzle driving ring can be driven from outside the space. The nozzle driving ring for simultaneously varying the angle of the nozzle blades is restrained in the axial direction effectively with a high degree of accuracy.
