  • Wastegate valve for turbocharger
    Patent number: 5046317
    Abstract: A twin wastegate valve for an exhaust gas driven turbocharger in which exhaust gas is communicated to the turbine wheel through separate inlet passages includes a pair of wastegate valve members mounted for pivoting movement relative to a support. The support is pivotally mounted on the actuating arm. Accordingly, small differences in the height of the valve seat caused by wear or by manufacturing tolerances do not affect closure of the valve.
