Turbine wastegate

Abstract

A turbine housing assembly can include a turbine housing that includes an exterior surface, an interior surface that includes a wastegate seat, and a bore that extends between the interior surface and the exterior surface; a bushing disposed at least partially in the bore where the bushing includes a bushing bore; a wastegate that includes a shaft that extends through the bushing bore to a shaft end, a shaft shoulder disposed in the bushing bore, a plug, and an arm disposed between the shaft and the plug; a ring disposed at least in part in the bushing bore between the shaft shoulder and the shaft end; and a control arm connected to the shaft proximate to the shaft end to define an axial distance between a surface of the control arm and the shaft shoulder where the ring has an axial length that is less than the axial distance.
