| description | A turbine comprises a turbine housing defining a turbine inlet upstream of a turbine wheel and a turbine outlet downstream of the turbine wheel; and a wastegate valve assembly comprising at least one movable valve member mounted on a movable support member within a wastegate chamber which communicates with the turbine inlet upstream of the turbine, and has one or more chamber outlets which communicate with an outlet of the turbine. The valve member is permitted to articulate slightly about the support member, with the amount of articulation being limited by collisions between respective limit areas on a rear surface of a sealing portion of the valve member and a front surface of the support member. Each valve member is connected to the support member using a pin portion of the valve member which passes through a washer with a non-circular outer profile, and rotation of the washer is limited by contact surfaces of the support member. |
