Abstract
A variable geometry turbine has a housing for receipt of the turbine wheel. A gas flow control mechanism in the housing upstream of said turbine wheel is operable to control gas flow through a gas flow inlet passage. The control mechanism has a movable nozzle ring or shroud for varying the size of the gas flow inlet passage. A transmission mechanism for connection between an actuator and the control mechanism converts movement applied by the actuator into movement shroud or nozzle ring. The transmission mechanism comprises a yoke having a shaft that is rotatably supported by a wall of the housing. The yoke defines arms that extend outwardly of the shaft and which engage with the shroud or nozzle ring. There is provided at least one recess defined in an inside surface of the housing, the recess extending from shaft rotation axis and configured to allow passage of an end of the yoke shaft along it during insertion of the yoke into the housing.
