Abstract
A variable geometry turbine has a gas flow control mechanism located upstream of the turbine wheel and operable by an actuator assembly to control gas flow through said inlet passage. The control mechanism comprises a movable member for varying the size of the inlet passage. The movable member is coupled to a pair of rods that translate in an axial direction. The rods are supported for translation in guide bushes. A seal assembly seals against each rod and comprises a seal carrier coupled to an end of the guide bush. The seal carrier carries a lip seal that is in sealing contact with an external surface of the rod.
