Abstract

A variable geometry turbine of the kind used in a turbocharger has a variable geometry element, such as a nozzle ring mounted on guide rods 126, which is operated by an actuator. The actuator comprises a yoke defining a pair of arms 132 which extend into engagement with the guide rods. The actuator further comprises a motor to drive a toothed gear wheel 137 which is operatively connected to a sector gear 136 fixedly mounted on the yoke. The sector gear is defined by a rim that extends radially from the yoke pivot axis to one side of a plane which extends substantially parallel to the turbine axis and which contains the yoke pivot axis, and the arms of the yoke extend to the other side of said plane. Operation of the motor drives rotation of the yoke via the gears, which in turn drives the guide rods in translation.
