Abstract

A turbocharger has a variable geometry turbine (1) of the swing vane kind. The vanes (24) are pivotally mounted on a vane carrier (23) and extend into an annular passageway (13) defined between a first surface (21) of the vane carrier and the turbine housing or the bearing housing. The carrier has a second surface (28) that is connected to a supporting wall (30) of the bearing housing (3) or the turbine housing (4) by means of a plurality of substantially radially extending key connections (41,43). These resist the rotational force applied to the carrier by the passage of the exhaust gas over the vanes and also permit thermal expansion of the vane carrier (23) relative to the supporting wall.
