VARIABLE GEOMETRY TURBINE WITH WASTEGATE |
摘要 |
A variable geometry turbine comprises a turbine wheel (5) supported in a housing for rotation about a turbine axis with an annular inlet passageway (9) defined between a radial face of a nozzle ring (11) and a facing wall of the housing (10). The nozzle ring is movable along the turbine axis to vary the width of the inlet passageway and has a circumferential array of vanes (20) that are received in corresponding slots (24) in the facing wall. A wastegate valve (15) is provided in a chamber behind the facing wall and gas bypasses the turbine through the chamber to the wastegate port (14) at high flow rates.
