A variable geometry turbine having a wastegate includes a turbine housing, a power turbine, and a regulating valve. The turbine housing is provided with an inner intake gas flow channel and an outer intake gas flow channel. The turbine housing is further provided with a wastegate pipeline configured to bypass the power turbine, and a wastegate valve configured to control communication of the wastegate pipeline. One of the regulating valve and the wastegate valve has a regulating face having a varying axial height in a rotation direction of the regulating valve, and the other of the regulating valve and the wastegate valve has a linking portion which makes contact and cooperates with the regulating face. Thus, the efficiency of the turbine is improved significantly and backflow of the gas flow is reduced.

Variable geometry wastegate turbine

A variable geometry turbine (VGT) for turbochargers incorporates a turbine nozzle having a plurality of vanes, each vane having an airfoil with an inner disc and an outer disc. A first nozzle plate incorporates pockets to receive the inner discs with the inner discs substantially flush with a nozzle surface on the first nozzle plate. A second nozzle plate has pockets to receive the outer discs with outer discs substantially flush with a second nozzle surface. An integral actuation system rotates the plurality of vanes for variation of the nozzle geometry.
