Variable geometry wastegate turbine
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.
