ABSTRACT:
There is described a variable geometry turbine having a sliding element (5) for the control of the section throat of the turbine (1) by sliding movement along an axial direction of a turbine wheel (71). The turbine wheel operates to convert a flow of working fluid into mechanical energy. At least one bypass channel (51) is defined in the sliding element (5). The bypass channel is further connected to a turbine wheel outlet area (79) downstream of the turbine wheel for selectively guiding an excess flow of working fluid past the turbine wheel (71), so as to control the operation of the turbine. A use of the variable geometry turbine with a turbocharger for an engine and a method for controlling such turbine is also described.
