  • Turbine of a turbocharger
    Patent number: 8197194
    Abstract: A turbine of a turbocharger having a floating insert which defines a nozzle for passing a fluid and that is supported axially slidable with respect to a housing by a sliding support. The turbine includes a gas shielding for preventing a flow of fluid from impinging on the sliding support.

  • Variable geometry turbine for a turbocharger and method of controlling the turbine
    Patent number: 8047772
    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.
