20110072815 | Flow Control Device for a Turbocharger - A flow control device for a turbocharger ( | 03-31-2011 |
20160025044 | ASYMMETRIC DOUBLE-ENTRY TURBINE - An asymmetric double-entry turbine is provided with a turbine housing that includes a first volute, a second volute and a turbine receiving bore. The first volute has a first exhaust gas inlet and a first exhaust gas outlet. The second volute has a second exhaust gas inlet and a second exhaust gas outlet. The turbine receiving bore is in fluid communication with the first exhaust gas outlet and the second exhaust gas outlet for conducting a flow of exhaust gas from the first exhaust gas outlet and the second exhaust gas outlet out in an axial direction. The first exhaust gas outlet has an angular opening amount of more than 180 degrees around the turbine receiving bore. The second exhaust gas outlet has an angular opening amount of less than 180 degrees around the turbine receiving bore. | 01-28-2016 |

20100293942 | PASSIVELY CONTROLLED TURBOCHARGER - A flow control device for a turbocharger, the flow control device comprising a variably restricting flow restrictor for restricting flow in a turbocharger inlet by a variable amount, the flow control device being arranged such that the flow restrictor position varies flow restriction in response to force acting on a surface of the flow restrictor caused by a pressure pulse in a flow direction, the flow restrictor being biased in a direction opposed to the flow direction. | 11-25-2010 |

20160084156 | VARIABLE FLOW-RESTRICTING TURBINE ASSEMBLY FOR A TURBOCHARGER, CORRESPONDING TURBOCHARGER ENGINE AND VEHICLE, AND OPERATING METHOD - A variable flow-restricting turbine assembly for a turbocharger is disclosed. The assembly comprises a housing, a turbine mounted for rotation in the housing, and a variable flow-restrictor. The variable flow-restrictor comprises a first series of angularly-distributed flow-restrictor portions distributed around the turbine wheel and located in an exhaust flow path to the wheel, and a second series of angularly-distributed flow-restrictor portions distributed around the first series and located in the exhaust path. At least one of the first and second series is rotatable in the housing to vary the relative angular positions of the first and second series. The restrictor portions are arranged such that the first portions align with the second portions at each of a plurality of relative angular positions to open flow channels between the portions and such that they misalign between those positions to close the flow channels. | 03-24-2016 |
