Abstract: A turbine for a turbo-machine is proposed in which, at a gas inlet for a turbine wheel, vanes extend from a nozzle ring though slots in a shroud. The nozzle ring and shroud are relatively rotatable about a rotational axis of the turbine by at least 0.1 degrees. In use, the nozzle ring and shroud are relatively rotated to bring one side of the vane into close contact with one surface of the slot, to inhibit leakage of gas between the vane and the slot surface. For this purpose the respective surfaces of the nozzle and slot can be configured to closely conform to each other. If there is differential thermal expansion of the shroud and nozzle ring, the nozzle ring and shroud can relatively rotate, to withdraw the vane from the edge of the slot to relieve the pressure between them.

Abstract: A steam valve having a first inclined surface, which is formed at the distal end portion of a valve rod and in which the outer diameter of the valve rod increases from the distal end toward the base end of the valve rod, and a second inclined surface, which is formed on the inside of a portion of a main valve that is positioned on the base-end side of the valve rod and which inclines with the same inclination angle as the first inclined surface. In a state in which a slave valve and the main valve are closed the first inclined surface and the second inclined surface are separated from each other, and when the slave valve and the main valve are in a fully open state the first inclined surface and the second inclined surface abut each other.

Abstract: The invention relates to a flap arrangement for a turbine of a turbocharger, in particular for a wastegate valve of the turbine, having a spindle for mounting the flap arrangement in a rotatable manner in a turbine housing, having a lever arm, wherein the lever arm is coupled to the spindle, and having a flap disk, wherein the flap disk is coupled to the lever arm. At least part of the lever arm is configured elastically such that applying a closing force to the flap arrangement, when the flap disk is in contact with a flap seat in the turbine housing, provides for relative movement of the flap disk in relation to the spindle, in order to compensate for thermal deformation of the turbine housing and/or wear.

Abstract: An exhaust manifold for an internal combustion engine is provided. The manifold comprises at least one first exhaust gas inlet connectable to a first bank of cylinders of the engine, and at least one second exhaust gas inlet connectable to a second bank of cylinders of the engine. First and second exhaust gas outlets are connectable to respective first and second volutes of a twin volute turbocharger. At least one wastegate outlet is connectable to a bypass passage which bypasses the turbocharger. A diverter valve is located within the manifold, wherein the diverter valve is adapted to selectively direct exhaust gas from the first and second inlets to at least one of the first and second exhaust gas outlets and the wastegate outlet. A turbocharger is also provided having the same diverter valve arrangement, as are internal combustion engines having either the manifold or turbocharger, and a vehicle having such an internal combustion engine.

Abstract: A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. Movement of the inlet-adjustment mechanism from the open position to the closed position is effective to shift the compressor's surge line to lower flow rates. The compressor includes a diffuser extending between an exducer of the compressor wheel and a volute for collecting pressurized air from the compressor. The diffuser is defined between first and second walls that diverge from each other in a radially outwardly direction through the diffuser. The divergent-wall diffuser enhances the shift of the surge line to lower flow rates when the inlet-adjustment mechanism is put in the closed position.
