  • Publication number: 20140286758
    Abstract: A segmented nozzle ring is disclosed having a throat area between neighboring vanes that is the same for each segment which is achieved by rotation (i.e., opening or closing of the throat area) of the individual vane compounds belonging to the different segments. The resulting uniform throat area leads to a uniform exit flow angle of the nozzle and a uniform inlet flow angle of the rotor. As a result, high-cycle fatigue excitations of the rotor caused by the non-uniform flow can be eliminated, the thermodynamic efficiency of the turbine stage can be improved, and the nozzle ring need not be arranged in a fixed position relative to the gas inlet casing.

  • Patent number: 8517679
    Abstract: The piston ring sealing points of a sealing apparatus between the rotor and the housing of a continuous-flow machine each have a piston ring, a cylindrical contact surface, which is directed radially inward, on the housing, as well as an axial stop on the rotor. In this case, the piston ring of the outer piston ring sealing point has a larger external radius and a smaller internal radius than the piston ring of the inner piston ring sealing point. At the same time, the outer piston ring sealing point has a smaller internal radius than the inner piston ring sealing point. Because of the V-shaped arrangement concept, there is no need for a steel ring, shrunk onto the rotor, between the piston ring sealing points.

  • Publication number: 20120128479
    Abstract: The guide device for the diffusor at the compressor impeller outlet of a radial compressor has guide blades with stepped inlet edges. The step is implemented by setting back the hub-side inlet edge. This meridional stepping divides the guide blades into two component blades, of which the first component blade is made longer than the second component blade. The set-back of the inlet edge of the hub-side component blade and the associated superposition of the noise fields which are produced on the front and rear inlet edge of the diffusor leads to improvement of the acoustic properties of the compressor.

  • Publication number: 20110318164
    Abstract: The means of sealing the compressor wheel with respect to the bearing housing includes an annular sealing element which forms a sealing boundary face with a shaft edge and to which a spring force is applied in the direction of the shaft edge. The external spring force neither compensates or amplifies the pressure forces acting on the sealing element, irrespective of the direction of the difference in pressure. As a result, the sealing of the oil space in the bearing housing of the exhaust gas turbocharger with respect to the shaft is not influenced, or is influenced only to a small degree, by the pressure fluctuations in the wheel back space of the compressor.

  • Patent number: 8021106
    Abstract: A guide device with adjustable guide vanes is provided with a drive for the adjustable guide vanes, in which a cylindrical driving pin and an adjusting lever are provided each with one surface pair which are matched to one another and which slide on one another in operation when the guide vanes are being adjusted. To adjust the guide vanes, the adjusting ring is moved, by which the driving pin attached to the adjusting ring slides in an elongated groove of the adjusting lever and applies a force to the adjusting lever. This approach yields an economical and durable structure which is easy to install. This results in surface support with the corresponding low compressive loads per unit area and consequently greatly reduced wear.
