摘要： A turbine includes a turbine housing (215) including at least two gas passages (236) having substantially the same flow area and disposed on either side of at least one divider wall (240). A turbine wheel (212) includes a plurality of blades (214). A nozzle ring (238) is connected to the turbine housing (215) and disposed around the turbine wheel. The nozzle ring (238) includes an inner ring (242) disposed adjacent the divider wall (240) and at least one outer ring (238). A plurality of vanes (246) is fixedly disposed between the inner and outer rings. The vanes define a plurality of inlet openings (258) therebetween that are in fluid communication with a slot (230) formed in the ring and surrounding the turbine wheel (212). The inner ring (242) is disposed to block a portion of the inlet openings (258) that fluidly communicate with one of the at least two gas passages (236) in the turbine housing (215).

摘要： A journal bearing for use with a turbocharger includes a free floating bushing rotatable between a shaft and housing. In one embodiment, a single oil feed passage is provided at an angle in the housing, and a number of radially disposed oil transfer passages are provided in the free floating bushing. The angle of the housing passage relative the bushing passages is such that oil flowing between the passages imparts an angular momentum to the bushing opposite the shaft rotation to slow the rotational velocity of the bushing. Alternately, the housing passage may be radially disposed and the bushing passages may be inclined at an angle relative to the housing passage to similarly impart an angular momentum to the floating bushing in a direction opposite the directing of rotation of the shaft, or both the housing passage and the bushing passages may be inclined relative one another to impart an angular momentum to the bushing in a direction opposite the direction of rotation of the shaft.

摘要翻译： 用于涡轮增压器的轴颈轴承包括可在轴和壳体之间旋转的自由浮动衬套。 在一个实施例中，在壳体中以一定角度设置单个进油通道，并且在自由浮动衬套中设置多个径向设置的输油通道。 壳体通道相对于衬套通道的角度使得在通道之间流动的油将轴向旋转的轴向动量向衬套施加以减小衬套旋转速度。 或者，壳体通道可以径向设置并且衬套通道可以相对于壳体通道以一定角度倾斜，以类似地在垂直于轴的转动方向相反的方向上向浮动衬套施加角动量，或者两个壳体 通道和衬套通道可以相对倾斜，以在与轴的旋转方向相反的方向上向衬套施加角动量。

摘要： A turbocharger for a power system is disclosed. The turbocharger has an impeller wheel, which is rotatable about a central axis and includes a back face at least partially defining a reference plane substantially perpendicular to the central axis. In addition, the turbocharger includes a housing configured to at least partially enclose the impeller wheel. The housing also has at least one volute configured to fluidly communicate fluid with the impeller wheel. The entire length of the at least one volute from a turbocharger inlet is axially inclined relative to the reference plane so the fluid flows in both a radial and axial direction.

摘要： A compound turbocharger is provided, including at least one housing. A first turbocharger having an outer shaft is disposed within the housing, and a second turbocharger is provided having an inner shaft co-axial with and extending within the outer shaft. At least one displacement limiter is disposed at a selected position along the length of the outer shaft. A method of reducing vibrational amplitude in an inner shaft of a coaxial shaft assembly is further provided, including the step of operably positioning at least one displacement limiter at a selected position along a length of the outer shaft.
