Abstract: A turbocharger for a power system is disclosed. The turbocharger has a turbine wheel and a housing configured to at least partially enclose the turbine wheel. The housing has a first turbine volute configured to fluidly communicate exhaust gases with the turbine wheel, a second turbine volute configured to fluidly communicate exhaust gases with the turbine wheel, a wall member axially separating the first and second turbine volutes. The housing also has a first plurality of annularly disposed vane members associated with at least one of the first and second turbine volutes.

Abstract: 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.

Abstract: An electrical contact comprises a compliant section (1) with a plurality of spring members (2), a U-shaped retention section (5) with a pair of arms (6) having sharp barbs (7), and a tubular section (8) with a pair of flexible beams (9) and a C-shaped rigid beam (10) with a stop tab (11).
