Patent number: 7802428Abstract: A subassembly of a system including an exhaust gas turbocharger system coupled with an internal combustion engine exhaust system, includes first and second components secured to each other, wherein the components are heated to an operational temperature by engine exhaust gases during engine operation. The components are secured to each other by or with a “low-melt material” whose melting temperature is less than the operational temperature, such that the low-melt material melts or at least loses its securing and/or positioning functionality upon operation of the engine and turbocharger system, and thus no longer performs any fastening or positioning function for the components. In some embodiments, temporary fasteners made of or including the low-melt material are employed for temporarily securing and positioning the components.Type: GrantFiled: October 4, 2007Date of Patent: September 28, 2010Assignee: Honeywell International, Inc.Inventors: Jean-Luc Perrin, Arthur Jeanson, Marylene Ruffinoni

The components are secured to each other by or with a “low-melt material”, i.e., a material whose melting temperature is less than the operational temperature, such that the low-melt material melts or at least loses its securing and/or positioning functionality upon operation of the engine and turbocharger system, and thus no longer performs any fastening or positioning function for the components. In some embodiment, temporary fasteners made of or including the low-melt material are employed for temporarily securing and positioning the components.Type: ApplicationFiled: October 4, 2007Publication date: April 9, 2009Inventors: Jean-Luc Perrin, Arthur Jeanson, Marylene Ruffinoni

Patent number: 7458764Abstract: A variable nozzle device for a turbocharger comprises an annular arrangement of vanes disposed in a nozzle formed between an inner wall and an outer wall, the outer wall being constituted by an axially displaceable member, wherein the axially displaceable member is displaceable by an action exerted from the side of the inner wall.Type: GrantFiled: February 19, 2003Date of Patent: December 2, 2008Assignee: Honeywell International, Inc.Inventors: Alain Lombard, Marylene Ruffinoni, Olivier Espasa

Patent number: 7338254Abstract: A turbocharger having a sliding piston assembly comprising a tubular piston disposed in the bore of the turbine housing such that the piston is axially slidable relative to the turbine housing. The piston assembly further comprises a tubular carrier inserted axially into the bore of the turbine housing surrounding the piston and fixed against axial movement relative to the turbine housing, a radially outer surface of the carrier engaging an inner surface of the bore and a radially inner surface of the carrier being slidably engaged by a radially outer surface of the piston. The carrier defines an axial split extending a length of the carrier, and the carrier is resiliently flexible. Accordingly, the axial split allows the carrier to expand and contract in diameter.Type: GrantFiled: November 29, 2005Date of Patent: March 4, 2008Assignee: Honeywell International, Inc.Inventors: Alain R. Lombard, Marylene Ruffinoni, Laurent Vautier

Patent number: 7024855Abstract: A turbocharger having a variable geometry turbine inlet incorporates a piston movable to vary the area of the inlet nozzle into the turbine. Vanes extending from the heat shield for flow control in the nozzle are engaged by the piston in a first closed position. In a second open position, the piston is spaced from the vanes increasing the inlet nozzle area.Type: GrantFiled: November 30, 2000Date of Patent: April 11, 2006Assignee: Honeywell International, Inc.Inventors: Jean-Luc Hubert Perrin, Olivier Espasa, Marylene Ruffinoni, Alain Lombard, Philippe Joseph Muller

Publication number: 20040025504Abstract: The invention concerns a turbocharger with a variable geometry turbine comprising a mobile cylindrical piston (70) to modify the cross-section of the input nozzle to the turbine. Vanes (90) extending from a heat shield (92) for adjusting the flow of the nozzle are contacted by the piston in a first closed position. In a second open position, the piston is spaced apart from the vanes, thereby increasing the input nozzle cross-section.Type: ApplicationFiled: April 28, 2003Publication date: February 12, 2004Inventors: Jean-Luc Hubert Perrin, Olivier Espasa, Marylene Ruffinoni, Alain Lombard, Philippe Joseph Muller
