Patent number: 11566537Abstract: A water-cooled compressor housing assembly for a turbocharger includes a compressor housing that defines an open-ended cavity extending axially downstream into the compressor housing, and a separately formed cover that is affixed to the compressor housing so as to close the open end of the cavity and thereby define a coolant passage for a liquid coolant to be circulated through. A coolant inlet and a coolant outlet are provided for supplying coolant into and exhausting coolant from the coolant passage. The compressor housing has a simplified geometry that is manufacturable by sand casting without needed a sand core for the coolant passage, or by die casting.Type: GrantFiled: October 12, 2020Date of Patent: January 31, 2023Assignee: Garrett Transportation I Inc.Inventors: Manuel Marques, Olivier Millotte, Emeric Genin, Jean-Pierre Toniolo

Patent number: 10465698Abstract: A turbocharger assembly includes a compressor wheel with a base surface, a nose surface, a z-plane disposed between the base surface and the nose surface and a bore extending from the base surface to the nose surface and a shaft that includes a first pilot surface disposed in the bore of the compressor wheel at a position between the z-plane and the nose surface, a second pilot surface disposed in the bore of the compressor wheel at a position between the z-plane and the base surface, and a recessed surface disposed between the first pilot surface and the second pilot surface. A nut adjustably disposed on the shaft adjacent to the nose surface can tension the shaft to apply a compressive load between the base surface and the nose surface of the compressor wheel. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.Type: GrantFiled: November 8, 2011Date of Patent: November 5, 2019Assignee: Garrett Transportation I Inc.Inventors: Joel Castan, Dominique Armand, Gerard Dieudonne, Olivier Millotte, Lionel Toussaint

Patent number: 9051848Abstract: A turbocharger assembly includes: a housing with a through-bore and a cross-bore that intersects the through-bore to define an upper portion of the cross-bore with a first diameter and a lower portion of the cross-bore with a second diameter where the first diameter exceeds the second diameter; a bearing disposed in the through-bore of the housing where the bearing includes a through-bore configured to support a shaft and a cross-bore that intersects the through-bore; and a locating pin with a diameter that exceeds the second diameter of the lower portion of the cross-bore of the housing, the locating pin press-fit at least partially into the lower portion of the cross-bore of the housing and disposed at least partially in the lower portion of the cross-bore of the bearing to locate the bearing in the through-bore of the housing. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.Type: GrantFiled: November 8, 2011Date of Patent: June 9, 2015Assignee: Honeywell International Inc.Inventors: Joel Castan, Dominique Armand, Gerard Dieudonne, Lionel Toussaint, Olivier Millotte

Patent number: 8763393Abstract: A turbocharger includes a variable-nozzle assembly that includes an insert having a tubular portion received into a stepped bore of a turbine housing and having a nozzle portion extending radially out from one end of the tubular portion, and a generally annular nozzle ring axially spaced from the nozzle portion and an array of vanes rotatably mounted to the nozzle ring. Sealing of the interface between the tubular portion of the insert and the turbine housing is provided by a sealing ring formed as a generally annular body having a U- or V-shaped cross-section oriented such that an open side of the U- or V-shaped cross-section faces in a radial direction. The U- or V-shaped cross-section defines two opposing legs, one of the legs being engaged against an end face of the tubular portion of the insert and the other leg being engaged against an upstream-facing step surface of the turbine housing bore.Type: GrantFiled: August 8, 2011Date of Patent: July 1, 2014Assignee: Honeywell International Inc.Inventors: Emmanuel Severin, Pierre Barthelet, Lionel Toussaint, Olivier Millotte
