Patent number: 9057280Abstract: An assembly can include vanes and a base configured to seat the vanes at a radial distance about an axis where each vane includes a leading edge and a trailing edge, a pair of lateral surfaces that meet at the leading edge and at the trailing edge, an extension that extends from one of the lateral surfaces and that has a contact surface, and a stop surface to form a contact with a contact surface of another vane to define a minimum flow distance between the vane and the other vane. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.Type: GrantFiled: January 31, 2012Date of Patent: June 16, 2015Assignee: Honeywell International Inc.Inventors: Nicolas Morand, Olivier Espasa, Francis Abel, Lorrain Sausse, Julien Mailfert, Frederic Favray, Emmanuel Bouvier

Patent number: 9017017Abstract: A variable-vane assembly for a variable nozzle turbine comprises a nozzle ring supporting a plurality of vanes affixed to vane arms that are engaged in recesses in the inner edge of a unison ring. The unison ring is rotatable about the axis of the nozzle ring so as to pivot the vane arms, thereby pivoting the vanes in unison. A plurality of guide pins for the unison ring are inserted into apertures in the nozzle ring and are rigidly affixed therein such that the guide pins are non-rotatably secured to the nozzle ring with a guide portion of each guide pin projecting axially from the face of the nozzle ring. Each guide portion defines a shoulder radially overlapping the inner edge of the unison ring such that the unison ring is restrained by the guide pins against excessive movement in both radial and axial directions.Type: GrantFiled: April 10, 2009Date of Patent: April 28, 2015Assignee: Honeywell Internatonal Inc.Inventors: Lorrain Sausse, Pierre Barthelet, Francis Abel, Olivier Espasa, Mohamed Tahyry, Emmanuel Bouvier

Patent number: 7762067Abstract: A turbocharger having a turbine housing defining a chamber for receiving exhaust gas, and a nozzle leading from the chamber. Exhaust gas flows from the nozzle through a turbine wheel in the chamber and changes direction from a radially inward direction in the nozzle to an axial direction downstream of the turbine wheel. A divider in the nozzle divides the nozzle into first-stage and second-stage nozzles. The divider has an upstream surface to guide exhaust gas through the first-stage nozzle and an opposite downstream surface to guide exhaust gas flowing through the second-stage nozzle. An axially slidable tubular piston, disposed in the turbine housing, has a radially inner surface extending along the axial direction and a non-flat upstream end surface. The piston also includes a curved flow-guiding surface causing the exhaust gas to change direction. In a closed position, the piston abuts the divider to close the second-stage nozzle.Type: GrantFiled: August 21, 2007Date of Patent: July 27, 2010Assignee: Honeywell International, Inc.Inventors: Emmanuel Bouvier, Lorrain Sausse, Quentin Roberts, Pierre Barthelet

Publication number: 20100021287Abstract: A turbocharger includes a thin-walled insert installed in the bore of the turbine housing. The insert is generally ring-shaped and is radially resilient. The insert can be made of sheet metal formed into a ring shape, and in some embodiments is a split ring. A piston is axially slidable in the bore for varying the size of the turbine nozzle. The outer surface of the piston slides against the inner surface of the insert, and in preferred embodiments a piston ring that encircles the piston engages the inner surface of the insert to substantially seal the interface between the insert and the piston.Type: ApplicationFiled: July 24, 2008Publication date: January 28, 2010Inventors: Emmanuel Bouvier, Lorrain Sausse, Pierre Barthelet, Manuel Marques, Laurent Vautier, Francis Abel, Alain Claudon
