Publication number: 20190330995Abstract: A turbocharger having a divided turbine housing scroll includes separate first and second exhaust gas conduits for feeding separate streams of exhaust gas to two separate scrolls in the turbine housing. A cross-scroll communication control valve in the turbine housing is operable to selectively allow or prevent two separate streams of exhaust gas in the turbine housing to fluidly communicate with each other. The valve member rotates about a valve axis that is parallel to a flow axis along with the exhaust gas flows in the exhaust gas conduits. The valve member tapers in the flow direction. In a first position, the valve member has walls that close off a cross-communication opening between the two exhaust gas conduits, thereby isolating the conduits from each other. In a second position, a through-passage of the valve member becomes aligned with the cross-communication opening to allow cross-talk between the two conduits.Type: ApplicationFiled: April 25, 2018Publication date: October 31, 2019Applicant: Honeywell International Inc.Inventors: Nathaniel Bontemps, Michael Ladonnet, Alain Lombard, Philippe Arnold, Alain Bas, Nandor Pallag, Denis Jeckel, Ludek Pohorelsky

Patent number: 10227889Abstract: An assembly can include an exhaust gas turbine housing that includes an inner wall and an outer wall that define a first exhaust gas channel and a second exhaust gas channel to a turbine wheel space where the inner wall includes an inner wall end at the turbine wheel space and the outer wall includes an outer wall end at the turbine wheel space; a first adjustable divider vane disposed adjacent to the inner wall end; a second adjustable divider vane disposed adjacent to the outer wall end; and at least one set of adjustable variable geometry nozzle vanes that define nozzle throats that direct flow of exhaust gas from one of the exhaust gas channels to the turbine wheel space.Type: GrantFiled: January 11, 2016Date of Patent: March 12, 2019Assignee: Garrett Transportation I Inc.Inventors: Philippe Arnold, Denis Jeckel, Christophe Riviere, Dominique Petitjean, Peter Rhys Davies, Nathaniel Bontemps

Patent number: 9765687Abstract: A turbocharger includes a variable turbine nozzle formed between first and second walls. A variable-vane assembly has a fixed nozzle ring and a plurality of circumferentially spaced vanes disposed in the nozzle and rotatably mounted on the nozzle ring such that the vanes are pivotable. The nozzle ring defines the first wall of the turbine nozzle, each vane having a first end adjacent the first wall and a second end adjacent the second wall. The second wall of the turbine nozzle is formed by a gas pressure-responsive member that is arranged to be axially movable relative to the vanes. A first stop is positioned so that the gas pressure-responsive member is urged against the first stop by a differential gas pressure exerted on the gas pressure-responsive member so that there is a non-zero first value for a clearance between the second ends of the vanes and the second wall of the turbine nozzle.Type: GrantFiled: April 29, 2014Date of Patent: September 19, 2017Assignee: Honeywell International Inc.Inventors: Philippe Arnold, Denis Jeckel, Peter Rhys Davies, Christophe Riviere, Gregory Do, Dominique Petitjean, Shankar Pandurangasa Solanki

Patent number: 8967955Abstract: A variable nozzle for a turbocharger includes a plurality of vanes rotatably mounted on a nozzle ring and disposed in a nozzle flow path defined between the nozzle ring and an opposite nozzle wall. Either or both of the faces of the nozzle ring and nozzle wall include(s) grooves extending substantially transverse to a general flow direction of the flow through the nozzle, and there are clearances between the ends of the vanes and the adjacent faces. Leakage flow through the clearance between the end of each vane and the adjacent face having the grooves must proceed across the grooves, and thus a labyrinthine flow passage is presented to the leakage flow. The labyrinthine passage has a greater resistance to flow than would be the case without the grooves. Accordingly, leakage flow is reduced, which is beneficial to turbine efficiency.Type: GrantFiled: September 26, 2011Date of Patent: March 3, 2015Assignee: Honeywell International Inc.Inventors: Pierre Barthelet, Emmanuel Severin, Nicolas Morand, Denis Jeckel, Dominique Petitjean, Philippe Arnold, Karl-Heinz Bauer

Patent number: 8967956Abstract: A variable-nozzle assembly for a turbocharger includes a generally annular nozzle ring and an array of vanes rotatably mounted to the nozzle ring such that the vanes can be pivoted about their axes for regulating exhaust gas flow to the turbine wheel. A unison ring engages vane arms that are affixed to axles of the vanes, such that rotation of the unison ring causes the vanes to pivot between a closed position and an open position. The vanes have proximal ends that are adjacent a face of the nozzle ring. A vane sealing member is supported on the nozzle ring and has a portion disposed between the proximal ends of the vanes and the face of the nozzle ring. The unison ring includes cams that engage cam followers. Rotational movement of the unison ring causes the cam followers to be moved axially and thereby urge the vane sealing member against the proximal ends of the vanes.Type: GrantFiled: September 26, 2011Date of Patent: March 3, 2015Assignee: Honeywell International Inc.Inventors: Philippe Arnold, Denis Jeckel, Dominique Petitjean, Pierre Barthelet, Emmanuel Severin, Nicolas Morand, Karl-Heinz Bauer, Chris Groves

Patent number: 8056336Abstract: A variable nozzle for a turbocharger includes a plurality of vanes rotatably mounted on a nozzle ring and disposed in a nozzle flow path defined between the nozzle ring and an opposite nozzle wall. Either or both of the faces of the nozzle ring and nozzle wall include(s) at least one step that defines sealing surfaces positioned to be substantially abutted by airfoil surfaces of the vanes in the closed position of the vanes and to be spaced from the airfoil surfaces in positions other than the closed position. This substantial abutment between the airfoil surfaces and the sealing surfaces serves to substantially prevent exhaust gas from leaking past the ends of the airfoil portions. At the same time, clearances between the nozzle ring face and the end faces of the airfoil portions can be sufficiently large to prevent binding of the vanes under all operating conditions.Type: GrantFiled: May 5, 2008Date of Patent: November 15, 2011Assignee: Honeywell International Inc.Inventors: Philippe Arnold, Dominique Petitjean, Anthony Ruquart, Guillaume Dupont, Denis Jeckel
