20090272112 | TURBOCHARGER WITH VARIABLE NOZZLE HAVING VANE SEALING SURFACES - 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. | 11-05-2009 |
20110176907 | MULTI-PIECE TURBOCHARGER BEARING - An exemplary multi-piece bearing for a turbocharger includes a cylindrical piece that has a coefficient of thermal expansion, opposing ends and an outer surface and an inner surface that extend between the opposing ends where the outer surface includes one or more lubricant openings; an end piece that has a different coefficient of thermal expansion and a face where the face includes one or more lubricant openings; and lubricant passages formed by the cylindrical piece and the end piece for passage of lubricant between the one or more lubricant openings of the outer surface of the cylindrical piece and the one or more lubricant openings of the face of the end piece. As described herein, such an exemplary multi-piece bearing can, upon selection of coefficients of thermal expansion, help maintain axial clearances between various components during operation of a turbocharger. Other exemplary bearings, arrangements and methods are also disclosed. | 07-21-2011 |
20120014782 | TURBOCHARGER BEARING HOUSING ASSEMBLY - An assembly for a turbocharger that includes a bearing housing with a cylindrical portion with a bore configured for receipt of a bearing, an extension that extends radially outwardly from the cylindrical portion to a base, the base configured with one or more features for securing the bearing housing to another component, a compressor fitting, a turbine fitting, and lubricant flow paths; and a fluid jacket that includes a cylindrical wall configured for placement over at least a portion of the cylindrical portion of the bearing housing where the cylindrical wall includes a recess configured to accommodate at least a portion of the extension of the bearing housing, a fluid inlet, and a fluid outlet. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed. | 01-19-2012 |
20130078082 | TURBOCHARGER VARIABLE-NOZZLE ASSEMBLY WITH VANE SEALING ARRANGEMENT - 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. | 03-28-2013 |
20130078083 | TURBOCHARGER WITH VARIABLE NOZZLE HAVING LABYRINTH SEAL FOR VANES - 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. | 03-28-2013 |
20150308330 | TURBOCHARGER WITH VARIABLE-VANE TURBINE NOZZLE HAVING A GAS PRESSURE-RESPONSIVE VANE CLEARANCE CONTROL MEMBER - 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. | 10-29-2015 |
