Patent number: 9995161Abstract: A turbocharger shaft is sealed with respect to the bore of the bearing housing at the turbine wheel end by one or more shaft seal rings. Conventionally these rings are seated in annular grooves provided in the shaft behind the turbine wheel. Problems can arise with this conventional shaft seal arrangement, particularly where the turbocharged engine has an engine brake valve located downstream of the turbine, and the back pressure in the exhaust line, and thus in the turbine wheel housing, can reach 7 bar. The inventive shaft seal design avoids grooves, and makes it possible to assemble a seal with ring seals with higher wear resistance and thus to maintain the seal's effectiveness over heavy use.Type: GrantFiled: November 10, 2015Date of Patent: June 12, 2018Assignee: BorgWarner Inc.Inventor: Allan Kelly

Publication number: 20150330240Abstract: The propensity for oil leakage around the clearance seals of a rotating turbocharger assembly can be minimized by the addition of a variety of sealing systems using an externally pressurized cavity formed between the backface of the compressor wheel and the bearing housing. In one implementation, a pressure plate can be provided. In another embodiment, labyrinth seals can be provided. In addition to these various sealing arrangements, external pressurized air or internally supplied charge air can be selectively supplied to the space behind the pressure plate or labyrinth seal to maintain an inward directed pressure gradient across the seal interface regardless of operating conditions.Type: ApplicationFiled: November 26, 2013Publication date: November 19, 2015Inventors: Allan KELLY, E.

Patent number: 9068598Abstract: To solve both axial and rotational constraint problems in turbochargers with rolling element bearings (REBs), a REB cartridge is mounted to the bearing housing in a way that is not rigid, thus allowing for an oil damping film. At the same time, the REB cartridge is held both axially and rotationally, so that the outer race does not rotate relative to the bearing housing. This dual purpose is achieved using a special dual-mode sliding clip with at least one anti-rotation feature for engaging the bearing housing and at least one anti-rotation feature for engaging the REB cartridge, thereby axially locating the REB cartridge and preventing rotation of the outer race.Type: GrantFiled: April 30, 2010Date of Patent: June 30, 2015Assignee: BorgWarner Inc.Inventors: Timothy House, Paul Diemer, Allan Kelly, Augustine Cavagnaro

Patent number: 8814538Abstract: A turbocharger using a high speed rolling element bearing system is improved in desired speed and life by providing an insulating spacer, with a thermal conductivity lower than that of the material in the inner race of the REB, between the turbine-end of the inner race of the bearing system and the compressor-end face of the piston ring boss to impede the flow of heat from the turbine wheel to the inner race of the rolling element bearing.Type: GrantFiled: April 16, 2010Date of Patent: August 26, 2014Assignee: BorgWarner Inc.Inventors: Timothy House, Paul Diemer, Allan Kelly, Augustine Cavagnaro

Patent number: 8807840Abstract: A turbocharger uses a high speed rolling element bearing system. An exemplary rolling element bearing system includes a polymer sleeve to impede the flow of heat from the bearing housing into the outer race of the rolling element bearing system.

Patent number: 8197183Abstract: A turbocharger thrust bearing assembly, which maintains a constant relationship between the thrust faces, for example by use of gimbal or spherical segment geometry. Spherical geometry, while more difficult to manufacture than that of a flat thrust bearing, provides a more constant relationship between the thrust pads and thrust washers than is possible with a typical flat thrust bearing. As a consequence of this more constant relationship the thrust bearing operates with less oil flow, which ultimately may reduce vehicle emissions.Type: GrantFiled: July 1, 2009Date of Patent: June 12, 2012Assignee: BorgWarner Inc.Inventors: Daniel Ward, Allan Kelly

Publication number: 20110146042Abstract: A method of manufacture of a polymer or ceramic polymer capacitor, of various sizes and voltage ratings. The fabrication equipment deposits a polymer or ceramic polymer dielectric layer on a carrier substrate with the electrode structure of the capacitor previously deposited on its surface. The sheet is often then fabricated into a capacitor by rolling into an axial style or the sheet is cut and stacked into a rectangular type. An alternate arrangement of the fabrication process has additional electrode layers deposited alternating with dielectric layers in continuous process until the desired number of layers is achieved. At that point the sheet is cut to form capacitors of a rectangular form.Type: ApplicationFiled: September 11, 2009Publication date: June 23, 2011Inventors: David Allan Kelly, Donna Lee Kelly
