Patent number: 10240518Abstract: A variable-geometry turbocharger (1) with a vane lever (11) that provides a stop function at full open position of the guide vanes (8). The integrated vane-open stop controls the full open position of the VTG mechanism. A vane lever (11) preferably has an integrated protrusion (50) that functions as a vane-open stop that contacts an adjacent vane lever (11), an integrated bolt (56), or the upper vane ring (16) at the full open position to regulate maximum exhaust gas flow to the turbine wheel (5).Type: GrantFiled: March 12, 2014Date of Patent: March 26, 2019Assignee: BorgWarner Inc.Inventors: Vahidin Alajbegovic, Daniel J.

Patent number: 10190378Abstract: A drilling head can include an annular seal assembly releasably secured in an outer housing, the annular seal assembly including an annular seal and an actuator that pressurizes a lubricant for delivery to an interior of the annular seal. A method can include positioning an annular seal in a drilling head, the annular seal including an inner liner having openings formed through a sidewall of the inner liner, and flowing a lubricant into an opening while the inner liner sealingly engages a tubular. In another method, the annular seal can have a minimum inner diameter for sealing engagement with a tubular, and a lubricant passage extending through the annular seal and intersecting an interior of the annular seal at a location spaced apart from the minimum inner diameter. A lubricant is flowed through the lubricant passage to the interior of the annular seal.Type: GrantFiled: July 28, 2016Date of Patent: January 29, 2019Assignee: Weatherford Technology Holdings, LLCInventors: Vahidin Alajbegovic, Lev Ring

Patent number: 8702381Abstract: The flow path of exhaust gas to the turbine wheel (70) of a turbocharger is influenced by relative motion between two rings of vanes, at least one of which being provided on a vane ring. The outer ring of vanes contains a plurality of vanes (92, 122), the inner ring of vanes contains a plurality of vanes (93, 121), and the inner and outer vanes in registry forming a single generic vane shape. The aerodynamic effect of relative displacement of the outer ring of vanes to the inner ring of vanes produces a modulate-able control of exhaust flow to the turbine wheel.Type: GrantFiled: December 4, 2009Date of Patent: April 22, 2014Assignee: BorgWarner Inc.Inventors: Vahidin Alajbegovic, Gordon Jenks

Patent number: 8485533Abstract: A dynamic seal assembly for installation between first and second relatively rotating members, comprising a ring for fixed engagement with said first member and an annular seal extending radially from said ring and configured to slidably engage said second member, wherein said radial seal has a thickness, and a length that is from about 1 to about 15 times greater than said thickness. In various embodiments, the seal is formed of a rubber composition comprising a vulcanized fluorocarbon elastomer dispersed in a matrix of a thermoplastic polymeric material. In various embodiments, the matrix forms a continuous phase and the vulcanized elastomeric material is in the form of particles forming a non-continuous phase. The compositions may be made by combining a curative, an uncured fluorocarbon elastomer, and a thermoplastic material, and heating the mixture to effect vulcanization of the elastomeric material, while applying mechanical energy.Type: GrantFiled: December 13, 2006Date of Patent: July 16, 2013Assignee: Freudenberg-NOK General PartnershipInventors: Edward H.

Patent number: 7891670Abstract: A dynamic seal provides for the return of captured lubricant to the lubricant side regardless of the direction of rotation between the seal and the shaft. The seal uses bi-directional pumping elements to facilitate the hydrodynamic pumping of the captured lubricant in response to relative rotation. The seal includes a valve portion that can change a pumping rate of particular pumping elements such that more lubricant is pumped toward the lubricant side than the non-lubricant side.Type: GrantFiled: February 1, 2008Date of Patent: February 22, 2011Assignee: Freudenberg-NOK General PartnershipInventor: Vahidin Alajbegovic
