Publication number: 20140001005Abstract: A failsafe system for a heavy-duty multi-speed clutch includes a thermal valve coupled within a clutch pressure tube orifice circuit protecting a clutch pack from heat degradation. When oil temperature of the clutch reaches a level where thermal degradation can occur, the thermal valve allows flow into a clutch piston system at a maximum operating pressure, thereby engaging a clutch drive and cooling the clutch to a safe condition.Type: ApplicationFiled: September 2, 2013Publication date: January 2, 2014Applicant: BORGWARNER INC.Inventors: Dale M.

Patent number: 7047911Abstract: A hydraulically controlled fan drive system for controlling the cooling of an engine and having a method of engagement includes a housing assembly containing a hydraulic fluid and an engaging circuit. The engaging circuit includes a pitot tube coupled within the housing assembly that receives at least a portion of the hydraulic fluid as the housing assembly rotates to drive a clutch pack (and coupled fan) via static pressure. A fluid controller having binary control adjusts the static pressure within the pitot tube at a given rotational speed, thereby controlling the engagement of the clutch pack to a fully engaged drive (utilizing friction type engagement), a fully disengaged drive, and at least two partially engaged clutch positions (i.e. partially engaged utilizing a wet viscous type clutch engagement). To control static pressure release, the fluid controller may utilize a dual spool system valving arrangement or a parallel fixed orifice binary control.Type: GrantFiled: August 27, 2003Date of Patent: May 23, 2006Assignee: BorgWarner Inc.Inventors: Neil E.

Patent number: RE39891Abstract: A novel impeller for a regenerative turbine fuel pump improves the efficiency of the pump and yet still retains a geometry that allows it to be manufactured by conventional injection molding techniques at a relatively low cost. The impeller comprises a hub, an outer ring and a plurality of innovative V-shaped vanes. The hub defines an aperture into which the shaft of the pump is securable to allow the hub to rotate about a center axis. The outer ring is concentric to the hub. The vanes extend from an outer surface of the hub to an inner surface of the outer ring. Each vane comprises an entrance portion that extends from the outer surface of the hub and an exit portion that extends from the entrance portion to the inner surface of the outer ring. Each vane has a V-shape of a prespecified angle centered relative to a plane normal to the center axis.Type: GrantFiled: April 8, 2004Date of Patent: October 23, 2007Assignee: Delphi Technologies, Inc.Inventors: Dale M.
