Patent number: 9222378Abstract: A cam phaser includes a rotor, a stator, and a cover. The rotor defines a first hole and a second hole and can rotate relative to the stator between a first intermediate position and a second intermediate position. The cover is mounted on the stator and defines a first lock pin seat and a second lock pin seat. The cam phaser includes a first lock pin and a second lock pin. The first lock pin can move along the first hole and into the first lock pin seat to lock the rotor relative to the stator at the first intermediate position.

Patent number: 8770162Abstract: A lifter guide includes a lifter guide body having an outer surface and an inner surface that extend from a first end to a second end. The inner surface defines at least one push rod passage. A plurality of compression members are provided at the first end. The plurality of compression members project proudly from the first end. The plurality of compression members are configured and disposed to be compressed by a cylinder head to retain the lifter guide in a cylinder block. The lifter guide is devoid of mechanical fasteners.Type: GrantFiled: November 27, 2012Date of Patent: July 8, 2014Assignee: GM Global Technology Operations LLCInventors: Nick John Hendriksma, Gerald R.

Patent number: 8677962Abstract: A motion limiter system for a cam phaser includes a retractable motion limiter pin that is selectively extendable from a rotor in a cam phaser to contact a lobe on a stator to provide a positive stop for the rotor prior to engagement of a locking pin. Alternatively, the cam phaser may include two pins that are selectively extendable from opposite openings in a hole in the rotor to engage seats that are slightly offset from one another.Type: GrantFiled: May 3, 2012Date of Patent: March 25, 2014Assignee: GM Global Technology Operations LLCInventors: William P. Vukovich, Gerald R. Stabel, Brian R. Webb

Patent number: 8070922Abstract: An oxygen generator includes a monolithic body having first and second channels extending longitudinally therein. An electrode is operatively disposed in the first channels and a counter-electrode is operatively disposed in the second channels. The second channels are formed in the monolithic body so each second channel is electrically isolated from, yet adjacent to a first channel, resulting in an alternating configuration of first and second channels. The first channels have fluid or oxygen flowing therethrough, while the second channels have the other of oxygen or fluid flowing therethrough. An output manifold, having an oxygen collection area separated from a fluid collection area, operatively engages with the monolithic body. The oxygen collection area receives substantially pure oxygen from one of the second or first channels, and the fluid collection area receives oxygen-depleted fluid from the other of the first or second channels.Type: GrantFiled: August 7, 2006Date of Patent: December 6, 2011Assignee: Oxus America, Inc.Inventors: David E. Nelson, Gerald R. Stabel, Joshua J. Titus, Alfred R. Webster

Publication number: 20090126527Abstract: A bearing design for a roller finger follower assembly includes an outer arm having a pair of openings, a shaft extending across the outer arm through the openings, a pair of lateral follower rollers mounted at opposite ends of the shaft; and a pair of bearings rotatably supporting the lateral follower rollers. The shaft is not a member of the bearing. Therefore, a force acting on the rollers travels through the rollers directly into the bearing and into the outer arm which reduces the potential for the rollers to become detached from the shaft. An inboard bearing design involves an inner bearing race integrated into the rollers. An outboard bearing design involves an inner bearing race integrated in the outer arm and an outer bearing race integrated into the rollers.Type: ApplicationFiled: November 21, 2007Publication date: May 21, 2009Inventors: William D. Bauman, Michael J. Okenka, Gerald R. Stabel, Albert C. Stone, Ryan D. Fogarty

Patent number: 6851175Abstract: A method of inserting coils in slots of a stator is provided. The method includes interleaving a first set of first phase windings and a first set of second phase windings on an insertion tool. The method also includes activating the insertion tool to radially insert the first set of first phase windings and the first set of second phase windings in the slots of the stator. In one embodiment, interleaving the first set of first phase windings and the first set of second phase windings on the insertion tool includes forming the first set of first phase windings in first phase openings defined in the insertion tool, and forming the first set of second phase windings in second phase openings defined in the insertion tool.Type: GrantFiled: September 12, 2001Date of Patent: February 8, 2005Assignee: Delphi Technologies, Inc.Inventors: David L Brown, Gerald R Stabel, Robert Anthony Lawrence

Patent number: 6578255Abstract: A segmented core for an electric machine includes segments stamped from coated electric steel. The segments each have a first end, a second end, and winding openings. A predetermined number of segments are placed end-to-end to form layers. The layers are stacked such that each of the layers is staggered from adjacent layers by a predetermined rotation angle. The winding openings of each of the layers are in vertical alignment with the winding openings of the adjacent layers. The stack of layers is secured to form the segmented core.Type: GrantFiled: May 14, 2001Date of Patent: June 17, 2003Assignee: Delphi Technologies, Inc.Inventors: Robert Anthony Lawrence, Gerald R Stabel
