Patent number: 8556194Abstract: A fuel injector that includes a flying armature movable relative to a pintle stop, and an electromagnetic circuit configured to move the flying armature away from the pintle stop prior to accelerating the armature toward the pintle stop as part of moving the pintle to open the fuel injector. The flying armature increases the total force applied to the pintle to open the fuel injector by supplementing the static force imparted to the armature by a magnetic field with an impact force imparted by the armature being in motion toward and impacting with the pintle stop. The arrangement of magnetic circuit devices and materials used to make the magnetic circuit devices cooperate to provide a reversing force that urges the armature away from before urging the armature toward the pintle stop, and increases the rate at which the force that urges the armature toward the pintle stop increases.Type: GrantFiled: June 23, 2010Date of Patent: October 15, 2013Assignee: Delphi Technologies, Inc.Inventors: Harry R. Mieney, Michael Raymond Raney, Michael Raymond Salemi, Robert B. Perry

Patent number: 7048516Abstract: A fuel pump for supplying fuel at high fuel pressures includes a stationary body having a plurality of radial cylinders connecting with a central fuel chamber. Inlet and outlet passages communicate with the fuel chamber. Plungers are reciprocated in the cylinders by cam followers reciprocable in follower recesses of the body. A rotary internal cam engages the cam followers and is configured to reciprocate the plungers in timed relation to sequentially draw fuel from the inlet passage into the central fuel chamber and alternately force fuel from the central fuel chamber to the outlet passage in response to rotation of the rotary cam. A preferred embodiment includes paired smaller and larger diameter cylinders and pistons which are sequentially actuated in overlapping fashion to minimize pulsing of the pressurized fuel discharged from the pump into associated engine fuel lines.Type: GrantFiled: June 9, 2003Date of Patent: May 23, 2006Assignee: Delphi Technologies, Inc.Inventors: Eugen Maier, Michael Raymond Raney

Patent number: 6769889Abstract: A gerotor pump for pressurizing gasoline fuel is capable of developing pressures up to 2.0 MPa with good mechanical and volumetric efficiency and satisfying the durability requirements for an automotive fuel pump. The pump has been designed with optimized clearances and by including features that promote the formation of lubricating films of pressurized fuel. Features of the improved pump include the use of a shadow port in the side plate opposite the outlet port to promote balancing of high fuel pressures on the opposite sides of the rotors. Inner and outer rotors have predetermined side clearances with the clearances of the outer rotor being greater than those of the inner rotor in order to promote fuel pressure balance on the sides of the outer rotor. Support of the inner rotor and a drive shaft on a single bushing with bearing sleeves maintains concentricity. Additional features are disclosed.Type: GrantFiled: April 2, 2003Date of Patent: August 3, 2004Assignee: Delphi Technologies, Inc.Inventors: Michael Raymond Raney, Eugen Maier

Patent number: 6758656Abstract: A multi-stage internal gear/turbine fuel pump for a vehicle includes a housing having an inlet and an outlet and a motor disposed in the housing. The multi-stage internal gear/turbine fuel pump also includes a shaft extending axially and disposed in the housing. The multi-stage internal gear/turbine fuel pump further includes a plurality of pumping modules disposed axially along the shaft. One of the pumping modules is a turbine pumping module and another of the pumping modules is a gerotor pumping module for rotation by the motor to pump fuel from the inlet to the outlet.Type: GrantFiled: April 19, 2002Date of Patent: July 6, 2004Assignee: Delphi Technologies, Inc.Inventors: Eugen Maier, Michael Raymond Raney

Patent number: 6629650Abstract: An engine fuel injector includes an internal fuel passage in which pressure waves can develop upon opening and closing of an injection valve. A fuel pressure damper is associated with the fuel passage and operates to vary the internal volume of the fuel passage in a manner to reduce the amplitude of pressure variations and pressure waves in the fuel passage. A variety of fuel pressure damper embodiments are disclosed.Type: GrantFiled: July 10, 2001Date of Patent: October 7, 2003Assignee: Delphi Technologies, Inc.Inventors: Steven M. Curran, Ahmet T. Becene, Charles Wilson Braun, Kern E. Haynes, Leonard Lee Shebert, Jr., Christopher A. Tucker, David J. Thompson, Jr., Brent Jack Wahba, Michael Raymond Raney, James M. Banna
