Patent number: 7509903Abstract: A separable structure includes composite material that is separated or severed by a reactive pyrotechnic material. According to one embodiment, the structure includes a pair of composite laminate structural portions, each including multiple layers of composite material. The portions each extend into an overlap region, within which the composite layers of the two structural portions may be alternately placed, overlapping one another. A reactive material is also placed within this overlap region, for instance being in layers between pairs of the composite material layers. The reactive material may be ignited to cause destruction of the pyrotechnic material, and a matrix or resin material of the composite materials layers in the overlap region. This causes the structure to sever or separate along a line of separation within the overlap region. The separation may occur without need to sever fibers of the composite material.Type: GrantFiled: July 27, 2005Date of Patent: March 31, 2009Assignee: Raytheon CompanyInventors: Andrew B.

A solenoid valve within the assembly diverts hydraulic fluid between support and non-support of a piston slidably disposed in a housing and terminating in a ball head. The valve is force-balanced. The preferred hydraulic fluid is diesel fuel, allowing for smaller diameter passages and cleaner operation than in prior art systems, eliminating the need for an accumulator chamber and accumulator piston as in the prior art. An alternate version of a type 3 engine having a DHLA, in accordance with the invention, is also shown.Type: GrantFiled: March 6, 2006Date of Patent: March 31, 2009Assignee: Delphi Technologies, Inc.Inventor: Philip J.

Patent number: 7509939Abstract: A throttle control apparatus comprises a throttle valve placed in an intake passage, a motor for driving the throttle valve, an electronic control unit (ECU) for controlling the motor, and a throttle sensor for detecting an actual opening degree of the throttle valve. The ECU determines that the throttle valve is frozen when the actual opening degree does not reach a target opening degree even after a driving time for driving the motor has exceeded a predetermined time, and then stores the actual opening degree at the time as an icing opening degree. The ECU supplies a driving duty to cause the motor to produce required driving torque for removal of icing and reverses the driving duty by open control, and controls the motor to bring an accumulated value of a deviation between the target opening degree and the icing opening degree to zero, thereby repeatedly swinging the throttle valve.Type: GrantFiled: February 13, 2007Date of Patent: March 31, 2009Assignees: Aisan Kogyo Kabushiki Kaisha, Toyota Jidosha Kabushiki Kaisha, Denso CorporationInventors: Hideki Asano, Katsumi Ishida, Tsutomu Miyazaki, Kazuhiro Minamitani, Shigeru Kamio, Akihiro Kamiya

Patent number: 7509941Abstract: An apparatus and method for use with a carbureted internal combustion engine that accurately controls the amount of fuel that passes through the carburetor into the combustion chamber of the engine. A controlled triggering system controls the activation and deactivation of a solenoid. The solenoid, in turn, operates a plunger that varies the flow of fuel during the fuel intake cycle of the engine depending on the amount of fuel needed by the engine under any operating load. Thus, an engine can run leaner under partial load and run richer during periods of load and acceleration. By controlling the air-to-fuel ratio lower engine emissions and fuel consumption can be achieved.Type: GrantFiled: March 6, 2007Date of Patent: March 31, 2009Assignee: Phelon Euro ABInventors: Lars Ottosson, Jorgen Bengtsson, Bert Gustafsson

Patent number: 7509944Abstract: In an engine fuel supply method, a first fuel pressure difference between a fuel injection amount computation timing and a first fuel injection timing and a second fuel pressure difference between the fuel injection amount computation timing and a second fuel injection timing are estimated at the fuel injection amount computation timing based on a control state of a fuel pneumatic transportation amount of a high-pressure fuel pump. The first fuel injection amount is corrected based on the first fuel pressure difference and the second fuel injection amount is corrected based on the second fuel pressure difference. A fuel injection valve is selectively controlled to supply the high-pressure fuel directly into a cylinder of the engine at the first fuel injection timing with the corrected first fuel injection amount and at the second fuel injection timing with the corrected second fuel injection amount.Type: GrantFiled: June 4, 2007Date of Patent: March 31, 2009Assignee: Nissan Motor Co., Ltd.Inventor: Manabu Okamura

Patent number: 7509945Abstract: A fuel pump controller includes a detecting device for detecting environmental vibrational energy and converting the environmental vibrational energy into an electrical signal. A motor controller is coupled to a fuel pump motor wherein the electrical signal is used by the controller to command the fuel pump motor to operate at one of a plurality of speeds wherein the commanded speed is at least in part a function of the environmental vibrational energy.Type: GrantFiled: March 15, 2007Date of Patent: March 31, 2009Assignee: Chrysler LLCInventors: Michael R. Teets, Trevor L. Enge, Lavern M. Bremmer, Jon R. Donegan, Greg Schoenberg

Patent number: 7509946Abstract: A method for controlling a piezoelectric actuator of a fuel injector for controlling the quantity of fuel injected into the cylinders of an internal combustion engine controls the voltage across the injector in accordance with a voltage/charge vs. time profile in which the injector is driven at high current up to a level required to start injection, and then at lower current, resulting in a lower voltage/charge vs. time gradient, until the point where full charge is achieved. This results in a reduced variation in minimum delivery pulse and a reduction in the slope of the gain curve, as compared with conventional arrangements in which the voltage/charge vs. time gradient is constant. Alternatively, the injector may be driven at high current up to the charge level required to switch to hydraulic lift amplification. Any point of current change between these extremes may also be used with good effect.Type: GrantFiled: August 22, 2007Date of Patent: March 31, 2009Assignee: Delphi Technologies, Inc.Inventors: Michael P. Cooke, Adrian R. Tolliday

Patent number: 7509947Abstract: A fuel pump for use in an internal combustion engine comprises a pump housing provided with a plunger bore, a pumping plunger which is movable within the plunger bore by means of a cam drive arrangement to perform a pumping stroke to pressurise fuel within a pumping chamber and a cam follower arrangement interposed between the cam drive arrangement and the pumping plunger so as to transmit a drive force of the drive arrangement to the pumping plunger. The cam follower arrangement includes a timing advance piston for advancing or retarding the timing of the pumping stroke, and control means for controlling the timing advance piston so as to advance or retard the timing of the pumping stroke. The timing advance piston is provided with a groove on its outer surface for receiving fluid, thereby to provide a centralising force to the timing advance piston, in use.Type: GrantFiled: March 15, 2007Date of Patent: March 31, 2009Assignee: Delphi Technologies, Inc.Inventors: Onur Mehmet Tansug, George N Felton

Patent number: 7509948Abstract: A spacer for use with, and to prevent or reduce the occurrence of stiction in, a fluid device such as a pump. The spacer has a generally ring-shaped body, which has first and second facing surfaces separated by a thickness. The spacer is positioned between a movable member of the pump and a stationary member of the pump such that the first facing surface of the spacer is contactable with the movable member and the second facing surface is contactable with the stationary member. The spacer has at least a fluid receiving groove formed in at least one of the first and second facing surfaces.Type: GrantFiled: October 1, 2007Date of Patent: March 31, 2009Assignee: Caterpillar Inc.Inventors: Jeffrey M.
