The material offers improved surface finish and deformation resistance as well as improved thermal conduction and keeps thermal expansion low as compared to conventional fuel injector tip seal designs. According to a further aspect, a revised seal groove design is provided that allows for expansion and deformation of the tip seal and creates more pressure to the outside diameter face when pressure is applied at the tip. According to another aspect, the tip seal is formed of a flat disk-shaped seal body that can be assembled on the fuel injector by an assembly cone device that allows the disk-shaped seal body to be flipped to a ring-shaped configuration in its assembled position.Type: GrantFiled: June 21, 2007Date of Patent: January 5, 2010Assignee: Freudenberg-NOK General PartnershipInventors: Gregory J.

Patent number: 7640918Abstract: The invention relates to a drive circuit for an injector arrangement having a fuel injector, and a method of detecting faults in the drive circuit. The drive circuit includes a diagnostic tool that senses a measured voltage between the injector and a known voltage level. The measured voltage is biased with respect to the known voltage to a predicted voltage unless the drive circuit has a fault. A fault signal is provided on sensing of a measured voltage that differs from the predicted voltage. The drive circuit may additionally, or alternatively, include a diagnostic tool. The diagnostic tool senses a detected current to provide a fault signal upon detection of the fault when the detected current is at variance from a threshold current.Type: GrantFiled: April 3, 2007Date of Patent: January 5, 2010Assignee: Delphi Technologies, Inc.Inventors: Louisa Perryman, Nigel P. Baker, Steven Martin, Martin A. P. Sykes

Patent number: 7640919Abstract: A fuel system is disclosed. The fuel system has a first pump supplying fuel at a first pressure. The fuel system also has a fuel filter fluidly connected downstream of the first pump. The fuel system further has a second pump receiving fuel at a second pressure and fluidly connected downstream of the fuel filter. The fuel system additionally has a first passage fluidly connecting an outlet of the first pump to an inlet of the first pump. The fuel system also has a valve located within the first passage and configured to selectively allow fuel flow through the first passage. The fuel system further has a second passage fluidly connecting an inlet of the second pump to the valve, wherein the second pressure acts on the valve to affect fuel at the first pressure to flow to the inlet of the first pump via the first passage when the second pressure is greater than a predetermined pressure.Type: GrantFiled: January 31, 2008Date of Patent: January 5, 2010Assignee: Perkins Engines Company LimitedInventor: Paul John Smith

Patent number: 7640920Abstract: The present invention includes a first canister disposed within an intake air passage. The first canister communicates with a fuel tank via a second canister, so that a fuel vapor produced within the fuel tank can be purged by the second canister and further by the first canister. The second canister communicates with the intake air passage via a purge passage. The negative pressure within the intake air passage may be applied to the first and second canisters via the purge passage, so that the fuel vapor adsorbed by the first and second canisters can be desorbed or purged and can then be returned into the intake air passage.Type: GrantFiled: September 25, 2008Date of Patent: January 5, 2010Assignee: Aisan Kogyo Kabushiki KaishaInventor: Katsuhiko Makino

Patent number: 7640921Abstract: An injector bracket 10 is provided inside an air cleaner 5. The injector bracket 10 comprises a rectifying wall 10a bulging into a main chamber 5b, and a stream-line guide wall 10b in opposition to an air current M having passed through an element 8. The injector bracket 10 functions as a partition and forms a separate chamber 10e partitioned from the main chamber 5b in the air cleaner 5. An upstream injector unit 7 is arranged in the separate chamber 10e. The rectifying wall 10a is in the form of a symmetric blade.Type: GrantFiled: November 22, 2004Date of Patent: January 5, 2010Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Tsugunori Konakawa, Mitsutoshi Koide, Hiroaki Ito, Takahiro Ozawa

Patent number: 7640923Abstract: A hidden sensor structure for a paintball gun is to secure a loader unit on a hopper of a barrel. A loader is used to hold against the loader unit. The loader unit has arcuate slots to receive resilient stoppers therein, with studs protruding from the resilient stoppers to extend into the hopper. A sensor has an emission end, a receiving end, and a socket. The sensor is coupled to the loader unit from the bottom of the barrel, with the emission end and the receiving end inserting into two troughs formed on two sides of the load unit and the socket engaging with a fixture of the loader unit.Type: GrantFiled: December 3, 2008Date of Patent: January 5, 2010Inventor: Yi-Tsong Chen

Patent number: 7640924Abstract: A feeding mechanism for ball bullets from a bin to a holder. The mechanism contains a bin 1 and additional reservoir 2 which in a lower part communicate. A vibrator 3 is placed in the lower part of the bin 1 and the additional reservoir 2. The vibrator 3 is formed of two plates 4 and 5 of L-shape that oscillate on the axis 6 due to spring 7 and cam 8, which is rotated by the electric drive 9. A feeding screw mechanism is disposed in the lower part of the bin 1 and the additional reservoir 2, the mechanism comprising a screw 10 with a helical spring. The base 12 is connected to cam 8 through a friction coupling 13. The cam 8 gains rotation from the electric drive 9 through the gearing 14. The bin 1 with additional reservoir 2 communicates with the holder 16 through the channel 15.Type: GrantFiled: September 6, 2006Date of Patent: January 5, 2010Assignee: Federalnoe Gosudarstvennoe Unitarnoe Predpriyatie “Izhevsky Mekhanichesky Zavod”Inventor: Valery Leonidovich Cherepanov

Patent number: 7640925Abstract: A pneumatic assembly for a paintball gun preferably includes a bolt slidably arranged on a valve stem. The bolt is preferably moveable between an open and a closed position. The bolt preferably provides a firing mechanism for the paintball gun by permitting compressed gas from a compressed gas storage area to flow through the bolt to fire the paintball gun when the bolt is closed but preventing the transfer of compressed gas through the bolt when the bolt is open. An internal area of the valve stem can be arranged to communicate with the compressed gas storage area to increase the effective volume of the compressed gas storage area without increasing the size of the paintball gun. This can permit lower pressure operation of the paintball gun. A supply of compressed gas to the compressed gas storage area can be cut off during firing to improve gas efficiency.Type: GrantFiled: March 14, 2006Date of Patent: January 5, 2010Assignee: Smart Parts, Inc.Inventor: Danial Jones

Patent number: 7640926Abstract: A pneumatic assembly for a paintball gun preferably includes a bolt slidable between an open and a closed position. The bolt preferably provides a firing mechanism for the paintball gun by permitting compressed gas to flow through the bolt to fire the paintball gun when the bolt is closed but preventing the transfer of compressed gas through the bolt when the bolt is open. This can be accomplished, for instance, by arranging a sealing member in communication with a surface of the bolt. A port is also preferably arranged through a lateral sidewall of the bolt at a predetermined location. The bolt preferably slides in relation to the sealing member such that when the bolt is open, the sealing member prevents compressed gas from flowing into the forward end of the bolt, but when the bolt is closed, compressed gas is permitted to flow into the forward end of the bolt to launch a paintball. The bolt is preferably controlled by using a control valve such as a three-way solenoid valve to operate a pneumatic piston.Type: GrantFiled: December 16, 2005Date of Patent: January 5, 2010Assignee: Smart Parts, Inc.Inventor: Danial Jones
