Patent number: 9617961Abstract: A fuel injector for an internal combustion engine having an elongated body with a fuel inlet end and a fuel discharge end. The injector body includes an outwardly extending plate attached at a position between its ends and this plate includes at least one radially outwardly extending tab so that the cross-sectional shape of the plate is noncircular. A fuel cup receives the fuel inlet end of the fuel injector and includes a radially inwardly extending ledge at a mid position of the cavity. This ledge includes a through bore complementary in shape to the shape of the plate so that, with the fuel injector and plate aligned at a predetermined angular assembly position, the plate passes through the ledge upon insertion of the fuel injector into the cavity. Thereafter, rotation of the fuel injector and attached plate to a locking position positions the tabs above the ledge thus locking the fuel injector to the fuel cup.Type: GrantFiled: July 22, 2014Date of Patent: April 11, 2017Assignee: HITACHI AUTOMOTIVE SYSTEMS AMERICAS, INC.Inventors: William T. Harvey, Steven J. Miller, Hiroaki Saeki

Patent number: 8555858Abstract: A high pressure fuel pipe construction for an internal combustion engine, such as a direct injection engine. A conduit for the fuel is open at each end and a ball having a throughbore is slidably positioned over one end of the conduit. A reinforcing sleeve is positioned inside the end of the conduit so that the sleeve extends entirely through the ball. The sleeve, ball and the end of the conduit are then brazed together to attach the ball and conduit together. A double chamfer is provided at one end of the ball throughbore to facilitate inspection of the brazing quality. Additionally, a loop is formed in the conduit and a dampener is attached to the loop.Type: GrantFiled: September 20, 2011Date of Patent: October 15, 2013Assignee: Hitachi, LtdInventors: Harsha Badarinarayan, Akira Inoue, Takashi Yoshizawa, Atsushi Hohkita, Hiroaki Saeki, Hiroshi Ono, Masahiro Soma, William T.

Patent number: 6205979Abstract: A fuel rail assembly comprising a fuel rail and a damper assembly in the fuel rail. The damper assembly includes a damper having an end and an inner surface defining a cavity, and a sealing member at least partially received in the end and bonded to the inner surface to substantially seal the cavity. The sealing member is preferably a metal wire that includes a sealing portion bonded to the inner surface to substantially seal the cavity. The bond is preferably formed by induction brazing, and the sealing member is coated with copper to facilitate the brazing. The invention also provides a fuel rail assembly comprising a fuel rail having a longitudinal axis and an inner wall. A damper assembly in the fuel rail includes a damper, and a spring locator coupled with the damper, the spring locator having two positioning portions outwardly biased to engage the inner wall of the fuel rail and position the damper assembly axially in the fuel rail. The spring locator is preferably a metal wire.Type: GrantFiled: November 24, 1999Date of Patent: March 27, 2001Assignee: Robert Bosch CorporationInventors: Dewey M. Sims, Jr., Paul L.
