Patent number: 7497202Abstract: A damper element for damping pressure pulsations in a liquid includes a first side including a first wall portion at least partially defining a chamber containing a gas and a second side including a second wall portion at least partially defining the gas-containing chamber. The second side is overlappingly joined with the first side such that the first and second wall portions combine to define substantially an entire cross-section of the gas-containing chamber. Both the first and second wall portions are convexly curved outwardly away from the gas-containing chamber.Type: GrantFiled: December 13, 2007Date of Patent: March 3, 2009Assignee: Robert Bosch GmbHInventors: Derek Cvengros, Dewey M. Sims, Jr., Hursha Shankaranarayan

Patent number: 7493892Abstract: A self-damping fuel rail for a fuel-injected internal combustion engine includes an elongated tube defining a wall and having a longitudinal axis. The wall defines a fuel passageway and has a first wall portion movable between a first position bowed inwardly toward the longitudinal axis when the self damping fuel rail is in a non-operative state, and a second position moved outwardly away from the longitudinal axis when the self-damping fuel rail is in an operative state. The self-damping fuel rail also includes at least one fuel outlet configured to facilitate communication between the fuel passageway and a fuel injector.Type: GrantFiled: December 27, 2007Date of Patent: February 24, 2009Assignee: Robert Bosch GmbHInventors: Dewey McKinley Sims, Jr., Hursha Shankaranarayan

Patent number: 7385326Abstract: A throttle body assembly including an end plate. The throttle body assembly includes a housing having an inner wall, and a motor located within the housing. The motor end plate is coupled to the motor and is in contact with the inner wall of the housing. The end plate includes an outer edge having at least one protrusion extending therefrom. The contact between the end plate and the housing is substantially only between the at least one protrusion on the outer edge of the end plate and the inner wall of the housing.Type: GrantFiled: December 29, 2005Date of Patent: June 10, 2008Assignee: Robert Bosch GmbHInventors: Dewey M. Sims, Jr., Hursha Shankaranarayan

Patent number: 7341045Abstract: A damper for damping pressure pulsations in a liquid includes an outer tube having an inner surface defining an interior cavity, and an inner tube positioned within the interior cavity of the outer tube. The inner tube includes an outer surface such that at least one chamber is formed between the inner surface of the outer tube and the outer surface of the inner tube for containing a gas. The damper includes an exterior surface configured to be surrounded by the liquid and an interior surface configured to define a passageway through the damper for the liquid. The damper can define at least two, and in one embodiment, four separate chambers for containing a gas. The damper can be part of a fuel rail assembly and is positioned within a fuel rail configured to contain pressurized fuel.Type: GrantFiled: October 15, 2004Date of Patent: March 11, 2008Assignee: Robert Bosch GmbHInventors: Dewey M. Sims, Jr., Hursha Shankaranarayan
