Patent number: 7316385Abstract: A lightweight, low cost throttle body and throttle valve placed in the body, both formed of resins, that resolve the problem of excessively large gap formation is disclosed. Circumferentially oriented filler contained in a resin forming a throttle valve compensates to make the radial linear expansion coefficient of the throttle valve substantially equal to that of a bore. Grooves are formed on concentric circles in the throttle valve to orient filler circumferentially. A throttle valve provided with circumferentially oriented filler can be formed by impregnating an aggregate formed by circumferentially arranging the filler with a resin and curing the resin. A rib is formed in a part near a throttle shaft to control molding shrinkage so that the roundness of the bore is small.Type: GrantFiled: November 14, 2005Date of Patent: January 8, 2008Assignees: Hitachi, Ltd., Hitachi Car Engineering Co., Ltd.Inventors: Naozumi Hatada, Makoto Iida, Yutaka Takeuchi, Shigeo Tamaki

Patent number: 7243635Abstract: The invention is intended to simplify a default mechanism of a throttle valve opening and closing device for the purpose of improving mountability of the device to a vehicle. When a motor generate no driving forces, a throttle valve is held in a position (1) by a return spring. In this position, gaps are formed between the throttle valve and a wall surface of an intake passage. Spherical recesses are formed in parts of the wall surface of the intake passage. In a position (2) where the throttle valve is opposed to the spherical recesses, the gaps are minimized in an operating range of the throttle valve.Type: GrantFiled: April 19, 2005Date of Patent: July 17, 2007Assignee: Hitachi, Ltd.Inventors: Masahiko Soshino, Takehiko Kowatari, Yuzo Kadomukai, Yuki Ejiri, Kenji Ono, Yasuhiro Kamimura, Norihiro Isozaki, Eisuke Wayama, Hitoshi Andoh, Yutaka Takeuchi
