Patent number: 6779743Abstract: In a fuel injection valve including a flat fuel diffusion chamber provided between a valve seat member and an injector plate to widen radially outwards from an outer end edge of a valve seat bore, an annular step is formed on a ceiling surface of the fuel diffusion chamber so that a level of the ceiling surface is gradually lowered radially outwards, and fuel injection orifices are disposed immediately below the step and at a distance from an inner peripheral wall of the fuel diffusion chamber. Thus, a fuel spread radially in the fuel diffusion chamber is allowed to collide with the annular step, leading to an enhancement in fuel diffusing effect, so that it is possible to further promote the atomization of the fuel injected from the fuel injection orifices and to form more stable fuel spray forms.Type: GrantFiled: June 19, 2003Date of Patent: August 24, 2004Assignee: Keihin CorporationInventor: Koji Kitamura
