Patent number: 6378502Abstract: An improved fuel injection valve for a high-pressure injection of fuel from a central high-pressure line into combustion chambers of an internal combustion engine, which has an injection valve with a valve seat, a valve ball, and a guide piece that guides the valve ball. The guide piece presses the valve ball against the valve seat in order to close the injection control valve and during the opening, subjects the valve ball to an initial stress of a spring. During the opening, the valve ball is lifted up from the valve seat by means of a high-pressure jet which is supplied via an outlet throttle bore by a control chamber that is operatively connected with a central high-pressure line. A diffuser is disposed between the valve seat and the outlet throttle bore, and the outlet throttle bore, the diffuser, and the valve seat have the approximate shape of a steep-walled funnel with a right-angled to acute-angled cone angle.Type: GrantFiled: October 2, 2000Date of Patent: April 30, 2002Assignee: Robert Bosch GmbHInventor: Lorenz Betz

Patent number: 6371084Abstract: A fuel injection valve for high-pressure injection of fuel from a high-pressure reservoir into a combustion chamber of an internal combustion engine, especially a diesel engine, is described. The fuel injection valve has a magnet valve by means of which the fuel pressure can be either relieved (injection position) or built up (closing position) in a control chamber via a throttle having at least one throttle conduit segment defined by conduit walls. According to the invention, the throttle conduit segment is embodied substantially in the form of a variable aperture, or a variable throttle aperture.Type: GrantFiled: May 15, 2000Date of Patent: April 16, 2002Assignee: Robert Bosch GmbHInventor: Lorenz Betz

Patent number: 6276335Abstract: A fuel injection valve for high-pressure injection of fuel from a central high-pressure line into combustion chambers of an internal combustion engine, which includes a switching valve with a valve seat and a valve ball; the valve ball in the opened state is lifted from the valve seat by means of a high-pressure jet which is supplied from a throttle bore by a pressure chamber operatively connected to a central high-pressure line. The transition from the throttle bore to the valve seat is embodied as a diffuser.Type: GrantFiled: December 17, 1999Date of Patent: August 21, 2001Assignee: Robert Bosch GmbHInventors: Walter Egler, Peter Boehland, Lorenz Betz, Ralf Hentschel
