Patent number: 10344722Abstract: The present disclosure relates to fluid injection and the teachings thereof may be embodied in an injector. Some embodiments include an injector comprising: a valve with a valve body and a valve needle; an armature mechanically coupled to the valve needle for moving the valve needle away from a closing position; and a damping element. The valve needle moves in the valve body and seals the valve. The armature displaces the valve needle away from the closing position. The damping element comprises: a hydraulic chamber and a piston arranged to modify a fluid volume of the hydraulic chamber. The piston reduces the fluid volume of the hydraulic chamber when the valve needle moves away from the closing position. A flow restricting orifice hydraulically connects the hydraulic chamber to the cavity.Type: GrantFiled: May 13, 2015Date of Patent: July 9, 2019Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Xaver Gebhardt, Daniele Carli, Christoph Hamann, Ivano Izzo, Anatoliy Lyubar

Patent number: 10174701Abstract: A method for detecting the commencement of opening of the nozzle needle of an injector of an injection system. In the detection method, the coil of the solenoid injector has a voltage applied to it which is so low that the armature is moved toward the nozzle needle at such a low speed that the abutment causes a stoppage of the armature movement, without the nozzle needle being opened. In this case, the idle travel is overcome, but no injection process is initiated. The abutment of the armature against the nozzle needle is detected, in the current profile, as the commencement of opening of the nozzle needle.Type: GrantFiled: March 5, 2015Date of Patent: January 8, 2019Assignee: Continental Automotive GmbHInventors: Frank Denk, Nikolay Belyaev, Christian Hauser, Anatoliy Lyubar, Gerd Roesel, Markus Stutika
