Abstract
Disclosed is a fuel injection valve () comprising a control member () that is provided with a control passageway () which is arranged eccentrically relative to the housing axis () and can be opened and closed by a closure piece () with the aid of an actuator assembly () in order to obtain intermittent injections. The control member () is positioned by means of a centering pin () in order to define the circumferential position of the eccentric control passageway (). The centering pin () is guided within a pocket bore of the control member () as well as within a bore of an intermediate plate (), a cylindrical element (), or a spacing sleeve (). The actuator assembly () is designed as an electromagnetic actuator () in which the stop () for limiting the lift of the pilot valve member is designed as a monolithic component of the intermediate plate () or as a flat stop disk () in a separate workpiece. The eccentric position of the actuator assembly () and the design of the stop () allow for a very compact design of the fuel injection valve. The compact design makes it possible to mount a suitable storage chamber in the monolithic housing body () of the fuel injection valve, above the high-pressure inlet bore ().
