ABSTRACT:
An electromagnetically operated fuel injection valve structured to include a housing having a fuel inlet opening, a fuel discharge opening and a fuel return opening, there being a continuous liquid path from the inlet opening to the return opening and an intermittent, or valved, liquid path from the inlet opening to the discharge opening. The continuous liquid path has a slope, in the direction of flow toward said return opening, which preferably is always 0 or positive relative to a horizontal axis or plane. A discharge valve is provided in the injector and exists in the valve path. The discharge valve is connected to an armature which is in turn actuated by a solenoid comprised of a coil, a tubular bobbin and an electromagnetic frame. The frame has a vertical tubular core portion and an upper flange extending outwardly therefrom. The coil is disposed on the bobbin and the bobbin is coaxially disposed about the frame core portion below the flange. The flange, and preferably also the core of the frame include a slot or opening extending therethrough. The continuous liquid path extends upwardly through the frame tubular core and, in parallel, through the opening in the upper flange.
