ABSTRACT:
A fuel injection valve comprises a hollow body in which there is formed a fuel circuit having an outlet opening. A guide member has a stem located in the passage and secured to the body. A bulged end portion of the guide member projects through the opening and is formed with a valve seat surface. An annular valve closure member is slidably mounted on the guide member and sealingly movable in the opening. A coil in the body is adapted to move a valve closure member into an abutment position clear from the seat. When the valve closure member is in that open position, a conical jet of fuel is delivered by the valve.
