ABSTRACT:
An accumulator type of fuel injection nozzle having an injection valve that is controlled by an electromagnet within the accumulator chamber includes a feeder wire structure formed axially in the outer housing assembly of the injection nozzle for energizing the electromagnet. This feeder wire structure includes one or more axially extending wire passages formed in the outer housing assembly, preferably in a structure through which is formed a fuel inlet conduit, constructed so as to withstand the high pressure within the accumulator chamber, to provide a sufficient seal without increasing the outer diameter of the injection nozzle, and to provide easy installation of the injection nozzle without interference from the engine. One or more feeder wires are contained within the wire passages for energizing the electromagnet.
