ABSTRACT:
A fuel injection nozzle unit includes a plate in which is formed an orifice through which fuel can flow to be mixed with air flowing to the engine. The plate defines a surface for engagement by a disc-like valve member formed from magnetizable material and which is urged into contact with the surface by fuel under pressure which may be assisted by a spring. A core member has a face presented to the aforesaid disc and in which is formed a plurality of grooves extending about the aforesaid outlet. The grooves accommodate electrical windings which are connected in such a manner that the current flow in the windings in adjacent grooves, so that the face of the core presented to the disc forms a series of pole pieces of opposite magnetic polarity. The magnetic field moves the disc away from the aforesaid surface to permit flow of fuel through the outlet.
