Abstract
A fuel injection nozzle for supplying fuel to an internal combustion engine is of the so-called outwardly opening type and has a valve head located in a pocket the wall of which is of right cylindrical form. A circumferential groove is formed in the wall of the pocket and fuel is communicated thereto by a further groove or grooves on the valve head. The valve head forms a first outlet communicating with the circumferential groove and through which on the initial lift of the valve head fuel flows to produce a low penetration fuel spray. As the head is further lifted ports in the valve head are exposed to the groove and these ports communicate with a central outlet in the head. A penetrative jet of fuel issues from the central outlet.
