The electro-magnetic needle valve, for fuel injection in internal combustion engines, has an armature needle provided with at least two channels for passage of fuel towards the valve seat.
<??>A usually constructed electro-magnetic needle valve has an armature section (36) of larger diameter than the integral needle section (38). The needle section closes the valve seat at its lower end. Fuel is directed towards the valve seat through a pair of bores (60) in the enlarged armature section (36).
