Abstract
A fuel injection nozzle has a valve member engageable with a seating to prevent fuel flow through an outlet orifice. The valve member is engaged by the narrower end of a stepped piston member the surface of which remote from the valve member is subjected to fuel under pressure to bias the valve member into engagement with the seating. A tubular valve element the interior of which is connected to a drain, is engageable with the surface but can be moved away from the surface to lower the pressure applied to the surface. The valve member lifts away from the seating when the pressure applied to the surface is reduced by fuel pressure acting on a further surface defined on the valve member. The valve element is connected to the armature of a solenoid.
