ABSTRACT:
A fuel injection nozzle of the outwardly opening type includes a valve member having a head biased into contact with a seating by a coiled spring. Fuel under pressure applied to the valve member lifts the head from the seating to allow fuel flow through an outlet. The valve member has a spring retainer connected to it and which forms a piston slidable in a skirt member which forms a cylinder into and out of which fuel can flow through a port. The port is positioned to be progressively covered by the retainer member to form a hydraulic spring which assists the action of the coiled spring, as the valve head is lifted from the seating.
