Abstract
An inwardly opening fuel injection nozzle includes a first spring which is coupled by means of a push rod to the valve member of the nozzle. The nozzle includes a second spring positioned between the first spring and the valve member and acting upon a slidable abutment member which is engaged by the valve member after a predetermined movement of the valve member away from a seating. The valve member is lifted against the first spring by fuel under pressure supplied to an inlet to allow restricted fuel flow through an outlet and further against the action of both springs as the pressure at the inlet increases to allow unrestricted flow through the outlet.
