Abstract

A fuel injection nozzle for supplying fuel to an internal combustion engine includes a valve member biased by a spring against the action of fuel under pressure supplied to an inlet. A further spring acts in opposition to the first mentioned spring through a piston like push piece. The fuel pressure also acts upon the push piece in opposition to the force exerted by the further spring and the extent of movement of the push piece under the action of the further spring is limited.
