Abstract
A fuel injection nozzle includes a fuel pressure actuated valve member of the inwardly opening type which is movable by the action of fuel under pressure away from a seating to allow fuel flow from a nozzle inlet through an outlet. Mounted on the nozzle body is a spill valve which when operated allows fuel to escape from the nozzle inlet so as to lower the fuel pressure applied to the nozzle valve member. The spill valve is actuated by hydraulic means.
