Abstract
A fuel injection nozzle has an outer body member and an inner body member, the inner body member being slidingly positioned in a secondary axially extending cavity in the outer body member and including a valve needle slidingly positioned in a primary axially extending cavity in the inner body member. The inner body member acts as a first fluid pressure actuated valve needle for injecting fluid between the inner member and the outer member when the inner member is displaced axially by fluid pressure. The valve needle acts as a second fluid pressure actuated valve member for injecting fluid through an extension of the second axially extending cavity when the valve needle is displaced axially by other fluid pressure. First fluid orifices extend through an end of the outer member for spraying fuel released by displacement of the inner body member. Second fluid orifices extend through an end of the inner member for spraying fuel released by displacement of the valve needle.
