Abstract
An accumulator type of fuel injection nozzle including an improved arrangement for slidably supporting the actuator end of the injection valve within the control chamber that controls the opening and closing of the injection valve. This is accomplished by providing a closure plate that has a large diameter bore that supports an enlarged diameter end portion of the injection valve. The bore is closed by a slidably supported supporting plate that has a smaller diameter bore which engages the control valve adjacent its larger diameter portion and slidably supports it.
