ABSTRACT:
One spring and two spring embodimenls of a fuel injection having a nozzle body and needle valve with cooperating inner and outer metering rings providing a metering passage which (a) meters fuel at a reduced rate during an initial increment of valve lift, (b) assists in maintaining fuel pressure at the valve seat to reduce fuel dribble and cavitation erosion during a corresponding last increment or valve closure and (c) dampens secondary pressure waves to prevent secondary fuel injection.
