SACK-LOCK IMPORTS FOR FUEL-RAPPING MACHINERY TRANSFERRING BETWEEN SACK-LOCK AND DOUBLE SIDE

摘要

An injection nozzle with a blind bore is disclosed in which the transition between the blind bore and the nozzle needle seat is rounded. This decreases the tolerance in the flow resistance of the injection nozzle upon a partial stroke of the nozzle needle, and thus makes a more-precise control of the injected fuel quantity possible.
