Abstract | In an intermittent type swirl injection nozzle including a nozzle body having a through hole and a spray hole, a needle valve inserted into the through hole, and a partition member of a cylindrical shape fittedly and fixedly inserted into the through hole, a gap area between the needle valve and the partition member is increased in accordance with the lift of the needle valve. For this purpose, a tapered portion and a top end face are provided on the partition member in a manner that they contact with a tapered portion and a step portion provided on the needle valve when the needle valve is in a position to close the spray hole. The resultant injection nozzle has a variable injection rate and spray angle. |
