負圧を、同ノズルＡ先端近傍に設けた連通孔２７
から流入される空気のみにてブレークしておき、
タンクに給油した燃料油が連通孔２７に達した際
、同孔２７から流入される流体が空気から燃料油
に切替わる際に生ずる負圧上昇により、開放状態
でロツクした同ノズルＡの給油弁２のロツクを解
除し、同弁２を閉鎖して自動的に給油を停止すべ
く構成したオートストツパー付の給油ノズルＡに
おいて、エジエクター部２０からの負圧導出孔２
４を同エジエクター部２０の下半部にのみ配設し
てなるオートストツパー付給油ノズルの負圧導出
孔配設構造。 An ejector part 20 is provided in the internal flow path of a refueling nozzle A for supplying fuel oil to a tank of a vehicle, etc., and the negative pressure generated in the ejector part 20 during refueling is communicated near the tip of the nozzle A. Hole 27
Break only with the air flowing in from the
When the fuel oil supplied to the tank reaches the communication hole 27, the refueling valve of the nozzle A is locked in the open state due to the negative pressure rise that occurs when the fluid flowing in from the hole 27 switches from air to fuel oil. In the refueling nozzle A with an auto stopper configured to automatically stop refueling by releasing the lock of the valve 2 and closing the valve 2, the negative pressure outlet hole 2 from the ejector part 20
4 is disposed only in the lower half of the ejector part 20, and a negative pressure outlet hole arrangement structure of a refueling nozzle with an auto stopper is provided.
