たことを特徴とする給油ノズル。A built-in valve to which the discharge pipe is connected opens and closes the flow path in the nozzle body, a negative pressure generation chamber that communicates with this flow path and generates negative pressure by the flow of oil in the flow path, and this negative pressure chamber. A valve closing mechanism that automatically closes the built-in valve in conjunction with a diagram that is displaced in response to the negative pressure generated in the pressure generation chamber, and a negative pressure generation chamber that is normally communicated with the atmosphere outside the flow path to generate negative pressure. In a nozzle equipped with a negative pressure compensating path for compensating and preventing the negative pressure compensating frame, and a closing body for closing the negative pressure compensating frame depending on the inclination angle of the nozzle, the flange and main body connect the discharge pipe and the main body to the inflow end of the discharge pipe. The flange surface formed at the outflow end of the main body is connected to the main body flange surface by sandwiching the plate-shaped packing, and the main body flange surface is connected to the negative pressure compensating path on the main body side, and the closure body chamber accommodates and holds the closure body. The packing is characterized by having an elongated hole narrower in width than the obturator so that the obturator chamber and the negative pressure compensator on the discharge pipe side communicate with each other through this elongate hole.
