Claims

[Scope of utility model registration request]

a nozzle body provided with a discharge pipe and an operating lever, an oil passage formed within the nozzle body, one end of which is connected to the oil supply hose and the other end communicates with the discharge pipe; A valve body that opens and closes a passage, a diaphragm chamber disposed within the nozzle body and defined by a diaphragm, and an atmosphere with one end opening toward the tip of the discharge pipe and the other end opening into the diaphragm chamber. An introduction passage, a negative pressure passage whose one end communicates with the diaphragm chamber and whose other end communicates with a negative pressure generating section provided in the middle of the oil passage, and the diaphragm chamber is in a negative pressure state due to blockage of the atmospheric air introduction passage. In an automatic stop nozzle comprising an automatic valve-closing mechanism that closes the valve body in response to the displacement of the diaphragm, when the diaphragm is displaced, a flow from the atmospheric air introduction passage to the negative pressure generating section is provided. An automatic stop nozzle characterized in that a closing valve is provided that closes the negative pressure passage in response to displacement of the diaphragm in order to prevent atmospheric air from flowing out.
