Claims

[Claims for Utility Model Registration] (1) A refueling nozzle includes a nozzle body that has a fluid flow path inside and a discharge pipe that communicates with the fluid flow path on the tip side, and a valve mechanism consisting of a bubble detection sensor and a liquid detection sensor, a main valve body and an auxiliary valve body that are located in the middle of the fluid flow path and are provided in the nozzle body, and are opened and closed by operating an operating lever; , when the bubble detection sensor detects bubbles while the valve mechanism is opened by the operating lever, the main valve body is opened and only the auxiliary valve body is kept open. It consists of a flow rate adjustment mechanism that reduces the discharge amount by
A refueling device further comprising: a refueling stop mechanism that performs a final refueling stop when the liquid detection sensor detects a liquid level while the discharge amount is being throttled by the flow rate adjustment mechanism. (2) The refueling device according to claim (1), wherein the refueling stop mechanism is a solenoid valve or a pump provided in the middle of a flow path connected to the refueling nozzle.
