1. An oil filling nozzle with a vapor recovery function comprising:
a discharge pipe; a vapor control valve arranged in a middle of a pipe which connects a vapor collector mounted so as to cover a circumference of the discharge pipe and a vapor passage, said vapor control valve being opened and closed by liquid pressure in a main body of the nozzle, the vapor control valve including:
a valve seat; anda valve element moveable relative to the valve seat, the valve element being seated against the valve seat when the vapor control valve is closed and being spaced from the valve seat when the vapor control valve is open, the valve element including a first tapered surface associated with a first opening degree of the vapor control valve and a second tapered surface associated with a second opening degree of the vapor control valve; and an adjuster configured to adjust a vapor recovery rate by adjusting an opening degree of the vapor control valve. |
