Disclosed is a fuel dispensing gun which can supply oil vapor generated from an inside of a fuel tank of a vehicle to the inside of the fuel tank again by recovering the oil vapor through an oil vapor recovering means installed in an inside of a fuel dispensing nozzle. In the fuel dispensing gun including a main body connected to a body of a lubricator and the fuel dispensing nozzle, a collection cover having a shape of a pocket which is opened in a front end direction of the fuel dispensing nozzle and is closed in a rear end direction of the fuel dispensing nozzle is installed around the fuel dispensing nozzle, a venturi tube includes an inlet portion, an outlet portion, and a neck portion having a diameter smaller than the inlet portion and the outlet portion to form a vacuum portion in a predetermined position in a longitudinal direction in the inside of the fuel dispensing nozzle by changing the pressure of the fuel in the fuel dispensing state along the longitudinal direction of the fuel dispensing nozzle, and the vacuum portion and the inside of the collection cover are connected with each other by a connecting means. Thereby, the oil vapor between an inside of a fuel charging tube and the collection cover is recovered in the inside of the fuel tank of the vehicle by the vacuum portion formed in the inside of the venturi tube. |
