Claims

[Scope of Claim for Utility Model Registration] Piping that communicates with a tank on one side and is connected to a hose with a refueling nozzle at the tip on the other side, a pump installed in the middle of the piping and driven by a pump drive motor, and a flow rate. a flow meter that measures the flow rate, a refueling amount calculation means that calculates the flow rate pulse output from a flow pulse transmitter attached to the flowmeter and displays the refueling amount on a refueling amount display, and the refueling nozzle is in a storage position. a refueling work start detecting means for detecting separation from the refueling work start signal and outputting a refueling work start signal; and starting the pump driving motor by inputting the refueling work start signal output from the refueling work start detecting means; a first refueling control means for resetting the refueling amount indicator to zero; and after the pump drive motor is started by the first refueling control means, refueling is performed by the refueling nozzle for a predetermined period of time. When the refueling work is not being carried out, a refueling interruption/end detection means detects the interruption or end of the refueling work, and a second stop of the pump driving motor is provided by inputting a detection signal output from the refueling interruption/end detecting means. a refueling control means; a refueling continuation switch provided in the middle of the refueling nozzle or hose; and when the pump drive motor is stopped by the second refueling control means, an operation signal from the refueling continuation switch. a third oil supply control means for restarting the pump drive motor in response to an input from the pump drive motor;
