Out of the main body case, and a hose provided with a refueling nozzle at the end is connected to the outflow pipe.

[0003]

Since the suction pipe of the pump uses a hollow pipe, when the oil supply device is moved to another oil storage container, the oil in the suction pipe flows out and contaminates the surroundings. If the oil in the suction pipe spills out,
Until the inside of the suction pipe is filled with oil, the pump efficiency deteriorates, and further, there is a disadvantage that the air is measured to cause a measurement error.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the prior art and to prevent the oil in the suction pipe from flowing out when the oil supply device is moved to another oil storage container, and to reduce the flow resistance during oil supply. An object of the present invention is to provide a refueling device provided with a pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to an oil supply device mounted on a pail as an oil storage container for measuring oil. As shown in FIGS. 1 and 2, a main body case 2 of an oil supply device is mounted on an oil storage container 1 containing 20 liters of oil. In the main body case 2, a pump 4 driven by a motor 3 is provided.
A flow meter 6 connected to an outflow pipe of the pump 4 and provided with a flow pulse transmitter 5, a display 7 for displaying the amount of refueling measured by the flow meter 6, and a refueling measured by the flow meter 6. A printer 8 for printing the amount on the slip is provided.

As shown in FIG. 3, the suction pipe 10 of the pump 4
An opening / closing valve 13 urged by a spring 12 is provided in a valve chamber 11 provided at the lower end of the valve.
Is protruded downward from the valve chamber 11, and when the main body case 2 is placed on the oil storage container 1, the valve rod 14 contacts the bottom of the oil storage container 1, and the opening / closing valve 13 is sucked so as to open apart from the valve seat 15. The length of the tube 10 is determined. Above the inflow port 16 of the valve chamber 11, a liquid level sensor 17 for detecting immediately before the oil reservoir 1 becomes empty is provided. This liquid level sensor 17
Is composed of a float 18 lighter than the liquid in the oil storage container 1 and a switch 19 that is closed by the float 18 that descends when the liquid runs out.

An outflow pipe 21 of the flowmeter 6 is led out of the main body case 2, and a hose 23 having an oil supply nozzle 22 provided at the end thereof is connected to the outflow pipe 21. The oil supply nozzle 22 is provided on the upper surface of the main body case 2. It can be hung on the nozzle hanger 24. Nozzle mount 24 has refueling nozzle 22
Is provided with an oil supply switch 25 that opens and closes when the battery is removed. In addition, in this embodiment, since it is mounted on a cylindrical pail can having a height of about 40 cm, the main body case 2 of the refueling device has a cylindrical shape with an upper surface formed obliquely and a lower portion. Is formed with a rim 26 which engages with the oil reservoir 1, and on the upper surface, a display 7 and a printer 8 are provided.
And a nozzle hook 24 are arranged.

A control device 30 connected to each of the above-described devices is provided in the main body case 2.
Receives the start signal from the refueling switch 25 when the refueling nozzle 22 is removed from the nozzle hook 24, returns the previous refueling amount displayed on the display 7 to zero, and starts the motor 3 that drives the pump 4. During refueling, the pulses from the flow rate pulse transmitter 5 are counted and displayed on the display 7, and the refueling nozzle 22
The motor 3 is stopped in response to an end signal from the refueling switch 25 when is applied to the nozzle hook 24, and the printer 8 is activated to issue a slip on which the refueling amount is printed. Also,
When the liquid in the oil storage container 1 runs out, the motor 3 is stopped in response to a signal output from the switch 19 of the liquid level sensor 17 and has a function of turning on the notification lamp 28. Then, the electric power to each of the above-described devices is input through the electric wire 29.

Next, the operation will be described. When the refueling nozzle 22 is detached from the nozzle hook 24 and a start signal is input from the refueling switch 25 to the control device 30, the control device 30 displays the previous refueling amount displayed on the display unit 7. And the drive motor 3 of the pump 4 is started. When the oil supply nozzle 22 is inserted into the oil supply container and the valve of the oil supply nozzle 22 is opened, the oil in the oil storage container 1 flows into the valve chamber 11 from the inflow port 16,
The flow pulses discharged from the refueling nozzle 22 via the suction pipe 10, the pump 4, the flow meter 6, and the hose 23 and from the flow pulse transmitter 5 of the flow meter 6 are counted and displayed on the display 7. At this time, the valve rod 14 is in contact with the bottom of the oil storage container 1 and the on-off valve 13 is open, so that the pipeline resistance does not increase. After refueling is over, refuel nozzle 22
When it returns to 4, the end signal is output from the refueling switch 25, the motor 3 is stopped, and a slip on which the refueling amount is printed is issued from the printer 8.

When the amount of oil in the oil storage container 1 decreases due to refueling, the float 18 descends and the switch 19 closes, and upon receiving this signal, the control device 30 stops the motor 3 and turns on the notification lamp 28. As a result, the air is not measured, and it can be seen that the oil storage container is empty. When the oil storage container 1 becomes empty, the oil supply device is moved to another oil storage container. When the main body case 2 is lifted from the oil storage container 1, the contact of the valve rod 14 is released, and the on-off valve 13 is seated on the valve seat 15 by the spring 12 and closed. Thus, the oil in the suction pipe 10 does not flow out, and no air enters the suction pipe 10. And if it puts on the oil storage container containing oil, a refueling operation can be performed.
