SOLUTION: In a refueling device 1 provided with a refueling hose 8, a refueling nozzle 9 and a nozzle holder 11 for refueling at least two oil types of a gasoline system A and a light oil system B, respectively, the refueling nozzle 9 of the gasoline system A and the light oil system B. Have different shapes.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fueling device installed in a gas station or the like for supplying fuel oil to an automobile.

[0002]

2. Description of the Related Art There are two types of fuel oil for automobiles: gasoline and gas oil. When gasoline is refueled with gasoline or gasoline is refueled, engine troubles occur and accidents and fires occur. There is a risk of occurring. In particular, a refueling device in which a gasoline system and a light oil system are incorporated in one case is convenient because one vehicle can refuel any vehicle, but there is a risk of refueling with the wrong oil type. For this purpose, the present applicant has disclosed in Japanese Patent Laid-Open No. 8-729.
As No. 96, gasoline and gas oil supply hoses,
We proposed a lubrication system that prevents erroneous lubrication by using different colors for the lubrication nozzle and the nozzle hook. However, since the only difference between the gas oil system and the gasoline system is the color that appeals to the eye, it was difficult to completely prevent erroneous refueling even with this refueling device.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lubricating apparatus which can discriminate the difference in oil type not only visually but also by sense, thereby preventing erroneous refueling.

[0004]

In order to achieve the above object, the present invention relates to a refueling hose including a refueling hose, a refueling nozzle, and a nozzle hook for refueling at least two oil types of a gasoline system and a light oil system, respectively. The shapes of the fuel nozzles of the gasoline system and light oil system are different. As described above, since the refueling nozzle is different between the gasoline system and the light oil system, the type of oil can be recognized by feeling when the refueling nozzle is grasped, and erroneous refueling can be prevented.

Since the oil supply hose, oil supply nozzle, and nozzle hook of the gasoline system and the light oil system have different colors, the oil type can be visually recognized, and erroneous oil supply can be prevented.

[0006]

Embodiments of the present invention will be described below. As shown in FIGS. 1 and 2, two cases of a gas oil supply system A and a gas oil supply system B are incorporated in a case 2 of the oil supply device 1.

A pump 5 driven by a motor 4 and a flow meter 7 provided with a flow pulse transmitter 6 are interposed in the oil supply pipe 3 of the gasoline oil supply system A. A refueling hose 8 is connected to the refueling pipe 3, and a refueling nozzle 9 is attached to a tip of the refueling hose 8. In addition, refueling pipe 3
Is connected to an oil supply pipe 10 from an oil storage tank (not shown) containing gasoline.

A nozzle hook 11 is provided on the front surface of the case 2 of the refueling device 1, and the nozzle hook 11 is provided with a nozzle switch 12 for detecting whether the refueling nozzle 9 is engaged.

The refueling control device 13 provided in the case 2 receives a signal output from the nozzle switch 12 when the refueling nozzle 9 is removed from the nozzle hook 11, and
The previous refueling amount displayed on the display 14 is returned to zero, a drive signal is output to the motor 4, and an oil type utterance signal of the refueling system is output to the alarm 15. Then, during refueling, the flow rate pulse signal from the flow rate pulse transmitter 6 is counted, the counted amount of refueling is displayed on the display 14, and is output from the nozzle switch 12 when the refueling nozzle 9 is put on the nozzle hook 11. Upon receiving the hanging signal, the driving signal to the motor 4 is stopped.

The fuel oil supply system B has the same structure as the gasoline oil supply system A, and a description thereof will be omitted.

The oil supply nozzle 9 of the gasoline oil supply system A and the oil supply nozzle 9 of the light oil oil supply system B have different shapes so that the oil type can be distinguished by feeling. Also, the nozzle hooks 11 for hooking the refueling nozzles 9 have different shapes to prevent crossover.

Further, the colors of the fuel hose 8, the scarf 9a covered on the fuel nozzle 9 and the nozzle hook 11 are different for each fuel system so that the oil type can be visually identified. For example, gasoline is red and light oil is yellow.

Further, the same effect can be obtained even if the entire shape of the refueling nozzle is the same for all oil types and the part that the person who refuels holds is different. For example, as shown in FIG. 3, the thickness of the grip portion 9b of the refueling nozzle 9 is changed or the grip portion 9b is changed.
By changing the uneven shape 9c, the type of oil may be identified by feeling.

[0014]

As described above, the present invention relates to a refueling device including a refueling hose, a refueling nozzle, and a nozzle hook for refueling at least two oil types of a gasoline system and a light oil system, respectively. The nozzles have different shapes. As described above, since the refueling nozzle is different between the gasoline system and the light oil system, the type of oil can be recognized by feeling when the refueling nozzle is grasped, and erroneous refueling can be prevented.
