Next, the operation of the apparatus of this embodiment configured as described above will be explained.

If the target to be refueled is located away from the predetermined refueling position on the main body 1 of the refueling device, remove the refueling nozzle 29 from the nozzle hook 30 and pull the tip of the hose 28 in the direction of the target. Since it is attached to the movable tube 19 via the rotation tube 22 and the elbow joint 25 so as to be rotatable in the horizontal and vertical directions, the base end side of the hose 29 also faces in the direction to which the oil is to be supplied. When the hose 28 is further pulled in the direction of the refueling object in this state, the moving tube 19 is pulled by the hose 28 and slides on the guide tube 12, so that the movement range of the refueling nozzle 29 is expanded.

Next, a case will be described in which the oil in the tank is supplied from the refueling nozzle 28 to an object to be refueled. The oil sucked up from the tank by the pump 8 flows into the guide pipe 12 from the elbow joint 15 via the flow meter 9 and the fixed pipe 6. The oil outlet 18 of the guide tube 12 and the flow path A formed between the guide tube 12 and the moving tube 19 are always in communication regardless of the position to which the moving tube 19 has moved. Therefore, the oil inside the guide tube 12 flows through the oil outflow port 18 and the flow path 18.
A, the rotation pipe 22 and the elbow joint 25 can be sequentially flown, and the target can be refueled from the hose 28 through the refueling nozzle 29.

According to the device of this embodiment, the proximal end of the hose 28 is connected to the elbow joint 25, and the elbow joint 25 is rotatably connected in the vertical direction to the rotation tube 22, and the rotation tube 22 is connected to the movement tube 19. Since the hose 28 is connected so as to be rotatable in the lateral direction, the hose 28 can maintain a straight line and pull the transfer pipe 19. As a result, the hose 28 is not twisted or locally bent, and the flow of the oil in the hose 28 is prevented from being obstructed and the hose 28 is prevented from being damaged. Further, the guide tube 12 has a bellows 21
Since it is configured to be covered with AA and 21A, it is possible to prevent the smooth sliding of the transfer pipe 19 from being inhibited by rust caused by rainwater or the like or by the adhesion of dust. Further, the guide tube 12 is constructed in a dual-supported type in which one end 12A is supported by the side plate 2 via the fixed member 13, and the other end 12B is supported by the fixed pipe 6 via the elbow joint 15. When the guide tube 19 is moved, the guide tube 12 does not swing, and the moving tube 19 can move smoothly. Furthermore, in the device of this embodiment, the base of the hose 28 is supported so as to be rotatable laterally around the joint pipe portion 19B of the moving pipe 19, so the nozzle hook 30 is located at the center position of the right side plate 2. As a result, the refueling nozzle 29 can be easily taken out from either the front or rear sides of the refueling device main body 1.

In this embodiment, a single type fixed type oil supply system having one oil supply mechanism inside the oil supply apparatus main body 1 was explained as an example, but a double type fixed type oil supply system having two sets of oil supply mechanisms inside the oil supply apparatus body 1 was explained as an example. Of course, it can also be applied to

As explained in detail above, the present invention has a guide pipe connected to a fixed pipe on the outside of the casing that houses the main body of the oil supply system, and has an oil outlet in the center, and the base end of the hose is connected to the fixed pipe. Since the hose is configured to be connected to a movable tube that slides while being guided by a guide tube, the hose can be moved laterally, and the refueling range is expanded.
Furthermore, since the hose moving mechanism is provided outside the main body of the oil supply device, assembly and maintenance of the oil supply device can be easily performed. Furthermore, by providing a guide pipe on the fixed piping of the conventional fixed hose type oil supply device located on the outflow side of the flow meter, the conventional fixed hose type oil supply device can be easily changed to the oil supply device of the present invention. .
