Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refueling system for refueling an automobile, and more particularly to a refueling system which can suitably use an attendant refueling system in which a worker at a gas station refuels and a self-lubricating system in which a customer himself refuels. It concerns the device.

[0002]

2. Description of the Related Art A measuring device is provided in a horizontally long main body case.
An oil supply device provided with an oil supply hose having an oil supply nozzle attached to one end of a main body case and a fuel supply amount indicator fixed to the other end of the main body case is known as Japanese Patent Application Laid-Open No. 8-72995. Since the refueling amount indicator of the refueling device is provided at a position away from the refueling nozzle and faces the side of the refueling device, the refueling amount indicator is easy to see for the customer in the driver's seat of the car, and is suitable for attendant refueling. . However, in self-refueling which is about to spread, there is a disadvantage that a refueling amount indicator is difficult to see for a refueling customer.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a refueling device having a refueling amount indicator which is easy for a customer to see in both attendant refueling and self-refueling.

[0004]

In order to achieve the above object, the present invention provides a weighing device provided in a horizontally long main body case,
In a refueling device provided with a refueling hose having a refueling nozzle attached to the end at one end on the main body case and a refueling amount indicator provided at the other end on the main body case, the refueling amount indicator is provided on the side of the refueling device. Since it is horizontally rotatable between the first position facing, the second position facing obliquely rearward of the refueling device, and the third position facing almost directly behind, in the case of attendant refueling Sets the refueling amount indicator to the first position, and in the case of self-refueling, sets the refueling amount indicator to the first position or the third position to provide a refueling device having a refueling amount indicator that is always easy for the customer to see.

[0005] A detector for detecting the position of the refueling nozzle, a rotating mechanism for rotating the refueling amount indicator, a rotating control device for receiving a signal from the detector and driving the rotating mechanism, Attendant refueling and self-refueling setting means are provided, and when the attendant refueling is set, the refueling amount indicator is fixed at the first position, and when the self-refueling is set, the refueling amount indicator changes to the second position. Since it rotates between the third position, in the case of self-refueling, the refueling amount indicator automatically turns to a position that is easy to see for the refueling customer.

The detector for detecting the position of the refueling nozzle outputs a detection signal when a wire of a retractor for pulling up and urging an intermediate portion of the refueling hose through a wire is pulled out by a certain amount or more. The dynamic control device receives the input of the detection signal from the detector and the refueling start signal input when refueling is started, and receives the signal for rotating the refueling amount indicator to the second position, and performs the rotation. Output to the mechanism, receiving a non-input of the detection signal from the detector and a refueling start signal input when refueling is started, and a signal for rotating the refueling amount indicator to the third position is received. Since the output is sent to the rotating mechanism, the refueling amount indicator rotates at the position of the refueling nozzle at the start of refueling, and is not affected by hose loosening until refueling starts. There is no rotation.
