BACKGROUND OF THE INVENTION
The present invention relates to an oil supply device that supplies fuel oil to an automobile.
[0002]
[Prior art]
There are two types of fuel oil for automobiles: gasoline and light oil, and regular and premium respectively. When gasoline and light oil are mixed and supplied to an automobile, engine troubles will occur. However, regular and premium oils will not cause engine problems when mixed in small quantities. These oils are put in separate oil storage tanks and supplied to the automobile through a pump and a flow meter. The flowmeter used in this fueling device is required to have a high level of measurement accuracy and is relatively large and expensive. Therefore, the oil supply device is large and expensive.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. As shown in FIG. 1, the inlets of pumps 2a and 2b provided in the housing 1 of the fueling device are connected to oil storage tanks 4a and 4b via fueling pipes 3a and 3b. The outlets of the pumps 2a and 2b are connected to the inlet of the flow meter 6 via the oil supply pipes 5a and 5b, and check valves 7a and 7b are interposed in the oil supply pipes 5a and 5b. The outlet of the flow meter 6 is connected to an oil supply hose 9 through oil supply pipes 8a and 8b, and on-off valves 10a and 10b and check valves 11a and 11b are interposed in the oil supply pipes 8a and 8b. An oil supply nozzle 12 is attached to the tip of the oil supply hose 9, and a nozzle switch 14 is provided on the nozzle hook 13 of the oil supply nozzle 12.
[0009]
The on / off signal of the nozzle switch 14 provided on the nozzle hook 13, the flow signal of the flow rate pulse transmitter 15 provided on the flow meter 6, and the selection signal of the oil type selection button 16 provided on the housing 1 are oil supply control. Input to the device 17, a drive signal to the pumps 2 a and 2 b, a valve opening signal to the on-off valves 10 a and 10 b, and a display signal to the oil supply amount indicator 18 are output from the oil supply control device 17. .
[0010]
Next, the operation will be described based on the flowchart of FIG. Regular gasoline is stored in the oil storage tank 4a, and high-octane gasoline is stored in the oil storage tank 4b. If the customer who has come to refueling wants regular gasoline, the refueling nozzle 12 is removed from the nozzle hook 13, an ON signal is input from the nozzle switch 14 to the refueling control device 17 (ST1), and the oil type selection button 16 When the regular gasoline is designated from (ST2), the display of the previous oil amount displayed on the oil amount indicator 18 is returned to zero, the on-off valve 10a is opened, and the pump 2a is driven (ST3). When the oil supply nozzle 12 is inserted into the vehicle oil supply port and the nozzle valve is opened, the regular gasoline in the oil storage tank 4a is supplied to the oil supply pipe 3a, the pump 2a, the check valve 7a, the oil supply pipe 5a, the flow meter 6, and the oil supply pipe 8a. Then, the fuel is discharged from the oil supply nozzle 12 through the on-off valve 10a, the check valve 11a, and the oil supply hose 9.
[0011]
The flow rate pulse from the pulse transmitter 15 of the flow meter 6 is input to the oil supply control device 17, and the calculated oil supply amount is displayed on the oil supply amount display 18.
[0012]
When the desired amount of fueling is finished, the fueling nozzle 12 is hooked on the nozzle hook 13 and an off signal is input from the nozzle switch 14 to the fueling control device 17 (ST4), the on-off valve 10a is closed and the driving of the pump 2a is stopped ( ST5) All refueling operations are completed.
[0013]
When refueling high octane gasoline, the refueling nozzle 12 is removed from the nozzle hook 13 (ST1), and high octane gasoline is designated by the oil type selection button 16 (ST6).
Thereby, the display of the previous oil supply amount displayed on the oil amount indicator 18 is returned to zero, the on-off valve 10a is opened, and the pump 2a is driven. Then, opening the nozzle valve of the fueling nozzle 12, high-octane gasoline in the oil storage tank 4b is discharged from the dispensing nozzle 12 in a manner similar to the regular gasoline as described above, and, flow meter 6 from the pulse generator 15 of the The flow rate pulse is input to the oil supply control device 17, and the calculated oil supply amount is displayed on the oil supply amount display 18. (ST7, ST8, ST9).
[0014]
As shown in FIG. 3, the interior of the oil supply hose 9 is defined as sections 9a and 9b . The oil supply pipe 8 a is connected to the section 9 a of the oil supply hose 9, and the oil supply pipe 8 b is connected to the section 9 b of the oil supply hose 9. By doing so, the amount of mixed oil can be reduced.
[0015]
Moreover, in embodiment mentioned above, although pump 2a, 2b is provided in the housing 1 of a fueling apparatus, you may provide a submerged pump in oil storage tank 4a, 4b. Furthermore, in the above-described embodiment, the example of two oil types has been described, but the present invention can be similarly applied to a multi-oil type of two or more oil types.
[0016]
