Embodiments of the present invention will be described below. As shown in FIGS. 1 and 2, the capacity of the oil storage container 3 of the oil supply device is about 20 liters. You can do it freely.

A case 7 is placed on the oil reservoir 3 and is detachably fixed by a clamp 6. A discharge pipe 9 of a measuring pump 8 located in the oil reservoir 3 is connected to a bottom plate 10 of the case 7.
It is fixed to. The measuring pump 8 has a driving motor 1
1 and a flow pulse transmitter 12 are provided integrally, and a plurality of liquid level sensors 17 are attached along the discharge pipe 9. In addition, the motor 11 is provided in the case 7,
The motor 11 and the measuring pump 8 may be connected by a conduction shaft.

A valve chamber 13 is provided at the inlet of the measuring pump 8, and the on-off valve 1 urged closed by a spring 14 is provided in the valve chamber 13.
The valve rod 16 of the on-off valve 15 projects below the valve chamber 13, and when the case 7 is installed on the oil storage container 3, the valve rod 16 contacts the bottom of the oil storage container 3, and the on-off valve Fifteen
The length of the discharge pipe 9 is determined so as to open apart from the valve seat.

The discharge pipe 9 fixed to the bottom plate 10 of the case 7
Is drawn out of the case 7 and the refueling nozzle 21 is
The hose 22 to which is attached is connected. The refueling nozzle 21 is provided only with a check valve 23 at the tip, and does not have a manual opening / closing valve provided in a conventional refueling nozzle. The refueling nozzle 21 is provided with a nozzle switch 24 of the motor 11 for driving the measuring pump 8.

A display 25, a printer 26, and a refueling switch 27 are provided on the front of the case 7, and a control device 30 connected to each of the above-described devices is provided inside. Then, commercial power is supplied to the control device 30 via the power supply line 28.

As shown in FIG. 3, the control device 30 includes a correction coefficient storage unit 31 storing the relationship between the liquid level and the correction coefficient (see FIG. 4), and the liquid level from the liquid level sensors 17, 17,. A correction coefficient selection unit 32 that receives a signal and selects a correction coefficient stored in the correction coefficient storage unit 31, and a calculation unit 33 that calculates a flow rate based on a flow rate signal from the flow rate pulse transmitter 12 and the selected correction coefficient. Receiving the closing signal of the refueling switch 27, returns the previous count value to zero, integrates the calculated value from the calculating means 33, and outputs the integrated value to the display 25; Motor driving means 35 which receives a closing signal from the nozzle switch 24 and outputs a driving signal to the motor 11 in a state where the closing signal is input.
And a printer driving unit 36 that receives an open signal from the refueling switch 27 and outputs the integrated value of the integrating unit 34 to the printer 26.

Next, the operation will be described with reference to the flow chart of FIG. 5. When the refueling switch 27 is pressed and a close signal is input to the control device 30 (ST1 in FIG. 5), the previous time accumulated in the accumulation means 34 is calculated. Refueling amount is reset and display 2
5 is returned to zero (ST2 in FIG. 5), and the motor driving means 35 enters a standby state. When the refueling nozzle 21 is inserted into the refueling container and the nozzle switch 24 is pressed (FIG. 5 ST
3), a driving signal is output from the motor driving means 35 to the motor 11 (ST4 in FIG. 5).

Then, the measuring pump 8 is driven by the motor 11 and the oil in the oil storage container 3 is supplied from the inlet to the valve chamber 13.
It is sent to the refueling nozzle 21 via the measuring pump 8, the discharge pipe 9, and the hose 22.

During the refueling operation, the correction coefficient selecting means 32 receives the liquid level signals from the liquid level sensors 17, 17,..., Selects the correction coefficient stored in the correction coefficient storage means 31, and calculates the correction coefficient. I tell 33. For example, when the inside of the oil reservoir 3 is full and the liquid level signal from the liquid level sensor 17 at the uppermost stage is input, the liquid level is 50 Cm or more, the correction coefficient is selected to be 1.026, and the calculating means 33 is selected. It is transmitted to. The calculating means 33 multiplies the flow pulse from the flow pulse transmitter 12 by a correction coefficient and outputs the value to the integrating means 34. For example, if the amount represented by the flow pulse is 5 milliliters, every time one pulse is input, 5 × 1.026
= 5.130 (milliliter) is output to the integrating means 34. Then, this value is integrated by the integrating means 34, output to the display 25 and displayed. When the liquid level decreases with refueling and the signal from the uppermost liquid level sensor 17 disappears, the correction coefficient (1.019) corresponding to the liquid level at the next stage is
It will calculate.

When the container to be supplied becomes almost full, the user releases the nozzle switch 24 and opens the nozzle switch 24 (ST5 in FIG. 5).
And the motor 11 of the measuring pump 8 stops (ST6 in FIG. 5). When refueling is continued, the nozzle switch 24 is closed again to refuel (FIG. 5 ST).
7, ST8). In addition, since the refueling nozzle 21 is provided with the check valve 23 when refueling is stopped, dripping is prevented.

When the refueling is completed, the refueling nozzle 21 is removed from the refueling container and the refueling switch 27 is opened (FIG. 5).
ST7), the refueling amount accumulated by the accumulating means 34 from the printer driving means 36 is output to the printer 26 (FIG. 5).
ST9) A slip on which the refueling amount is printed is issued from the printer 26.

When the oil storage container 3 is empty, the clamp 6 is released, and the case 7 is removed from the oil storage container 3 to supply oil. At this time, the contact of the valve rod 16 is released, and the on-off valve 15 is seated on the valve seat and closed by the spring 14, so that the oil in the valve chamber 13 and the measuring pump 8 does not flow out. Then, after replenishing oil to the oil storage container 3, the case 7 is again moved to the oil storage container 3.
And clamp 6 is performed.
