A liquid supply pump 42 driven by a pump motor 43 is configured to feed liquid stored in an underground tank or the like to the nozzle body 1 via a flow meter 41. The flow rate pulse transmitter 44 connected to the flow rate pulse generator 44 is configured to output a pulse signal to a control device M5o, which will be described later, and display it on a display 46.

れでいる。FIG. 4 shows details of the above-mentioned control drawing 5o.
The liquid supply control device 50 includes a liquid supply stop detection means 51 that outputs a signal to a timer 52 and a motor control means 53 when the pulse signal from the flow rate pulse transmitter 44 is cut off; The clock means 52 outputs a signal to the control means 53 to operate the pump motor 43 after a preset time has elapsed, and the nozzle switch 45 operates the pump motor 43 and controls the supply. The pump motor 43 is stopped by a signal input from the liquid stop detection means 51, and furthermore, the timing means 5
The motor control means 53 is configured to receive, for example, 3 or 4 signals from 2, for example, 3 or 4 times, and it is assumed that the liquid supply has ended, and no further signals will be accepted.The motor control means 53 is reset by signals from the nozzle switch 45, and the flow rate pulse is A counting means 54 integrates the flow rate pulses from the transmitter 44 and outputs the integrated value to the display 46 via the display driving means 55.
つぎに上述した装置による給液動作を第2図に基づいて
説明する。Next, the liquid supply operation by the above-mentioned apparatus will be explained based on FIG. 2.
給液ノズル本体1が計量装置140のノズル掛け49に

縁ヲバイロット弁14に当接させ、弱いバネ13に抗し
てパイロット弁14を押上げている。When the liquid supply nozzle main body 1 is hung on the nozzle hook 49 of the metering device 140, that is, when the liquid supply pump 42 is stopped and the lever 30 is not operated,
As shown in FIG. 2(i), the movable valve seat 19 is biased by the strong spring 17 and comes into contact with the back surface of the main valve 16 to close its own flow path opening 18, and at the same time closes the main valve]6. The upper edge of the push-up is brought into contact with the pilot valve 14, and the pilot valve 14 is pushed up against the weak spring 13.

はそのまま閉塞された状態を保つ(第2図(ii))。In this state, for example, when the nozzle body 1 is removed from the nozzle hook 49 in order to fill the fuel tank of a car with gasoline, a signal from the nozzle switch 45 causes the control device 5 to
The zero counting means 54 is reset to make the display 46 zero, and at the same time, the pump/motor 43 drives the liquid supply pump 42 and enters a liquid supply operation. Therefore, the movable valve seat 19 and the main valve 16, which had been raised due to the force of the spring 17, fall under the hydraulic pressure from the liquid supply pump 42 while remaining in contact with each other, and along with this, the weak spring The pilot valve 14 energized by the valve 13 also moves downward, and the flow passage opening 18 of the movable valve seat 19
remains in the occluded state (Fig. 2 (ii)).

1内はこの時点で大気圧となっている。Next, insert the tube tip 2 into the liquid supply port of the tank, pull the lever 30, and hook the latch 31, and the lever 3o
The valve rod 12 pushed up first pushes up the pilot valve 14 against the weak spring 13, and forms a gap between it and the main valve 6, which is pushed down by the hydraulic pressure, and from there, the pilot valve 14 is pushed up against the weak spring 13. Hole 15
The liquid flows to the downstream side via , lowering the hydraulic pressure, and then pushing up the main valve 16 to open the flow path gap 018 provided in the movable valve seat 19 (
Figure 2 (iii)). Therefore, the liquid sent by the liquid supply pump 42 flows from the negative pressure generating section 7 of the check valve 6 to the cylinder tip section 2, and further flows from there into a tank (not shown). On the other hand, when liquid supply is started in this way, negative pressure is generated in the negative pressure generating part 7 of the check valve 6 due to the Venturi effect, and the inside of the air flow path pipe 5 opened here is made negative pressure. , since the mouth end of the pipe 5 on the cylinder tip 2 side is in the atmosphere and sucks air, the negative pressure chamber 2 of the automatic valve closing mechanism 20
1 is at atmospheric pressure at this point.

(1V))。As the liquid level in the tank rises due to subsequent liquid supply, and eventually the open end of the cylinder tip 2 is blocked by the bubbles on the liquid level, the inside of the negative pressure chamber 2 communicating with the air flow pipe 5 becomes a negative pressure due to the negative pressure action in the negative pressure generating part 7, and the diaphragm 23, which is deformed by this negative pressure,
2 was pulled up and the sliding rod 26 was locked through the small ball 24.
Release the lock. As a result, the lever 30, whose free end is locked in the notch 31, loses its fulcrum by the sliding rod 26, so it falls down due to the biasing force of the spring 13 acting on the pilot valve 14, lowering the main valve 16 together with its back surface. The flow path opening] 8 is closed by contacting the movable valve seat 19 (FIG. 2 (1V)).

れる(第2図(V ))。In this state, the liquid supply stop detection means 51 immediately detects this liquid supply stop, and based on the signal, the timer 52
At the same time, a signal is sent to the motor control means 53 to cause the control means 53 to stop the pump motor 43. Therefore, the movable valve seat 19 whose hydraulic pressure has been released rises together with the main valve 16, the pilot valve 14, and the valve rod 12 integrated therewith due to the urging force of the strong spring 17, and on the other hand, the lever 3
The sliding rod 26, which is released from the downward force exerted by the valve rod 2 through the valve rod 07a, rises due to the biasing force of the spring 25 acting on itself, and the diaphragm 23 returns to its normal state when the liquid supply is stopped.
The small ball 24 is again locked by the locking rod 22 integrated with the locking rod 22 (FIG. 2(V)).

これにより、筒胴部3内に流入した液はバネ17に抗し

6 and open the flow path opening 188, returning to the liquid supply state again (FIG. 2 (1ii)).

せる。After this fluid supply restart operation, the mouth end of the air flow pipe 5 on the pipe tip 2 side is closed again by the millet, and the automatic valve closing mechanism 2o that operates at the same time lowers the valve rod 12 via the lever 30. , the main valve 16 lowered together with the pilot valve 14
When the liquid supply is stopped by touching the movable valve seat 19 (second
(Fig. 1V)) After that, the scissoring operation is repeated to perform intermittent liquid supply. When this operation is repeated several times, the motor control means 53 considers that the tank is full, and stops the pump motor 43 without receiving any further signals from the timer means 52 to stop all the supply. Terminate liquid operation.

ように構成してもよい。By the way, in the above explanation, the main liquid supply and the additional liquid supply are performed with the same discharge amount, or the discharge amount from the liquid supply nozzle body 1 is adjusted by the signal from the timing means 52, for example, 45A during the main liquid supply. /min, 25A'/min at the first additional liquid supply, 15β/min at the second additional liquid supply.
The number of rotations of the pump motor 43 may be changed so that the number of rotations of the pump motor 43 becomes min.

停止動作を行なわせるようにすることもできる。Furthermore, in this embodiment, the pump motor 43 is stopped in response to a signal from the liquid supply stop detection means 51 to stop the liquid supply, or a control valve is installed in the pipeline system from the liquid supply pump 42 to the nozzle body 1. It is also possible to provide a control valve and cause the liquid feeding stop operation to be performed by this control valve.
