Abstract

PURPOSE:To fill a tank with fluid by only one feeding operation, by repeatedly making a halt of fluid feeding for a certain internal at a fluid feeding nozzle which is provided with the first valve displacing a position to pass the fluid by the fluid pressure and the second valve to close its path by a liquid level indicator. CONSTITUTION:When a lever 30 is pulled to hook a latch 31, a valve stem 12 raises a pilot valve 14 and a main valve 16 opens a passage opening 18 equipped at a movable valve sheet 19. When the liquid level in the tank rises and the opening end of the nozzle 2 is closed due to foam on the liquid level, the inside of a vacuum chamber 21 connected to an air passage tube 5 becomes negative and a diaphragm 23 lifts up a stopping bar 22 to relieve a hold of a sliding bar 26. The main valve 16 contacts the movable valve sheet 19 to close the passage opening 18. Form disappears and a pump motor is started by a signal from a timer. Again the opening end of the nozzle 2 of the air passage tube 5 is closed by foam and an automatic valve closing mechanism 20 lowers the valve stem 12 via the lever 30 and the main valve 16 contacts the movable valve sheet 19 to make a halt of fluid feeding. Thereafter, this motion is repeated to feed the fluid and the pump motor is stopped.

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.

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)).

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.

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)).

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)).
