A discharge hole is formed in the sealing plate, and the diaphragm is driven in accordance with the flow of pressurized fluid into the container, and the stem slides, thereby increasing the amount of pressurized fluid discharged from the cylinder. It is characterized by being regulated.

<Embodiments> Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a partially cutaway side view showing an embodiment of the present invention, and FIG. 2 is an enlarged sectional view of the main part. This pouring device is designed to pour beer B stored in the beer barrel 1 out of the beer barrel 1 by injecting carbon dioxide gas into the beer barrel 1.

This pouring device includes a cylindrical stopper 4 assembled to the outer periphery of the mouth 2 of the barrel 1 via a sealing material 3;
It has a cylindrical holder 6 that holds a small cylinder 5 filled with liquefied carbon dioxide gas (75 kg/cm ² ) so as to stand up on the stopper 4 . The lower end of the holder 6 is screwed onto the outer periphery of a cylindrical portion 7 formed upright on the stopper 4.

A cylindrical partition member 9 with a through hole 8 formed in the center is attached and fixed inside the upper end of the holder 6, and this partition member 9 separates the inside of the holder 6 into a first chamber 10 and a second chamber. It is divided into two chambers 11. The cylinder 5 is housed and held in the first chamber 10 with the sealing plate 5A positioned on the upper side.

The second chamber 11 is located on the outer periphery of the upper end of the holder 6.
A cylindrical cap body 12 is rotatably screwed to seal the body.

A stem 13 made of soft rubber is tightly fitted into the through hole 8 of the partition member 9 so as to be slidable in the axial direction of the holder 6. A cylinder opening needle (sharp object) 14 is assembled and fixed at the center of the stem 13. The nail 14 protrudes from the lower end of the stem 13, and a seal member 15 made of soft rubber and integrally formed with the stem 13 is disposed around the outer periphery of the tip of the needle 14.

A diaphragm 16 made of soft rubber and integrally formed with the stem 13 is disposed at the upper end of the stem 13, and an outer peripheral portion 16A of the diaphragm 16 is provided.
is supported by the inner peripheral wall of the second chamber 11, and the second chamber 11 is divided into a diaphragm upper chamber 11A and a diaphragm lower chamber 11B.

The stem 13, seal member 15 and diaphragm 16 are integrally formed of soft rubber as shown in FIG.

The stem 13 includes the first chamber 1.
0 and the diaphragm upper chamber 11A are formed through the four communication passages 17 in the axial direction. Also,
A projection 18 is provided at the center of the inner surface of the cap body 12, which engages with the upper end of the stem 13 and causes the tip of the cylinder opening needle 14 to enter the first chamber 10.

Next, the operation of the pouring device having the above configuration will be explained.

As shown in FIG. 4, when the cap body 12 is tightened, the protrusion 18 engages with the upper end of the stem 13, and the cylinder opening needle 14 is pushed toward the first chamber 10 side. In this way, when the needle 14 is pushed in, the tip of the needle 14 enters the first chamber 10, and the sealing plate 5A of the cylinder 5 accommodated in the first chamber 10 is penetrated by the needle 14. Therefore, a discharge hole 5a having a small opening diameter is formed. When the tip of the needle 14 is inserted into the sealing plate 5A, the sealing member 15 is inserted into the sealing plate 5A.
Since the discharge hole 5a is in pressure contact with the discharge hole 5a, no carbon dioxide gas is discharged from the discharge hole 5a. Note that when the cap body 12 is tightened as described above and the discharge hole 5a is bored in the sealing plate 5A, the outer circumference of the holder 6 is inserted into the annular groove 19 provided on the inner circumference of the cap body 12. The protruding annular locking portion 20 is designed to fall down and engage.

When the cap body 12 is loosened as shown in FIG. 5, the stem 13 slides upward in the figure due to the restoring force of the diaphragm 16, and the sealing member 15 is separated from the sealing plate 5A. Thereby, a gap is formed between the sealing member 15 and the sealing plate 5A. Note that the cap body 12 is connected to the annular groove 1.
9 is engaged and locked by the annular locking portion 20 of the holder 6, so that it can only be loosened halfway.

In this way, when a gap is formed between the sealing member 15 and the sealing plate 5A, the carbon dioxide gas in the cylinder 5 is squeezed by the needle valve action of the needle 14 protruding into the discharge hole 5a. The carbon dioxide gas in the first chamber 10 flows out into the first chamber 10 through the groove 9A formed on the lower surface of the partition member 9, and the carbon dioxide gas in the first chamber 10 flows into the first chamber 10 as shown by the arrow in FIG. a groove 21 formed in the inner circumferential wall of the chamber 10, a groove 22 formed in the inner circumferential wall of the cylindrical portion 7, and the plug body 4.
The gas is supplied into the barrel 1 through a gas supply hole 23 formed in the barrel 1. By supplying carbon dioxide gas into the barrel 1, the beer B in the barrel 1 is poured out through the vinyl pipe 24 due to the pressure of the carbon dioxide gas. Note that the carbon dioxide gas in the cylinder 5 is also supplied to the diaphragm upper chamber 11A via the communication path 17.

By the way, the area of the diaphragm 16 and the stem 13 facing the diaphragm upper chamber 11A is the slam 13.
The area of the sealing member 15 facing the first chamber 10 is larger than that of the sealing member 15 . Therefore, if the flow of carbon dioxide gas in the barrel 1 is stopped for some reason, the upper chamber 11 of the diaphragm is removed as shown in FIG.
As the diaphragm 16 is displaced and driven by the pressure of the carbon dioxide gas A, the stem 13 slides downward in the figure, and the sealing member 15 comes into pressure contact with the sealing plate 5A. As a result, the discharge hole 5a of the sealing plate 5A is sealed, and the discharge of carbon dioxide gas in the cylinder 5 is stopped. Therefore, it is possible to prevent the inside of the barrel 1 from becoming abnormally high pressure, and it is possible to reliably prevent the stopper 4 from being blown off or the barrel 1 from being destroyed, resulting in excellent safety.

In addition, if a load is applied to the flow of carbon dioxide gas in the barrel 1 by restricting the amount of beer B poured out through the vinyl pipe 24, the carbon dioxide gas is supplied to the diaphragm upper chamber 11A through the communication passage 17. Gas is repeatedly supplied and released, and the diaphragm 16 is driven according to the pressure of carbon dioxide gas in the diaphragm upper chamber 11A. This allows stem 1
3 reciprocates in the vertical direction in FIG.
The amount that the tip of the carbon dioxide gas enters the discharge hole 5a is adjusted, and the amount of carbon dioxide gas discharged can be adjusted. Therefore, the pressure inside the barrel 1 can always be kept constant, and the pouring power of beer B can be kept constant.
