And a beer introduction path (foamed beverage introduction path) 36 for introducing beer formed in the cock body 50 and supplied from the server body into the cock body 50. An elastic member 62 such as a coil spring is interposed between the valve stem 52 and the first valve body 60.
Packing member 58 made of rubber or the like attached to
Is pressed against a valve seat 56 formed in the beer supply passage 12 to ensure watertightness. Further, a liquid passage 52b is formed in the axial center of the valve rod 52, and a bubble passage 52a communicating with the liquid passage 52b penetrates in a radial direction. The bubble passage 52a is always provided with the packing member. It is closed by 58.

[0006] The above-described operation of discharging a beer server having a foaming function is performed by a beer discharging process shown in FIG. 6, and FIG.
Reference numeral 4 is at the stop position, in which neither beer nor foam is poured out. That is, before the operation of the operation lever 14, the first valve body 60 is attached to the valve seat 56 of the beer supply path 12 by the elastic member 6.
The seat 2 is seated under the pressure of the beer 2 and shuts off the supply of beer from the beer introduction path 36 to the beer supply path 12. The foam passage 52 a formed in the cock main body 50 is closed by a packing member 58. Therefore, the discharge nozzle 38

3 moves backward (to the right in the figure) in conjunction with it. Further, the valve stem 52 connected to the slider 53 and the first valve body 60 connected to the valve stem 52 also slide backward in conjunction with each other. At this time, the packing member 58 attached to the first valve body 60 is separated from the valve seat 56, the entrance of the beer supply path 12 is opened, and the beer introduction path 36 communicates with the discharge nozzle 38, and the beer is connected. Will be poured out. Then, after returning the operation lever 14 to the stop position as shown in FIG. 6C, the operation lever 14 is tilted backward to the bubble pouring position to perform bubble pouring as shown in FIG. 6D. Then, the slider 53, the valve stem 52, and the first valve body 60 slide forward on the contrary, and the packing member 58 is moved to the valve seat 56.
And the communication between the beer supply path 12 and the beer introduction path 36 is cut off. At this time, the elastic member 62 interposed between the first valve body 60 and the valve stem 52 is compressed, and the valve stem 52 slides further forward with respect to the first valve body 60, whereby the bubble passage is formed. 52a is opened. Therefore,
The beer introduced into the liquid passage 52b from the beer introduction passage 36 is foamed when passing through the foam passage 52a,
The obtained foam is discharged from the discharging nozzle 38.

As described above, by switching the tilting operation direction of the operation lever 14, only the beer can be poured out,
It is possible to foam by pouring the foam afterwards. However, as shown in FIG. 6 (e), after the foam is poured, the remaining foam 64 adheres to the beer supply path 12 and the pouring nozzle 38, and when the foam 64 drops into the next mug,
When the beer is poured out, the beer and the foam are mixed to generate a foaming phenomenon in which the liquid changes into a foam, so that a large amount of foam is generated and a so-called excessive foam state occurs. As a countermeasure for this, as shown in FIG. 6 (f), the operator tilts the operation lever 14 to the above-described beer dispensing position after the foam is dispensed, instantaneously performs beer dispensing again, and removes the remaining foam 64. A foaming operation for causing the foam to flow out together with the beer is performed to prevent the occurrence of the foam call phenomenon caused by dripping of the foam.

[0006]

As described above, a series of operations of the operation lever 14 for discharging beer and foam into the mug are performed by a sequence of "stop position (a) → beer discharge position (b) shown in FIG. ) → stop position (c) → foam pouring position (d) → stop position (e)
→ beer pouring position (f) (foaming operation) → stop position (a) ”, and it is necessary to tilt the operation lever 14 forward and backward with the stop position interposed. Further, there is a drawback in that the foaming operation needs to be performed instantaneously, and is greatly affected by the skill level of the operator.

A beer server that automatically pours beer into a mug 42 and then foams the beer as shown in FIG.
When the (foamed beverage dispenser) 40 is used, the above-described foaming operation is also performed automatically. However, as described above, the operation lever 14 needs to be tilted in the front-rear direction. The control and mechanism of the drive unit 44 for operating the motor 14 are complicated. Further, since the frequency of starting and stopping the drive motor increases, the cost increases and the durability decreases.
There is a problem of securing an installation place due to an increase in the size of the device.

[0018]

Next, the operation of the sparkling beverage pouring cock according to the embodiment will be described below. FIG. 2 shows a beer pouring operation process using the cock main body 10 incorporating the various valve mechanisms described above. In FIG. 2A, the operation lever 14 is at a stop position before the beer dispensing operation, and neither beer nor foam is dispensed. That is, before the operation of the operation lever 14, the first valve body 16 is pressed forward by the high-pressure beer supplied from the beer introduction path 36, and the packing member 32 adheres to the valve seat 26, and the beer is introduced from the beer introduction path 36. The supply of beer to the supply path 12 is shut off. Therefore, supply of beer and supply of foam to the pouring nozzle 38 are not performed.

As shown in FIG. 2B, the operation lever 1
4 is tilted forward to the beer discharging position, the valve body 15 moves backward in the beer supply path 12 and the first valve body 16 disposed in the valve body 15 is moved.

As a result, the packing member 32 is separated from the valve seat 26 so that the beer introduction path 36 and the discharge nozzle 38 communicate with each other, and the beer supplied from the beer introduction path 36 is discharged through the beer supply path 12 via the beer supply path 12. It is poured into a mug from 38. The second valve body 20 disposed on the valve body 15 also moves backward, but does not shut off the discharging nozzle 38 and the beer supply path 12 at the beer discharging position.

Next, as shown in FIG. 2 (c), when a foam pouring operation is performed in which the operating lever 14 is tilted from the beer pouring position to a foam pouring position further forward, the valve body 15 and the second The valve element 20 further moves backward in the beer supply path 12. At this time, the first valve body 16 also moves backward, so that the valve seat 2
6, the first valve body 16 is in a state in which the beer supply path 12 is continuously opened, but the second valve body 20 is moved backward, so that the beer supply path 12 and the discharging nozzle 38 are disengaged.
, That is, the communication state between the beer introduction path 36 and the discharging nozzle 38 is shut off by the second valve body 20, and the beer discharging is stopped. At this time, the bubble passage 23 formed in the valve body 15 is opened from the valve portion 17 of the cock body 10 and communicates with the pouring nozzle 38. Therefore, the beer supplied from the beer introduction passage 36 to the foam passage 23 through the through hole 28 of the first valve body 16 and the liquid passage 30 of the valve rod 18 has a fine texture when passing through the foam passage 23. The foam becomes foam, and the foam is post-poured from the pouring nozzle 38 into the beer stored in the mug. In other words, in the sparkling beverage pouring cock of the embodiment, beer and foam can be poured by simply operating the operation lever 14 forward,
There is no need to return to the stop position between each operation.

The bubble passage 23 is always closed by the valve portion 17 of the cock main body 10, and the operation lever 14 is tilted in the same direction beyond the beer pouring position to operate the second passage. Only when the valve body 20 interrupts the communication between the beer introduction passage 36 and the discharge nozzle 38, the foam passage 2
3 is configured to communicate with the discharging nozzle 38, so that no foam is discharged at the time of beer discharging, and conversely, no beer is discharged at the time of foam discharging.

As described above, when the stop operation of tilting the operating lever 14 backward to return the operating lever 14 to the stop position is performed after the foam is post-poured, the valve body 15, the first valve body 16 and the The two-valve element 20 moves forward in the beer supply path 12. At this time, the foam passage 23 is closed again by the valve portion 17 of the cock body 10 to stop foaming, and then the second valve body 2
The disconnection of the beer supply path 12 from the dispensing nozzle 38 due to 0 is released, and the beer dispensing position is established where the beer introduction path 36 and the dispensing nozzle 38 are in communication. Thereafter, when the first valve body 16 is seated on the valve seat 26, both the beer dispensing and the foam dispensing are completely stopped.

As described above, a predetermined amount of beer is dispensed by returning to the beer dispensing position while the operating lever 14 returns from the foam dispensing position to the stop position.
In addition, a foam flow for completely discharging the foam remaining in the discharge nozzle 38 together with the beer is performed. The operation lever 1
4 is automatically performed by the beer pressure applied to the first valve body 16, and the operator operates the operation lever 1 at the foam pouring position.
Just release your hand from 4. That is, the amount of beer supplied to the discharge nozzle 38 at the time of the above foaming is always constant, and it is possible to always provide constant quality beer without requiring the skill of an operator.

Further, the operation lever 14 is
In the beer server 40 automatically operated by (see FIG. 7), if the sparkling beverage pouring cock of the embodiment is adopted,
Since the operation direction of the operation lever 14 is only forward (one direction), the control and mechanism of the driving unit 44 are simplified, and the cost can be reduced. Further, the frequency of starting and stopping the driving motor in the driving unit 44 is reduced, and the durability can be improved.

[0025]

FIG. 3 shows a main part of a sparkling beverage pouring cock according to another embodiment. Since the basic structure is the same as that of the above-described embodiment, only different parts will be described. . In the sparkling beverage pouring cock according to another embodiment, the second valve body 21 is disposed on the rear side of the first valve body 16, that is, on the beer introduction path 36 side, and the front side in the enlarged diameter portion of the cock body 10. The conical recess is configured as the first valve seat 26, and the rear conical recess is configured as the second valve seat 33. An annular groove is formed at a required position of the second valve body 21 facing the second valve seat 33, and a packing member 27 such as an O-ring is provided in the annular groove. Further, a through hole 31 is formed in the first valve body 16 and the second valve body 20 so as to penetrate the center of the shaft. The through hole 31 communicates with the liquid passage 30 of the valve rod 18. I have.

When the operation lever 14 is at the stop position, the first valve body 16 is seated on the first valve seat 26 via the packing member 32 in a watertight manner as shown in FIG. The communication state between the beer supply path 12 and the beer supply path 12 is set to be cut off. Further, when the operating lever 14 is tilted further forward (in the same direction) beyond the beer discharging position to face the foam discharging position, as shown in FIG. It is set so as to be seated on the second valve seat 33 through the packing member 27 in a water-tight manner, so as to cut off the communication between the beer introduction path 36 and the beer supply path 12.

When the operation lever 14 is exposed to the beer discharging position, as shown in FIG.
6 and the second valve body 21 correspond to the corresponding valve seats 26, 3
3 and is connected to the beer introduction path 36 to the discharge nozzle 38 in a communication state to allow beer discharge. Further, when the second valve body 21 is seated on the second valve seat 33, the bubble passage 23 formed in the valve body 15 is opened,
The ability to pour out bubbles is the same as in the previous embodiment.

[0028]

Next, the operation of the sparkling beverage pouring cock according to another embodiment will be described below. As shown in FIG. 4A, in a state where the operation lever 14 is held at the stop position before the beer discharging operation, the first valve body 16 is moved forward by the high-pressure beer supplied from the beer introduction path 36. When pressed, the packing member 32 comes into close contact with the first valve seat 26, and shuts off the supply of beer from the beer introduction path 36 to the beer supply path 12. The foam passage 23 is provided in the cock body 10.
The valve 17 is closed. For this reason, the pouring nozzle 3
No supply of beer and no supply of foam to 8 is made.

As shown in FIG. 4B, the operation lever 1
When the valve body 4 is tilted forward to the beer discharging position, the valve body 15 moves backward in the beer supply path 12,
The first valve body 16 also moves backward against the supplied beer pressure. As a result, the packing member 32 is connected to the first valve seat 26.
The beer is introduced from the beer introduction path 36 to the discharge nozzle 38 in a communication state, and the beer supplied from the beer introduction path 36 is discharged from the discharge nozzle 38 to the mug via the beer supply path 12. The second valve body 21 disposed on the valve body 15 also moves backward, but does not sit on the second valve seat 33 at the beer discharging position.

Next, when the operation lever 14 is tilted from the beer dispensing position to the foam dispensing position further forward to perform the foam dispensing shown in FIG. 4C, the packing of the second valve body 21 is performed. The member 27 comes into close contact with the second valve seat 33, and the communication between the beer introduction path 36 and the discharge nozzle 38 is shut off.
At this time, the bubble passage 23 formed in the valve body 15 is formed.
Is opened to the discharge nozzle 38, and the beer supplied from the beer introduction path 36 to the foam passage 23 through the through hole 31 and the liquid passage 30 is textured when passing through the foam passage 23. It becomes fine foam and is later poured into the beer stored in the mug from the discharge nozzle 38.

Then, when the operator releases the operating lever 14 at the foam pouring position, the lever 14 automatically returns to the stop position by the beer pressure, and the beer introduction path 36 in the middle thereof.
The instantaneous release of the cutoff state between the beer supply path and the discharge nozzle 38 allows the bubbles remaining in the beer supply path 12 and the discharge nozzle 38 to completely flow out. That is, also in another embodiment, beer dispensing and foam dispensing can be performed only by tilting the operation lever 14 forward only,
Operation becomes simple. Moreover, since the foaming can be performed automatically, it is possible to always provide beer of a constant quality without requiring the skill of the operator.

In the embodiment and the other embodiments, the operation lever is always biased toward the stop position by the beer pressure (pressure of the sparkling beverage). However, the elasticity of the spring or rubber disposed in the cock body is used. A member or the like may be used as the urging means.

[0033]

As described above, according to the sparkling beverage dispensing cock according to the present invention, the sparkling beverage and the foam can be dispensed by tilting the operation lever in the same direction. Does not require an operation to temporarily return to the stop position, thereby simplifying the operation. In addition, since the foamed beverage can be supplied to the pouring nozzle and the foaming can be performed from the position where the foam is discharged to the position where the operation lever is returned to the stop position, the foamed beverage supply path can be performed without performing a complicated operation. And the foam remaining in the dispensing nozzle can be completely drained to provide a constant quality sparkling beverage.

In a device for automatically discharging an effervescent beverage and foam by automatically operating an operation lever, the control and mechanism relating to the operation of the lever can be simplified, and the cost can be reduced and the durability can be reduced. There are advantages that can be improved.
