The spring member 50 interposed between the opening side end face and the bottom plate of the sleeve 42 is urged to contact the seal member 47 fitted in the slider 41, and the narrow through hole 46 a is always closed by the seal member 47. It has come to be. Further, the narrow through hole 46a of the foam dispensing valve body 46 is set to have a sufficiently small inner diameter in the form of an orifice, and beer is ejected vigorously and collides with the opposing seal member 47 to produce fine foam. It is like that.

  The beer dispensing operation of the sparkling beverage dispensing cock 10 configured as described above will be described. In the sparkling beverage dispensing cock 10, as shown in FIG. 1, when the lever 30 is in the neutral position before operation, the fluid dispensing valve body 45 is biased by the spring member 49 to the fluid dispensing valve seat 22. The beer supply from the beverage supply path 11 to the inner hole 21 is blocked and the foam pouring valve body 46 is urged by the spring member 50 to the foam pouring valve seat 47 and sits down to foam. The thin through hole 46a of the delivery valve body 46 is closed. Therefore, liquid beer and foam beer are not poured out from the liquid pouring nozzle 23 and the foam pouring nozzle 24.

  In this state, when the lever 30 is tilted to the left as shown in FIG. 1, the slider 41 moves through the inner hole 21 in the right direction as shown in FIG. When the slider 41 moves in the right direction in the figure, the liquid extraction valve body 43 urged toward the slider 41 via the bubble extraction valve body 46 resists the elasticity of the spring member 49 in the right direction in the figure. The beer sent from the beverage supply pipe 11 passes through the inner hole 21 and is poured into a beverage container (not shown) via the liquid dispensing nozzle 23. . At this time, since the bubble extraction valve element 46 is urged to the left in the figure by the spring member 50, the thin through hole 46a remains closed without being separated from the bubble extraction valve seat 47. Foamed beer is not supplied to the outlet nozzle 24.

  At this time, since the sleeve 21 is moved rightward in the drawing due to the inclination of the lever 30, the communication between the annular groove 42 c and the air hole 28 is cut off, and the air is not introduced into the liquid dispensing nozzle 23. Excessive foaming due to mixing is prevented.

  Next, when the lever 30 is tilted to the right side shown in FIG. 1, as shown in FIG. 3, the slider 41 moves in the left direction shown in FIG. When the slider 41 moves in the left direction in the figure, the sleeve 42 connected to the slider also moves in the left direction in the figure, and the foam discharge is biased toward the bubble extraction valve seat 47 by the spring member 50 in the sleeve 42. The valve body 46 also tries to move in the left direction in the figure. However, the bubble extraction valve element 46 is connected to the liquid extraction valve element 43, and the liquid extraction valve element 43 abuts the liquid extraction valve seat 22 in the left direction in the drawing together with the slider 41. Since it does not move, the bubble extraction valve element 46 is separated from the bubble extraction valve seat 47 provided on the slider 41, and a thin through hole formed in the bubble extraction valve element 46. 46a is opened.

  For this reason, beer from the beverage supply path 11 is ejected from the thin through hole 46a of the foam dispensing valve body 46 through the through hole 43a penetrating the liquid dispensing valve body 43. The narrow through hole 46a is set to have a sufficiently small inner diameter in the form of an orifice, resulting in fine foam. The foamed beer passes through the opening 42b formed in the sleeve 42, and the annular groove formed in the inner hole 21. It flows through the nozzle 25 for foam extraction 24 and flows out from the nozzle 24 for foam extraction into a beverage container (not shown).

  At this time, since the sleeve 42 is moved in the left direction in the figure due to the inclination of the lever 30, external air is introduced into the liquid injection nozzle 23 without blocking the communication between the annular groove 42c of the sleeve 42 and the air hole 28.

The sparkling beverage pouring cock 10 configured as described above has the annular groove 25 formed in a range narrower than the inlet portion of the foam pouring hole of the foam pouring nozzle 24 in the axial direction of the inner hole 21 . The beer does not accumulate in the annular groove 25 and remains, and the foamed beer is prevented from dripping from the foam dispensing nozzle 24 later. Similarly, since the opening 42b formed in the sleeve 42 is formed in a range narrower than the annular groove 25 in the axial direction of the inner hole 21, the beer in the foam state is less likely to accumulate in the opening 42b and the annular groove 25 of the sleeve 42. The beer in the foamed state is prevented from dripping from the dispensing nozzle 24 later. Further, an opening 42b bored in the sleeve 42, even when any of when stopped pouring beer foam state and the lever when to dispense beer foam state is returned to the neutral position, the bore 21 Since it is within the range of the annular groove 25 in the axial direction, the foamed beer flows quickly when the foamed beer is poured out, and the foamed beer accumulates in the opening 42b and the annular groove 25 when the dispensing is stopped. The beer in the foamed state is not left behind from the foam dispensing nozzle 24 without remaining.

It is a sectional side view of the sparkling beverage dispensing cock according to the present invention. It is a principal part sectional side view in the neutral state of the lever of the sparkling beverage pouring cock concerning the present invention. It is the principal part side sectional view which tilted the lever of the sparkling beverage pouring cock concerning the present invention, and made it the foam pouring position of a foam state.
