At this time, the valve slider 100 (for example, the first valve body 110, the second valve body 130, and the closing member 160), except for the third valve body 140, (110) is in close contact with the valve seat (11a) side of the valve body (10).

In this state, the third valve body 140 moves backward in the inner space 138 of the second valve body 130 while pressing the elastic body 34 by the backward movement of the mounting portion 41. As the third valve body 140 is retracted, the end 122a of the second foam generation passage 122, which was closed by the sealing member 142 of the third valve body 140, is opened.

In this state, the beer passes through the first foam generating passage (114) of the first valve body (110) and the second foam generating passage (122) of the valve stem (120) 2 flow out into the inner space 138 of the second valve body 130 through the end portion 122a of the bubble generating flow path 122 to be filled in the inner space 138. [ The foam filled in the inner space 138 of the second valve body 130 flows out through the minute gap between the second valve body 130 and the third valve body 140, And is drawn out to the beer cup through the foam draw-out port 22 and the foam draw-out flow path 27 of the draw-out nozzle 25. [

As described above, the valve slider according to the present invention is advantageous in that it is simple to assemble and disassemble, and is easy to operate. Further, after the beer and the foam are withdrawn, the beer or foam is effectively blocked from moving through the valve slider and the flow path, and the beer or foam is prevented from being transferred to the valve body through the gap between the closing member and the flow path of the valve body. There is an advantage that leakage to the outside from outside can be effectively prevented.
