Date Nov. 10, 1994An automatic shut-off valve for regulating the flow of beer or other liquid from its container, whereby a float is kept away from the outlet by directing some of the liquid upwardly against the float while most of the liquid is being discharged. The discharge of liquid is usually accompanied by a suction about the outlet which tends to suck the float downwardly to seal the outlet prematurely. By the present valve and the location of the float during discharge of liquid, premature sealing is minimized.</p> |
