ABSTRACT:
Valving apparatus designed for use in a remote-controlled beer-dispensing system. The apparatus includes a valve having a plunger selectively movable between opened and closed conditions, and a shiftable lever for controlling the position of the plunger. A pneumatic ram is coupled to the lever through a clevis. Upon supply of a pressurized gas to the ram, the clevis impacts the lever, shifting the latter to produce movement of the plunger from its closed to its opened condition. Upon exhaust of gas from the ram, a spring contained in the ram initiates return movement of the lever to produce movement of the plunger from its opened toward its closed condition, primarily under the influence of the spring. The upstream portion of the plunger has a surface which is exposed to and actable on by fluid flowing through the valve--this surface cooperating with the spring to complete movement of the plunger from its opened toward its closed condition. Such completing is primarily under the influence of fluid acting on this surface, whereby the plunger moves toward its closed condition substantially at the rate that fluid flows into and through the valve.
