Abstract:
1. A valve assembly structured to reduce the delivery of air to a downstream location in a water supply line, said valve assembly comprising: a valve body disposed along and at least partially defining a path of fluid flow within the water supply line, said valve body including a sealing portion disposed in an exposed, interruptive and at least partially sealing relation to said path of fluid flow, at least one valve member movably disposed on said valve body between a sealing orientation and an open orientation relative to said sealing portion and in exposed relation to fluid passing along said path of fluid flow, said valve body further including a biasing assembly disposed and structured to exert a predetermined force on said at least one valve member, and said predetermined force being sufficient to dispose and maintain said at least one valve member into said sealing orientation relative to said sealing portion when said at least one valve member is subjected to a combined air pressure and water pressure existing within said path of fluid flow; said valve body including a plurality of valve members and a plurality of openings formed in said sealing portion, said plurality of openings extending through said sealing portion in communicating relation with said upstream and downstream sides of said sealing portion, said plurality of valve members movably disposed between said sealing orientation and said open orientation relative to a plurality of valve seats and in direct exposed, interruptive relation to said path of fluid flow; said valve body further including a retaining structure fixedly interconnecting said plurality of valve members and movable therewith at least between said sealed and open orientations; said biasing assembly being interconnected to said retaining structure in biasing relation concurrently to each of said plurality of valve members; and a stabilizing assembly connected to said sealing portion in movement restricting relation to said plurality of valve members; said stabilizing assembly disposed and structured to maintain a predetermined position of said plurality of valve members upon movement thereof between said sealed and open orientations.
