Abstract:
A dispensing system for dispensing liquid from a container, said system comprising:a discharge conduit defining a flow passage for establishing fluid communication with said liquid from said container;a resilient valve that extends across said discharge conduit flow passage, has an interior side for being contacted by said liquid and an exterior side exposed to the ambient external atmosphere, and defines a dispensing orifice that opens when the pressure on said valve interior side exceeds the pressure on said valve exterior side by a predetermined amount; anda resilient baffle located upstream of said valve, said baffle including an occlusion member supported by at least one resilient support member which accommodates movement of said occlusion member between a closed position occluding flow into at least a portion of said conduit flow passage when said baffle is subjected to an upstream hydraulic hammer pressure, and biases said occlusion member to an open position permitting flow into said conduit flow passage adjacent said valve when said baffle is not subjected to said hydraulic hammer pressure.
