Abstract
A dispensing system is provided for dispensing liquid from a container. The system includes a discharge conduit defining a flow passage for establishing fluid communication with liquid from the container. A resilient valve is provided to extend across the discharge flow passage. The valve has an interior side for being contacted by the liquid and an exterior side exposed to ambient external atmosphere. The valve defines a dispensing orifice that opens when pressure on the valve interior side exceeds the pressure on the exterior side by a predetermined amount. A resilient baffle is located upstream of the valve. The baffle includes an occlusion member supported by at least one resilient support member which (1) accommodates movement of the occlusion member between a closed position occluding flow into at least a portion of the conduit flow passage when the baffle is subjected to an upstream hydraulic hammer pressure, and (2) biases the occlusion member to an open position permitting flow into the conduit flow passage adjacent the valve when the baffle is not subjected to a hydraulic hammer pressure.
