Abstract
A self-closing dispensing valve comprises a valve housing having a fluid conduit with a valve orifice therethrough, a flow control member within the valve body which is displaceable along an axis from a first position in which the flow control member obstructs the flow of fluid through the valve orifice to a second position in which the flow control member does not obstruct the flow of fluid through the valve orifice, and one or more resilient flexible fingers fixed to either the valve housing or the valve member which is deflected when the valve member is displaced to its open position. Preferably the fingers are arranged in pairs oriented parallel to the axis and are deflected toward the axis by a conical camming surface on the valve member when it is displaced from its closed position.
