Abstract
A valve including a substantially rigid cannula and a valve member connected for operable communication with the cannula. The valve member is formed from a substantially resilient material and is movable with respect to the cannula between a first closed position and a second open position. The cannula cooperates to extend through the valve member during movement from the first closed position to the second open position to establish a fluid flow path through the cannula and the valve member. A sealing member is also provided which operates independent from a flow of fluid within the fluid flow path and independent from any component utilized with the valve to automatically provide positive sealing of an opening within the valve member when the valve member is positioned in the first closed position, the cannula extending through the opening during movement of the valve member.
