  • (a) a housing having an inlet end and an outlet end and defining a valve bore between the inlet and outlet ends and a central channel downstream of the valve bore, the diameter of the central channel being greater than the diameter of the valve bore permitting air to accumulate within the central channel as fluid passes from the valve bore toward the outlet end;

    (b) a valve element contained within the housing and moveable between a closed position in which the valve element is substantially within the valve bore and an open position in which at least a portion of the valve element is outside the valve bore;

    (c) a spring contained within the housing and associated with the valve element for urging the valve element to the closed position; and

    (d) an air exhaust port associated with the housing downstream of the valve bore, the air exhaust port defines an air passageway in fluid flow communication with the central channel to exhaust said accumulated air from the central channel.
