Abstract

A normally closed valve that may be opened upon insertion of a nozzle, wherein an actuator that engages the nozzle is shaped to enhance the ability to flush thoroughly the interior volume of the valve, which includes a valving chamber. Located in the valving chamber is an actuateable valve element that, in a first position, blocks flow through the passageway passing through the housing and that, in a second position, permits flow through the passageway. The actuator, which has a perimeter wall, is disposed adjacent the actuateable valve element. The inlet end of the actuator engages the nozzle when the nozzle is inserted into the valve, and the actuator urges the actuateable valve element into the second position when the nozzle pushes on the actuator. The perimeter wall may define an interior actuator path passing through the inside of the actuator. An exterior actuator path passes between the perimeter wall and the housing. The actuator includes structures for permitting flow from the nozzle to the exterior actuator path, and in a preferred embodiment, structures disposed on the perimeter wall's outlet end permit flow from the interior actuator path to the valving chamber. The ac…
