Abstract

A pressure locking dispenser half which securely locks with a receptacle half which comprises a connector, a barrel sleeve, and a moveable adaptor. The connector includes first and second passageways. The first passageway of the connector further includes a first port and the second passageway includes a second port, a first seal and a second seal residing between the connector and the adaptor. The adaptor engages the barrel sleeve. The barrel and adaptor include a vent passageway. A spacer resides between the first and second seals maintaining separation of the first and second seals. The moveable adaptor positions the first and second seals in one of a plurality of positions with respect to the connector. A dispenser valve 12 acts in combination with a retainer, a sliding sleeve, and a locking sleeve to pressure lock the dispenser half and the receptacle half together under certain circumstances. Certain positions of the adaptor allow the venting of the dispenser half and the receptacle half.
