Abstract
A quick connect/disconnect coupling assembly (10) defining a fluid flow path is disclosed. The coupling assembly (10) includes a female coupling member (12) adapted for connection to a conduit (14) and a male coupling member (18) adapted for connection to a conduit or container (20). The female coupling member (12) includes a poppet valve assembly (90) which functions as an automatic shut-off when the female coupling member (12) is not interconnected to the male coupling member (18), the male coupling member (18) being adapted for removeable partial insertion into the female coupling member (12). The valve assembly (90) of the female coupling member (12) further includes a needle-like structure (92) for puncturing a penetrable membrane (28) at the front end of the male coupling member (18) upon insertion of the male coupling member (18) into the female coupling member (12) thereby enabling the flow of fluid therethrough.
