ABSTRACT:
A dry break coupling for joining together opposing passageways includes a male member and a female member, each of which includes a resiliently deformable rubber flap with cross-hair slits positioned to engage each other as the male and female members are moved axially toward their coupled position. Each of the male and female members also is provided with a normally closed but resiliently openable rubber septum position on the opposite side of its rubber flap from the engagement end of the respective members. The male member is provided with a blunt cannula which is fixed and a moveable carrier supporting the rubber septum. The female member is provided with an axially moveable support for the rubber flap and a fixed support for the rubber septum. As the male member and the female member move to the fully coupled position, the peripheral portions of the abutting rubber flaps are moved axially with the female carrier member while the central portions are prevented from moving by the fixed septum support with the result that the slits of the rubber flaps are pulled open thereby permitting the respective septums to engage each other. Further movement of the male and female members toward one another causes the moveable support for the male member septum to be retracted with the result that the cannula is urged through the resiliently openable abutting septums to open the passageway to the flow of fluid.
