  • Publication number: 20080007051
    Abstract: A female connector for releasable coupling with a male connector is disclosed herein. The male connector defines a fluid conduit and includes a male end adapted to be received within the female connector. The male end includes a coupling feature. The female connector comprises an opening, a collet finger, and an actuation element. The opening is adapted to guide the male connector along a first line of action as the male connector passes into the opening to be received within the female connector. The collet finger includes an engagement feature adapted to engage the coupling feature of the male end and displace along a second line of action generally normal to the first line of action. The actuation element is adapted to displace along a third line of action generally normal to the first and second lines of action in order to disengage the engagement feature from the coupling feature of the male end.

  • Publication number: 20070169825
    Abstract: The present invention is a fluid conduit coupling assembly for coupling a first fluid conduit to a second fluid conduit. The fluid conduit coupling assembly comprises a first coupler and a second coupler. The first coupler is for connecting to the first fluid conduit and comprises a first housing and a first valve. The first valve comprises a first lever arm. The second coupler is for connecting to the second fluid conduit and comprises a second housing and a second valve. The second valve comprises a second lever arm. When a force is applied to couple together the couplers, at least a portion of said force is communicated to each lever arm, thereby causing each valve to pivot from a closed position to an open position. The first valve and first lever arm are contained within the first housing, and the second valve and second lever arm are contained within the second housing.
