Patent ID: 7510216

Claim:
Quick disconnect apparatus comprising: a first tube formed with a first extremity and including a peripheral bead adjacent the first extremity; a second tube formed with a second extremity for positioning in a coupling position relative to the first extremity; a compressible tubular seal device including a mounting cuff mounted on the second extremity and bonded thereto, the seal device including a cylindrical wall defining a cowling projecting beyond the second extremity to, when the first and second tubes are in the coupling position, project concentrically over the bead, the cowling further formed at its free extremity with an internal sealing ring configured to engage the first tube behind the bead and cooperating with the wall to, when so engaged, define a predetermined outside diameter at the free extremity of the cowling; and a tubular slider shell concentric with the seal device and shiftable axially there along from an uncoupling position retracted onto the second tube to a coupling position and including a mounting sleeve slidable on the seal device and a constraining collar projecting from the sleeve and shiftable, when the slider shell is slid to the coupling position, to align with the free extremity of the cowling and being further formed with an internal diameter smaller than the predetermined diameter to, when so aligned, compress the sealing ring radially inwardly into sealing engagement against the first tube.
