Patent number: 8523143Abstract: A detachable fluid coupling for connecting an inkjet printhead with an ink supply, the detachable coupling having a fixed valve member defining a valve seat, a sealing collar (146) for sealing engagement with the valve seat (148), a resilient sleeve (126) having one annular end fixed relative to the fixed valve member (128), and the other annular end engaging the sealing collar to bias it into sealing engagement with the valve seat. The coupling also having a conduit opening (150) that is movable relative to the fixed valve member for engaging the sealing collar (146) to unseal it from the valve seat. Unsealing the sealing collar from the valve seat compresses the resilient sleeve (126) such that an intermediate section of the sleeve displaces outwardly relative to the annular ends. With a resilient sleeve that buckles or folds outwardly, the diameter of the coupling is smaller that the conventional couplings that use an annular resilient element that biases the valve shut remaining residual tension.Type: GrantFiled: March 21, 2007Date of Patent: September 3, 2013Assignee: Zamtec LtdInventors: Brian Robert Brown, Norman Micheal Berry, Garry Raymond Jackson, Paul Timothy Sharp, John Douglas Peter Morgan, Kia Silverbrook, Akira Nakazawa, Michael John Hudson, Christopher Hibbard, Samuel George Mallinson, Paul Justin Reichl
