  • Patent number: 10247340
    Abstract: A locking quick connect assembly is provided for removably coupling a first tube and a second tube. A quick connect housing presents a central bore for receiving the second tube. A redundant latch component positionable between an unlocked position and a locked position may be provided to slidingly engage the quick connect housing. A twist lock retainer surrounds the quick connect housing and the redundant latch component. The redundant latch component includes an axially extending peg and the twist lock retainer includes a locking channel for receiving the peg. The twist lock retainer also includes a twist lock arm that locks against a bead of the second tube to resist separation. The twist lock arm extends perpendicularly to and radially inwardly of the locking channel to interleavingly engage the peg thus preventing unwanted decoupling of the assembly.

    Abstract: A plug-in connection system for fluidic lines, fittings or assemblies, having a housing part and a plug part that can be plugged into a receiving opening of the housing part. A holding element on one of the coupling parts latches with a mating holding element on the other of the coupling parts. The holding element has a spreading surface that, by sliding relative to a corresponding surface of the plug part causes a spreading movement of the holding element, transversely with respect to an axis during installation. In order to improve the plug-in behavior during installation, a spreading contour of the spreading surface engages a mating contour in such a way that, while being plugged in, the spreading travel (Sw) of the holding element changes in a non-linear manner, depending on the status of installation.

  • Patent number: 7938456
    Abstract: A quick connect and quick release coupling for connecting two pipes, including a male element and a female element that are axially fitted and interlocked one inside the other and wherein a locking mechanism retains the male element in a coupled position and a temporarily retaining mechanism immobilizes the male element, after its release by the locking mechanism, in a position for flushing a pipe connected to the male element. The locking mechanism is controlled by a sleeve that slides relative to a body of the female element. When the temporarily retaining mechanism retains the male element in flushing position, it is subjected to a first force (E1) derived from a pressure (P) of the fluid flowing (F) from the male element outwards and to a second force (E2), opposite to the first, exerted by elastic return means which, when the pressure (P) drops to a safety threshold, moves the temporarily retaining mechanism into a position for releasing the male element from the female element.

  • Patent number: 7770940
    Abstract: A coupling part for a plug connector arrangement is provided. The coupling part having a coupling body comprising a receptacle into which a plug-in part can be plugged into in the direction of a longitudinal axis of the receptacle, in order to produce a fluid-tight connection. The coupling part has two spaced-apart locking elements which, in a locking position, penetrate laterally, opposite one another, into the receptacle in order to engage behind the plug-in part and which can be moved into a release position in order to release the plug-in part. A spring element is integrally formed with and connects the locking elements together. In order to develop the coupling part so that it is easier to handle, the coupling part is provided with an actuating element which is adapted to be moved relative to the coupling body.

  • Patent number: 7708320
    Abstract: A plug-in part for a plug connector arrangement is provided. The plug-in part being in the form of a piece of tubing and having a sealing portion, comprising a sealing element enclosing the piece of tubing in a circumferential direction, and a locking portion with at least one undercut, and it being possible for the plug-in part to be plugged into the receptacle of a coupling part of the plug connector arrangement in order to produce a fluid-tight connection, and for at least one locking element of the coupling part to engage behind the plug-in part in the region of the undercut. In order to develop the plug-in part so as to reduce the risk of the sealing element being adversely affected, the undercut is formed by a protrusion which projects from the outside of the piece of tubing and extends circumferentially merely over a sub-region of the piece of tubing.

  • Patent number: 7568737
    Abstract: A male coupling is connectable to and separable from a female threaded coupling. The female threaded coupling includes a sealing surface and a receiving portion sized to receive at least a portion of the male coupling, where the receiving portion has internal threads provided therein. The male coupling includes a body having a passageway extending therethrough and a locking member disposed about the body and configured to move between locking and releasing positions. The locking member has a retaining formation configured to engage the internal threads of the female threaded coupling when the locking member is in its locking position. After insertion of the male coupling into the female threaded coupling, the retaining formation of the locking member engages one or more of the internal threads in the female threaded coupling when the locking member is in its locking position.

  • Patent number: 7452006
    Abstract: A pipe coupling is disclosed which comprises a plug (14) and a socket (12). When the plug is inserted into the socket, the plug first urges sleeve actuators (28) radially outward to axially move a sleeve (22) and, thereafter, urges locking elements (20) radially outward to move the sleeve further. Eventually, the locking elements and sleeve actuators are fitted within a locking recess (14-2) of the plug to securely connect the plug and the socket.

  • Patent number: 7431346
    Abstract: A socket of a fluid coupling device includes a housing with a cavity centered on an axis. A pawl, attached to the housing, is pivotable about a pivot location relative to the housing, and has a catch section located axially outward from the pivot location. A spring biases the catch section radially inward. A plug is configured to move axially into the cavity while sliding against the catch section to move the catch section radially outward, against bias of the spring, out of the way of the plug. After an axially-outwardly facing catch surface of the plug passes the catch section, the catch section can pivot radially inward and abut the plug catch surface to capture the plug in the socket.
