  • Patent number: 9695968
    Abstract: An apparatus for an improved cam lock fitting having cooperating double cam levers having outer and inner portions so that when the outer cam levers are opened and the inner cam lever remain closed, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. This is accomplished by providing a larger cam lobe on the outer cam lever and a smaller cam lobe on a fork shaped inner cam lever so that when the smaller cam lobe is in a closed position and protrudes into a peripheral groove on the male portion the male and female ends have a small space thereinbetween.

  • Patent number: 8888143
    Abstract: Fluidic coupling assemblies include a fitting body having a single integral piece or separable pieces such as male and female fittings such as luer fittings. The assemblies further comprise a rotatable fastening assembly having a drive collar and a driven member, and at least one resilient member having a spring bias that defines a threshold torque of the rotatable fastening assembly. The spring bias may be directed axially or radially with respect to the longitudinal axis of the fluidic coupling assembly. The resilient member is configured to prevent overtightening of the fluidic coupling assembly by allowing the drive collar to rotate the driven member only when less than a threshold torque is applied. Rotation of the rotatable fastening assembly imparts a compressive force on the resilient member, and the resilient member yields when the compressive force exceeds the spring bias of the resilient member.

    Abstract: A compression fitting or joiner for joining pipe ends having a plurality of tiltable annuli (17, 18) removably receivable over the pipe ends (6,8) and a fluid sealing housing (11). The fluid sealing housing (11) encloses the annuli (17,18). The annuli (17,18) are restrained from longitudinal movement on one side by means of a tab (5) inserted in an aperture (7) located in the housing (11). When a pull-out force is applied to the pipe end (6 or 8), the housing (11) retrains each annulus (17,18) on one side, causing each annulus to tilt from a position substantially perpendicular to the housing. This tilt reduces the effective lateral cross-sectional area inside each annulus (17,18) resulting in the application of a compressive force to the associated pipe end (6) thereby holding the pipe end (6) within the housing. To subsequently remove the pipe end (6) from the housing (11) a force is applied to remove the tilt from the annuli (17, 18).

Alternatively, the preload feature can be incorporated into the dog or other locking assembly that holds the components of the connection together. The connection is particularly useful in subsea chokes which have a removable insert which can be mounted to or removed from the choke body which is located subsea.

  • Patent number: 6142537
    Abstract: The connector includes a male member with an engaging portion on its outer face, a female member with an inner space for receiving the male member and a pair of manipulating members provided in the female member from opposite sides. The engaging portion of the male member is received through and behind the pair of manipulating members in the inner space. Each manipulating member has a part which enters the track region of the engaging portion and an elastic piece. The coupling of the male and female members is reliably obtained by two opposite side engagements between the engaging portion of the male member and the pair of manipulating members and maintained by the thrusting force by the elastic piece.

  • Patent number: 6086119
    Abstract: A detachable, quick connect connector having a retaining spring with jaws for engaging a locking ring of a tube. The connector includes a housing with a chamber for receiving the tube and the retaining spring. The retaining spring has a pair of inwardly directed jaws which are opened by pushing a plate connected by webs to the jaws. When opened, the jaws permit the locking ring to pass through and close to engage the ring when the tube has been fully inserted. A support member projects outwardly from each jaw and is received in a recess formed in the housing wall. The support members have arcuate surfaces to engage a contact surface along the recess to secure the retaining spring axially in the housing. The end faces are beveled outwardly from a radial plane by an angle between 15.degree. and 60.degree. to increase the retaining force of the support members.

  • Patent number: 6059324
    Abstract: A coupling element connects a connection piece with an insertable end of a connection tube having a toroidal flange for contacting the connection piece in the tube inserting direction. A plug-in fork can be inserted into the coupling element to releasably secure the inserted tube end area against the tube inserting direction, with the tube torus held in place by the plug-in fork. For this purpose, pairs of plug-through openings are provided on side walls of the connection piece opposite one another, so that one prong of the plug-in fork can be inserted into each opening. Inserting bevels are assigned to at least a portion of the plug-through openings, which inserting bevels are shaped such that they cause a forced movement of the plug in fork in the tube inserting direction during its insertion in the plug-in fork inserting direction.

  • Patent number: 5816623
    Abstract: A self-locking quick-disconnect coupling device includes a female coupler including a stop formed thereon and an opening defined therethrough. A male adaptor through which a recess is defined is insertable into the female coupler. A cam handle includes a handle portion and a cam portion rotatably mounted on the coupler between a releasing and an engaging position so that the cam portion is moved through the hole into the recess. A hooking element is pivotably linked to the handle portion. The hooking element includes a barb projecting therefrom and including an inclined surface. A locking control element including first and second distal ends is pivotably linked to the handle portion. The inclined surface will slide on the stop when the cam portion is pivoted from the releasing position to the engaging position thus allowing the barb to snap into engagement with the stop when the cam handle is in the engaging position.
