Abstract: A fluid coupling has a first part (100) sealed to a sealing surface of a second part (200), wherein the first part carries a sealing part (300) and the second part includes a gap (G) in the sealing surface, across which the sealing part is arranged to transition. A vent (210) is provided between the sealing surface and the gap. An aperture to the vent on the sealing surface is relatively small so that fluid pressure does not act to deform the seal as it crosses said aperture. Said aperture is spaced off-set from the gap on the sealing surface. The off-set provides a portion of sealing surface adjacent the gap and between the gap and aperture against which the seal can contact. The vent acts to allow fluid (400) to enter the gap before the seal starts to cross the gap and to therefore act to equalise pressure on either side of the seal.

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.

Abstract: An improved quick-disconnect connector assembly for connecting hoses, having a female element for connection to a first hose and a male element for connection to a second hose. The female element has an axial bore having a sealing mechanism for sealably receiving a tubular portion of the male element. The male element further comprises resettable valve including a coil spring that extends into the bore in the female element and is retained therein by a U-shaped clip. The spring is sized to hold the male element axially within the sealing mechanism up to a desired inline pressure. When the pressure limit is exceeded, the male element spring is extended until the seal is broken, relieving the overpressure condition. When the un-sealing force has been relieved, the extended spring biases the male element back into sealing relationship with the female element, thereby automatically resetting the relief valve.

Abstract: A releasable connector connects between coiled tubing, a pipe string or similar tubular string and a tool/piece of equipment. Two sleeve-shaped inter-connectable parts are configured to be releasable, wherein one is connected to the coiled tubing, and the other is connected to the tool/equipment. A locking device holds the two sleeve-shaped parts of the connector in a blocked non-released position, and a retaining sleeve keeps the locking device in its locking position. The retaining sleeve is axially displaceable for releasing the connector by a sufficient, axial displacing movement. A coaxial displaceable piston body with a transversal end surface can be influenced by fluid pressure in order to start a releasing process. The piston body has a spring, which resists the displacement of the piston and is arranged in a spring chamber. In an initial position of the connector, the spring chamber is filled with a medium which can be forced out through a cavity and an opening.

The apparatus includes a first liquid containing component having at least one liquid passage, a second liquid containing component including at least one liquid passage, a movable connecting member having portions contained in the passages of the first and second liquid containing components, and a force transmitting member connected with the movable connecting member. The force transmitting member directs force against the first liquid containing component when the liquid passages of the first and second liquid containing components contain the pressurized liquid. This securely connects the first and second liquid containing components together using force generated by the internal pressurized liquid. When the pressure is removed, the force transmitting member may be quickly removed to disconnect the components.

Abstract: A coiled tubing drilling hydraulic disconnect for use in disconnecting a tool from a length of tubing or other tool string. The apparatus has an upper housing and a lower housing with a splined ring threadingly engaged with the lower housing. A spline in the splined ring engages a spline on the upper housing so that torque may be transmitted therebetween. Lugs are disposed through windows in the lower housing below the splines, and a bushing is disposed between the splined ring and the lugs. Relative rotation between the upper and lower housings causes the splined ring to tighten against the bushing and lugs, thereby eliminating play therebetween. A lug prop disposed in the upper housing may be hydraulically actuated so that the lugs may move to a disconnect position, thereby releasing the upper housing from the lower housing. Because the windows are disposed below the splines, no torque or bending are applied to the windows, and the windows and lugs are shaped to minimize stress concentrations.

Abstract: A tension actuated fuel (e.g. gasoline) delivery hose uncoupler is disclosed in which, upon a predetermined tension load being applied to the delivery pump hose, the coupling will automatically uncouple thus releasing one end of the hose which, for example, may remain inserted in the fuel tank of a vehicle driving away from the fuel dispensing pump, and the other portion of the hose which is permanently affixed to the pump. The coupler includes normally closed check valves which, upon uncoupling of the coupler, close thereby preventing spillage of fuel. Further, the coupler is adjustable so that it may be calibrated to uncouple at predetermined tension loads. The uncoupler is structured so as to substantially eliminate the effects of fluid (e.g., gasoline) delivery pressure on the tension load required for uncoupling.
