  • Patent number: 11612731
    Abstract: Quick disconnect fluid coupling devices described herein. The fluid couplings are configured for use in fluid systems for the purpose of providing a low-spill quick disconnect coupling. The fluid couplings include portions that are pivotable in relation to each other to open and close a fluid pathway through the fluid couplings. Particular embodiments of these fluid coupling can be configured to improve medical fluid handling equipment because the fluid coupling devices can be connected and disconnected (e.g., multiple times) while minimizing fluid spillage.

  • Patent number: 9732595
    Abstract: Embodiments usable within the scope of the present disclosure relate generally to a connector apparatus and methods usable to securely and repeatedly connect a sub-sea fluid conduit to another fluid conduit or well equipment, such as a manifold, a wellhead, a BOP, or other associated items. The disclosed embodiments further relate to systems and methods usable to remotely disconnect the fluid conduit and automatically shut off fluid flow therethrough. The male connector includes a flow control valve adapted to open upon connection with a female connector and to close upon disconnection from the female connector. The female connector is adapted to actuate the flow control valve of the male connector to the open position. The male connector includes a biasing member that actuates the flow control valve of the male connector to the closed position.

  • Patent number: 9347594
    Abstract: An hydraulic connection assembly for connecting one or more hydraulic lines may have a one-block body enclosing one or more hydraulic lines and at least one draining line connected to said hydraulic lines. The assembly may also have at least one coupling provided with an axially movable element adapted to actuate a sealing member to allow discharge of fluid pressure and relieve pressure from the tool lines before disconnecting or to facilitate maneuvering of connecting lines. The assembly also reduces the production costs and time, as well as the threes that the operator must apply when engaging pressurized lines.

  • Patent number: 9309739
    Abstract: Systems and methods enable connection of, and are usable to connect, well servicing equipment to other well equipment, including wellheads, blowout preventers, and other well servicing equipment. The systems comprise connecting apparatus having a male connector and female connector. The male connector comprises an elongate body having an axial bore extending therethrough and a plurality of protrusions extending from the elongate body at an angle relative to the axial bore. The female connector can be adapted for connection with the male connector, wherein engagement between the male connector and female connector communicates the axial bore of the male connector with a bore of the female connector to define a flowpath for communicating a medium. The systems and methods enable the ability to connect or disconnect well equipment remotely without the need of a diver, an ROV, and without the need to bring the well equipment to the surface for disassembly.

  • Publication number: 20090235997
    Abstract: A pump component is removed from a port of a suction-side fluid cavity of a high-pressure fluid pump. The pump component performs a pump function for the high-pressure fluid pump. A primary coupler connects to the port. The pump component connects to the primary coupler. A diverter fluid passage diverts a low-pressure fluid from the primary coupler to an auxiliary fluid delivery system. The primary coupler communicates the low-pressure fluid through the pump component and primary coupler to the port.

  • Patent number: 6499717
    Abstract: A method of use and apparatus for a quick connect coupling in a fluid system as disclosed herein. The quick connect coupling includes a female coupling assembly and a male coupling assembly. The female coupling assembly includes a female cone housing nestable with a female cone. At least one female flow hole is formed in each of the female cone housing and female cone. The male coupling assembly has a male cone housing nestable with a male cone. At least one male flow hole is formed in each of the male cone housing, and the male cone. The at least one female flow hole rotatably misaligns to seal in a manner that fluid is contained from leaking past the female coupling assembly. The at least one male flow hole rotatably misaligns to seal in a manner that fluid is contained from leaking past the male coupling assembly. The male coupling assembly is removably rotatably insertable into the female cone.

  • Patent number: 6340018
    Abstract: A control valve for a fuel injection valve, having a valve needle, which is displaceable in a control chamber that is provided with an inlet, an outlet, a valve needle seat, and a throttle seat. Various switching states that make different courses of the opening procedure of the nozzle needle, switched by the control valve, of the fuel injection valve possible. To that end, it is provided that a throttle ring is disposed on the valve needle and is provided with throttle bores, which extend parallel to the longitudinal axis of the valve needle, and that the dimensions of the throttle ring and valve needle are selected such that an outlet conduit is formed between the outer wall of the valve needle and the inner wall of the throttle ring.
