  • Patent number: 8882158
    Abstract: A connection system for carrying a refrigerant may provide a hybrid redundancy in sealing a refrigerant flow from the surround system environment. The connection system may include a first sealing ring of a first type and a second sealing ring of a second type positioned downstream from the first sealing ring. In some embodiments, the first sealing ring may be in a groove positioned around the outside diameter of a male fitting. The second sealing ring may be positioned at an interface between the male fitting and a female fitting. In some embodiments, flanges of each fitting define the interface so that the second sealing ring may be positioned between the flanges of each fitting. The second sealing ring may be selected from a material that has a wider range of operating temperature than the first sealing ring so that in the event of failure in the first sealing ring, the second sealing ring may prevent leakage.

  • Patent number: 7837646
    Abstract: A shunt system quick connector assembly to quickly connect and disconnect a catheter to a hydrocephalus shunt system comprising a valve in a valve housing. The catheter is affixed to the quick connector assembly. The quick connector assembly snaps over an external barb on the valve housing of the shunt system with an audible sound, so that the surgeon knows that connection has been made. The connector assembly can be operated quickly, minimizing the time for the surgical procedure and the opportunity for infection. The connector assembly has smooth surfaces to minimize the growing of tissue into the connection.

  • Patent number: 7815224
    Abstract: A rotating union communicates with a rotor member and is operable with either compressible or incompressible coolant media that enters the union through a media inlet. The union includes a housing having a counterbore and a tubular carrier member axially moveable in the housing. The union includes a primary seal assembly having a rotating seal member mounted to the rotor member and a non-rotating member mounted to the carrier member and a secondary seal member positioned about the carrier member. The range of the balance ratio of the primary seal assembly is disclosed when the primary seal assembly has imposed upon it a closing force, an opening force or no force.

  • Patent number: 7758086
    Abstract: A fluid connection assembly (10) includes a metal tube (22) having a flared end and a plastic manifold (12) having a port (14). The port (14) includes an annular collar (16) and an annular recess (18) that receives a seal (20). The metal tube (22) is arranged over the port (14) and engages the seal (20). The flared end of the metal tube (22) abuts the annular collar (16) of the port (14) when the metal tube (22) is installed. A plastic retainer (28) is molded over the annular collar (16) of the port (14) and the flared end of the metal tube (22) to retain the metal tube (22) axially on the port (14) of the manifold (12).

  • Patent number: 7740248
    Abstract: A seal assembly capable of low temperature service is disclosed. It features upper and lower metallic backup rings that are specially shaped to act as a spring to keep the sidewalls of such rings in contact with the inside and outside surfaces to be sealed to prevent extrusion of the seal material even in low temperature situations. Inner and outer grooves are provided. O-ring seals, used for the ID of the seal, are manufactured to have a slightly greater diameter than the groove into which they will be installed. The greater length provides stored energy to promote sealing functionality in cold temperature situations. The O-rings used for the OD of the seal are manufactured to have a slightly smaller diameter than the groove into which they will be installed. The shorter length provides stored energy to promote sealing functionality in cold temperature situations.

  • Publication number: 20100084859
    Abstract: A subsea coupling comprises a male coupler having a probe and a female coupler comprising a socket for the reception of the probe. The couplers each include a valve which is openable on mating of the couplers to provide communication with the socket. The socket includes a recess accommodating an annular seal for providing a radial seal between the probe and the socket. In one embodiment the leading edge of the probe includes at least one relief channel for allowing the escape of hydraulic fluid entrapped between the probe, the seal and the recess when the couplers are made up. There may be a stand-off ring disposed between one end of the recess and the inner side of the seal. In another embodiment the relief channel is provided in the socket.
