  • Patent number: 8616586
    Abstract: A sealing element that includes a hollow body of metallic material and first and second male sealing members formed at a respective end of the body. The respective male sealing member has an external spherical contact surface designed for mating with a corresponding internal conical contact surface of a female sealing member so as to form a fluid-tight seal between the male sealing member and the female sealing member when their contact surfaces are pressed against each other. Also, a coupling device and a valve device provided with the sealing element.

  • Patent number: 7913716
    Abstract: A sealing element including a tube-shaped body of metallic material and first and second male sealing members arranged at a respective end of the body. At least two intermediate members are arranged in series in the body between the first and second male sealing members. Each one of the intermediate members is compressible so as to be capable to store elastic energy when the body is subjected to axial compression and includes a protuberance arranged in the body and extending around the center axis of the body. A coupling device provided with such a sealing element.

  • Patent number: 7520989
    Abstract: A subsea separation apparatus for processing crude oil, which includes a separator module with a separator tank. The separator tank defines an opening going there through. The opening is located substantially at the geometrical center of the separator tank, and may be used for other processing equipment for the crude oil. The separator tank may be substantially symmetrically placed on a well head, and the separator module may be substantially concentrically placed on the well head.

  • Patent number: 7326865
    Abstract: An electrical switching device including at least one ingoing conductor at least a first and a second outgoing conductor, and an arrangement for connecting and disconnecting the conductors by means of an axial movement. The arrangement includes an axially movable element, which is movable between a first and a second position. The device is arranged such that when the axially movable element is in the first position, the ingoing conductor and the first outgoing conductor are electrically connected, and the ingoing conductor and the second outgoing conductor are disconnected. When the axially movable element is in the second position, the ingoing conductor and the first outgoing conductor are disconnected, and the ingoing conductor and the second outgoing conductor are electrically connected.

  • Patent number: 7143994
    Abstract: The invention relates to a coupling device including a coupling part provided with a coupling member and having an internal bore extending through the coupling part and its coupling member, wherein the coupling part is provided with a valve, which includes a valve body displaceably arranged inside the internal bore and a spring member acting on the valve body, the valve body being displaceable against the action of the spring member from a first position to a second position. The valve includes a housing fixed inside the internal bore, the housing being provided with a cavity accommodating the spring member and a part of the valve body. The cavity is in fluid communication with an orifice at the end of the valve facing the free end of the coupling member so as to allow the cavity to be in fluid communication with the surroundings via the orifice when the coupling member is out of engagement with a corresponding coupling member.
