  • Continuous choke for downhole valve
    Patent number: 12359535
    Abstract: A continuous choke for a flow control valve is provided. The continuous choke can be included in a fully electric, full bore flow control valve. The continuous choke comprises a housing comprising at least one opening, a sleeve comprising at least one opening aligned with the at least one opening of the housing, a piston slidable relative to the sleeve to progressively cover or uncover the at least one opening of the sleeve to progressively decrease or increase, respectively, flow through the continuous choke, wherein the piston is configured to slide distally relative to the sleeve to move toward a closed position, the piston comprising a plurality of channels configured to direct fluid flow.
    Type: Grant

  • Bi-directional pressure energized axial seal and a swivel connection application
    Patent number: 9243711
    Abstract: A tubular connection has first and second tubular members having aligned bores with a common axis and having first and second seal surfaces, respectively. A metal seal has a first end portion that sealingly engages the first seal surface and a second end portion that sealingly engages the second seal surface. The metal seal has a sidewall with at least two folds. One of the folds defines an axial interior gap. The other of the folds defines an axial exterior gap. An exterior spacer member is positioned in the exterior gap to limit closer of the exterior gap in response to a greater pressure on the interior of the seal than on the exterior. An interior spacer member is positioned in the interior gap to limit closure of the interior gap in response to a greater pressure on the exterior of the seal than on the interior.
