摘要： Rotary steerable drilling systems are subjected to harsh environments including high temperature and pressure. A metallic seal ring prevents or limits erosive wear by limiting the velocity of the fluid that traversers from the high pressure side of the metallic seal ring to the low pressure side of the metallic seal ring to a value that can be sustained by the material of the metallic seal ring. A metallic seal ring is capable of withstand the wear and tear of drilling mud or other fluids used for downhole drilling operations. A metallic seal ring includes a mating configuration that creates a seal as the metallic seal ring is contracted when or a tension is applied when disposed or positioned in the piston bore. The metallic seal ring maintains an adequate seal to protect the components of a pad assembly over the life or specified duration of a downhole drilling operation.

摘要： A system is disclosed as including a seal for sealing an area between a hanger and a housing of a wellhead. The seal is provided with at least a notch that defines at least a movable portion such as a wing or a lip. An e-ring is provided for a first energizing of the seal. The movable portion enables pressurized fluid from beneath the seal to cause the movable portion to protrude further against a mating side in the wellhead and the hanger for a second energizing of the seal. This type of seal maintains or improves the sealing of the wellhead in high pressure applications. Methods applied to the above seal are also disclosed.

摘要： In a sealing device, a crank-shaped oil channel is defined in an abutment of a sealing ring for sealing between a shaft member and a housing which surrounds the shaft member and is rotatable relative the shaft member. The crank-shaped oil channel is comprised of a first oil channel portion and a second oil channel portion which extend axially, and a third oil channel portion which connects the first and second oil channel portions to each other. If the sealing ring is thermally expanded circumferentially due to a change in temperature, the sectional area of the flow path in each of the first and second oil channel portions is varied, but the sectional area of the flow path in the third oil channel portion is not substantially varied. Therefore, it is possible to leak a given amount of an oil from one side of the sealing ring through the crank-shaped oil channel to the other side, thereby preventing the wearing of the shaft member caused by foreign matter, such as an iron powder, contained in the oil.
摘要翻译：在密封装置中，曲轴形的油通道被限定在用于在轴构件和围绕轴构件的壳体之间进行密封并且可相对于轴构件旋转的密封环的邻接处。曲柄形油路由第一油路部和轴向延伸的第二油路部以及将第一和第二油路部彼此连接的第三油路部构成。如果密封环由于温度变化而周向热膨胀，则第一和第二油道部分中的每一个中的流路的截面面积是变化的，但是第三油路部分中的流路的截面面积是没有实质的变化。因此，可以将密封环的一侧的给定量的油从曲轴形油路泄漏到另一侧，从而防止由铁粉等异物引起的轴构件的磨损，含在油中。

摘要： A metal stem seal for sealing between a movable stem and a stem opening in a valve body has an annular seal body through which the stem extends. The seal has a flexible annular seal leg depending from the seal body for sealing against the stem. The inner surface of the seal leg has at least one groove defining a plurality of sealing lands, including at least a lower sealing land and upper sealing land. The undeflected inner diameter of the lower sealing land is selected so that upon insertion of the stem through the seal, the seal leg deflects outward. The undeflected diameter of the upper sealing land is selected so that it is larger than the undeflected inner diameter of the lower sealing land. The undeflected diameters of additional sealing lands are selected so that they are successively larger than the undeflected inner diameters of the sealing lands below them. Increased fluid pressure in the stem opening causes the seal leg to flex inward causing additional sealing lands to contact the stem.

摘要： A lockdown loading ring mechanism for a dual crossover seal in a pressurized wellhead which comprises a segmented loading ring assembly 60 of a plurality of arcuate segments 60a arranged in circular fashion within the wellhead annulus between the dual sealing devices of a dual crossover seal assembly 40. The ends of adjacent segments are spaced to allow for contraction and expansion of the assembly. Each segment is actuated by at least one holddown screw 66 of a plurality of holddown screws disposed in radial array about the wellhead axis in equiangular spacing and an equal number of holddown screws are employed to actuate each segment. The nose ends 70 of the holddown screws are in abutting engagement with the outer surfaces 63 of the ring segments whereby actuation of the holddown screws drives the ring segments radially inward to where upward and downward facing frustoconical annular surfaces 62, 61 of the loading ring segments engage cooperative camming surfaces 83a, 51a of the energizer rings 83, 51 of the upper and lower sealing devices respectively, and simultaneously apply balanced axially compressive forces to the dual sealing devices to effect their energization and sealing of the wellhead annulus.

摘要： An improved ribbon reinforced honeycomb structure is disclosed wherein an elongate steel ribbon is interposed between successive semi-hexagonal strips which form the familiar hexagonal multi-cellular structure. The width of the ribbon is less than the widths of the strips between which it is interposed. Such improved honeycomb structure may be used to form part of an abradable seal in aircraft gas turbine engines.
