摘要： A rotary seal assembly for preventing leakage of a fluid from a region of high pressure in a housing to a region of relatively lower pressure includes a first member mounted within the housing and having a central axis and an annular sealing face extending in a direction substantially radial the central axis, and a second member located in the housing and having an annular sealing face extending in a direction substantially radial to the central axis and opposing the first member sealing face. The second member sealing face has a first set of grooves and a second set of grooves arranged circularly thereabout, the second set of grooves being spaced radially inward of the first set of grooves. One of the first and second members is a rotor and the other is a stator. A stator holding assembly supports the stator within the housing, the rotor being rotatable about the central axis. The stator holding assembly secures the stator against rotation and urges the stator sealing face toward the rotor sealing face. Pressurized fluid flows between the sealing faces and within the first and second set of grooves, thereby forming a gas film seal between the sealing faces.
摘要翻译：用于防止流体从壳体中的高压区域泄漏到相对较低压力的区域的旋转密封组件包括安装在壳体内并具有中心轴线的第一构件和沿着基本径向的方向延伸的环形密封面中心轴线和位于壳体中的第二构件，并且具有环形密封面，该环形密封面在基本上径向于中心轴线的方向上延伸并与第一构件密封面相对。第二构件密封面具有第一组凹槽和在其周围布置的第二组凹槽，第二组凹槽与第一组凹槽径向向内间隔开。第一和第二构件中的一个是转子，另一个是定子。定子保持组件支撑壳体内的定子，转子可围绕中心轴线旋转。定子保持组件固定定子以避免旋转，并将定子密封面推向转子密封面。加压流体在密封面之间和第一和第二组凹槽之间流动，从而在密封面之间形成气膜密封。

摘要： A seal assembly includes a first plate or member having a recess with a bottom mating surface which receives sealing ring therein and a second plate or member having a sealing surface for contacting a metallic sealing ring. First and second plates or members are coupled together by a plurality of fasteners or bolts. By tightening the fasteners the sealing ring is loaded, and thus, compressed to plastically deform and create an annular seal between the first and second members. Metallic sealing ring has a first annular sealing surface, a second annular sealing surface, an annular inner surface and an annular outer surface. The first annular sealing surface faces in a first axial direction to contact sealing surface of first member for creating a first annular sealing dam therebetween. The second annular sealing surface faces in a second axial direction, which is opposite to the first axial direction of the annular sealing surface, to contact sealing surface of second member for creating a second annular sealing dam therebetween. Preferably, the first and second annular sealing surfaces are substantially flat surfaces which are parallel to one another. An annular column section is formed between the first and second annular surfaces. The minimum radial width of the annular column determines the force necessary to deform the sealing ring to its sealing position. A pair of beam sections extend substantially perpendicular to the column section to create the sealing surfaces. At least one brace extends diagonally between the column section and one of the between sections to obtain proper sealing during compression of the sealing ring.

摘要： A stationary assembly for use in a gas or liquid seal for sealing an interface between a machine body and a rotatable shaft. The stationary assembly includes an annular seal ring attached to the machine body and surrounding the shaft. An annular seal ring housing secures the seal ring and includes a plurality of bores. Each bore retains a spring. A circumferentially flexible "O" ring holder receives the springs. The "O" ring holder presses an "O" ring against a balance diameter surrounding the shaft and the seal ring to provide a seal. The "O" ring holder includes a plurality of slots formed therein and arranged to provide the circumferential flexibility.
