Abstract: A bi-directional cryogenic rotary valve having a housing defining a fluid passageway, a control member rotatably disposed within the fluid passageway, and a seal assembly positioned along an inner surface of the housing to provide a bubble tight seal between the housing and the control member. The rotary valve adapted to operate at or near cryogenic temperatures (i.e., at −160° C.) while maintaining an affective seal in both the forward and reverse directions. The rotary valve being capable of retrofitting against wear and operational stress sustained from repeated use and operation.
Abstract translation: 双向低温旋转阀，其具有限定流体通道的壳体，可旋转地设置在流体通道内的控制构件和沿着壳体的内表面定位的密封组件，以在壳体和控制构件之间提供气密密封 。 旋转阀适于在低温或接近低温（即-160℃）下操作，同时在正向和反向方向上保持情感密封。 该旋转阀能够改进反复使用和操作所产生的磨损和操作应力。

Abstract: A seal assembly is disclosed. The seal comprises a metal spring bonded to an elastomer body that is coupled to a polymer ring. The spring may comprise a cantilevered, overlapped metal strip. The elastomer and polymer mechanically interlock with radial members. The elastomer has contacting surfaces configured in outward extending radii to enhance forward edge loading and oil removal from the dynamic surface. In hydraulic service, the seal prevents the egress of hydraulic fluid and ingress of foreign particles.
