Abstract: A fluid activated shaft bulkhead seal system includes an annular carrier fixed with respect to a bulkhead and about a shaft extending through the bulkhead and the annular carrier. The annular carrier supports a pair of lip seals each of which defines an outwardly facing pocket and a lip portion spaced from the shaft and a portion abutting the carrier. A foam body is disposed in the pocket of each lip seal. Each foam body includes a gel material configured to expand in the presence of fluid urging the lip portions of the lip seals into contact with the shaft to seal the annular carrier with respect to the shaft. An annular retainer is mated to each side of the annular carrier for retaining the foam body in the pocket of each lip seal.

Abstract translation: 流体激活的轴舱壁密封系统包括相对于隔板固定的环形载体，以及围绕延伸穿过隔板和环形载体的轴。 环形托架支撑一对唇形密封件，每个唇形密封件限定向外的凹穴和与轴间隔开的唇部部分和邻接托架的部分。 泡沫体设置在每个唇形密封件的口袋中。 每个泡沫体包括凝胶材料，其被配置为在存在流体的情况下膨胀，从而将唇形密封件的唇部部分与轴接触，以相对于轴密封环形载体。 环形保持器配合到环形承载件的每一侧，用于将泡沫体保持在每个唇形密封件的口袋中。
