Abstract: An energizing element including: an energizing element body oriented about a central axis, the energizing element body defining an inner radius, IR, and an outer radius, OR, where the difference between the outer radius and the inner radius defines an adjusted width, W, of the energizing element body, where the inner radius and the outer radius determine an average radius, R, of the energizing element body about the central axis, where the energizing element body defines an aspect ratio, W/R, where W/R>0.1, where the energizing element body has a maximum linear contact length on the inner radius, LIR, where the energizing element body has a perimeter on the inner radius, PIR, and LIR/PIR>0.80, where the energizing element body has a maximum linear contact length on the outer radius, LOR, where the energizing element body has a perimeter on the outer radius, POR, and LOR/POR>0.55, and where the adjusted width is less than 5 mm.

Abstract: Systems and methods include providing a seal for an assembly. The seal includes a jacket having a base, an inner sealing leg, and an outer sealing leg, and further includes a spring disposed within the jacket between and in contact with the inner sealing leg and the outer sealing leg. The spring includes an annular support ring disposed within the spring. The support ring biases an outer diameter (OD) of the spring towards the outer sealing leg of the jacket to maintain contact pressure between the inner sealing leg of the jacket and the shaft of the assembly. The support ring controls thermal shrinkage of the spring and the outer sealing leg to maintain a seal between a housing and a shaft of the assembly when the assembly is operated at cryogenic temperatures.
