Spring-loaded, hollow, elliptical ring seal

摘要

A canted-coil spring-loaded ring seal assembly including a plurality of coils having a major and a minor axis and canted along a center line defined by an intersection of the major and minor axes along with an elastic material, disposed around and between said plurality of coils and having a hollow cross-section, for modifying the force exerted by the spring assembly in response to deflection of the spring assembly along said loading direction and for providing a sealing surface. The plurality of coils and elastic material are noninvasively supported in an orientation for controlling the resilient characteristics of the plurality of coils and for orienting said sealing surface for sealing contact with a loading member.
