Abstract
Spring energized seal assemblies each with one or two sealing elements and a canted coil spring located in a spring cavity of the sealing element or of the two sealing elements to bias an inner flange and an outer flange of the respective spring cavity away from one another. The canted coil springs can have un-conventional coil shapes with one or more straight coil segments and/or with curved connecting ends. The coils can have dimples to provide multiple biasing points. The coils can have loops. The canted coil springs with un-conventional coil shapes can be used to improve spring loading on a sealing element.
