One embodiment of a spring with an integral dynamic gas seal according to the present invention includes a spring with a pair of spaced-apart ends and a spring body extending therebetween. The spring body includes a perimeter wall formed of a first material and extending in a longitudinal direction.
One embodiment of a spring with an integral dynamic gas seal according to the present invention includes a spring with a pair of spaced-apart ends and a spring body extending therebetween. The spring body includes a perimeter wall formed of a first material and extending in a longitudinal direction. The wall has a plurality of openings defined therein. The openings are provided in a plurality of transverse tiers. Each tier includes a plurality of separate openings each extending along a portion of the perimeter. The openings in each tier are spaced apart so as to define a post between each adjacent opening such that each tier includes a plurality of posts. The openings in each tier are staggered with respect to the openings in adjacent tiers such that each of the openings in each tier overlie one of the posts in an adjacent tier. A closure member closes each of the openings such that the spring body is sealed. The closure member is formed of a second material having a different degree of flexibility than the first material.
