Abstract
A spring seat for self aligning a bias-open or bias-close spring is disposed within a tubular control element of a gas regulator and designed to reduce side loading of the spring, which can cause the spring to prematurely fail. The spring seat can comprise a spring seat adaptor and a seat ring. The spring seat adaptor is fixed inside of the tubular control element and the seat ring is movably mounted on the spring seat adaptor via a ball and socket type joint. The movable seat ring is engaged by the spring and adapted to be self-aligned through three-dimensional displacement relative to the spring seat adaptor via the ball and socket joint.
