The contour may define at least one of a polygon and a polygon-like shape.

Abstract: A valve assembly includes a valve body defining an inner volume, a flow controller positioned within the inner volume, a plug positioned within the inner volume, and a biasing element. The plug is spaced from the flow controller such that an intermediate chamber is defined between the plug and the flow controller. The biasing element is positioned in the intermediate chamber between the plug and the flow controller. The plug is repositionable within the inner volume. As the plug moves within the inner volume, the plug interacts with the biasing element such that the biasing element provides a biasing force to the flow controller.

The load alleviator 10 includes at least one bias spring 42 to resiliently bias cam followers 18 and cam surfaces 22 together and to maintain them in locked engagement unless a predetermined load is exceeded whereupon a center housing 12 is pivotal or rotational with respect to a crown assembly 14.

The energy dissipator 16 can be provided to dissipate substantially more energy from the overload force than from the bias force that automatically resets the center housing 12 and crown assembly 14 to the normally fixed centered alignment. The torsional and bending (moment) overload levels can designed independently of each other.

Abstract: A hollow torsion bar reinforced by a mixture of resin and filler and method of making such a torsion bar. The torsion bar is formed from mild or medium grade steel seamless or welded tubing. The tubing is cut to length and charged preferably with a mixture of substantially uncured thermoset resin and plastic or glass hollow microspheres and/or metal pellets. The mixture may be charged into the tube by injection as a paste or by placing inside the tube a B-stage form insert having preferably between about 10 and 50 percent elongation tensile strength. After the tube has been charged with the reinforcing mixture, the tube is bent to form a torsion bar having a radius arm and a spring portion. In areas that the torsion bar is bent, the reinforcing mixture is provided to act as an internal mandrel preventing collapse of the tube walls. The mixture is then cured and bonded in place by chemical reaction of the rein or by thermally curing the resin mixture within the tube.
