Abstract:
A spring unit for installation in a pivot pin assembly. The spring unit including a pair of disc springs each with an axially centered aperture and each with, when in an uncompressed condition, a concave side and a convex side. A retaining element, such as an adhesive, retains the disc springs to a returning member such that the spring unit can be easily installed in the pin assembly as a unit. The spring unit further includes a centering structure whereby the disc springs can be centered about the pin assembly when fully compressed.
