Damper Assemblies

摘要

A damper assembly comprises a piston and cylinder type damper with a piston (14) mounted for reciprocal movement in a cylinder (10) containing damping fluid. The piston (14) is acted on by a piston rod (11) which comprises a reaction surface for engaging the piston. The cross-sectional area of the reaction surface is designed to be significantly greater than the cross-sectional area of the piston rod (11) in order to spread the load exerted on the piston (14). Also, the piston (14) is designed to engage the piston rod (11) at its inner end in a manner that provides lateral guidance for the inner end of the piston rod in its movement in the cylinder (10).
