A damper assembly of the piston and cylinder type

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 via a collar 19 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.
