Shock absorber

摘要

An improved shock absorber for a vehicle suspension system that incorporates an internal damping arrangement that permits a smooth transition between first and second damping rates. The mechanism includes a metering rod that is mounted in such a way that it will self-adjust in its position relative to a bore extending through the piston rod. An arrangement is disclosed for mounting the pistons on the piston rod so as to permit control of their positions without necessitating threaded adjusting devices.
