Abstract
A shock absorber includes a first cylinder having a first fluid port and a second cylinder having a second fluid port. A response adjustment mechanism is connected in fluid transmission relation between the first and second fluid ports.The response adjustment mechanism includes three adjustable valves for controlling the operation of the shock absorber. One of the adjustable valves has a stem that is rotatable by a tool during operation. The remaining adjustable valves each have a shaft that is rotatable by a tool during operation.The adjustable valves of the response adjustment mechanism are coaxially positioned so that a first valve is coaxially positioned within a second valve, and the first and second valves are coaxially positioned within a third valve.
