Abstract
A mechanical bypass for a shock assembly is disclosed herein. The assembly has a damper chamber having a compression portion and a rebound portion. There is further an external reservoir in fluid communication with the rebound portion of the damper chamber via a flow path. A valve is coupled with the flow path, the valve to meter a flow of the working fluid through the flow path. A bypass port to the external reservoir is provided in the flow path and bypasses the valve. A mechanical relief valve is provided in the bypass port to block a fluid flow though the bypass port until a blow-off pressure that is higher than a normal operating pressure and less than a burst pressure of the damping chamber is provided thereon.
Claims11
An assembly comprising:
- a damper chamber having a compression portion and a rebound portion;
- a damping piston coupled to a piston shaft, said damping piston disposed in said damper chamber and axially movable relative to said damper chamber, said damping piston separating said compression portion from said rebound portion;
- an external reservoir in fluid communication with the rebound portion of the damper chamber via a flow path, the external reservoir to receive and supply a working fluid as the damping piston moves in and out of the damper chamber;
- a valve coupled with said flow path, said valve to meter a flow of said working fluid through said flow path;
- a bypass port to the external reservoir formed in the flow path and bypassing the valve;
- a mechanical relief valve provided in said bypass port to block a fluid flow though said bypass port until a blow-off pressure that is higher than a normal operating pressure and less than a burst pressure of said damper chamber is provided thereon;
- and
- a bottom out feature having a flow rate adjustable by an active valve, and wherein said active valve controls fluid flow from said compression portion of said damper chamber through said bottom out feature, said active valve configured to automatically adjust said flow rate.
