Bypass for a suspension damper

摘要

A vehicle suspension damper comprises a cylinder and a piston assembly including a damping piston along with working fluid within the cylinder. A bypass permits fluid to avoid dampening resistance of the damping piston. A fluid path through the bypass is controlled by a valve that is shifted by a piston surface when the contents of at least one predetermined volume is injected against the piston surface which acts upon the valve. In one embodiment, the bypass is remotely operable.

1. A vehicle suspension damper comprising:
a cylinder containing a fluid and a damping piston operable to travel within the fluid in the cylinder, said vehicle suspension damper further including a passageway through the damping piston and limiting a flow rate of the fluid through the damping piston in at least one direction; a bypass pathway in fluid communication with the cylinder between a first and second side of the damping piston; a valve for controlling a flow of the fluid through the bypass pathway, the valve including a piston surface biasing the valve towards a closed position when displaced; and at least one predetermined fluid volume in selective communication with the piston surface for causing displacement; wherein the valve is remotely controllable.
