Abstract
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.
Claims21
A vehicle suspension damper comprising:
- a cylinder and a piston assembly comprising a piston;
- a working fluid within said cylinder;
- a bypass having a fluid pathway between a first and second sides of the piston;
- a valve for controlling the flow of fluid through the bypass, the valve including a displaceable piston surface, the piston surface biasing the valve towards a closed position when displaced;
- and
- at least two predetermined fluid volumes in selective communication with the piston surface for causing displacement thereof;
- wherein each predetermined volume comprises a valve operating cylinder, the fluid contents of the cylinder injectable into the valve to displace the piston surface and wherein the valve operating cylinders are substantially equal.
