Abstract: An electronic external bypass for a shock assembly is disclosed herein. The electronic external bypass has a compression side fluid connection, a rebound side fluid connection, and an external bypass fluid flow path physically separate from the shock assembly, the external bypass fluid flow path fluidly coupling the compression side fluid connection with the rebound side fluid connection. The electronic external bypass includes a solenoid circuit, the solenoid circuit to control a flow of a working fluid through the external bypass fluid flow path, the solenoid circuit includes a poppet valve and an active valve configured to control a pop pressure of the poppet valve, such that the solenoid circuit provides an infinitely adjustable bypass pressure for the shock assembly.

Abstract: A method and apparatus are disclosed for cooling damping fluid in a vehicle suspension damper unit. A damping unit includes a piston mounted in a fluid cylinder. A bypass fluid circuit having an integrated cooling assembly disposed therein is fluidly coupled to the fluid cylinder at axial locations that, at least at one point in the piston stroke, are located on opposite sides of the piston. The cooling assembly may include a cylinder having cooling fins thermally coupled to an exterior surface of the cylinder and made of a thermally conductive material. The bypass channel may include a check valve that permits fluid flow in only one direction through the bypass channel. The check valve may be remotely operated, either manually or automatically by an electronic controller. A vehicle suspension system may implement one or more damper units throughout the vehicle, controlled separately or collectively, automatically or manually.

Abstract: A damper assembly with a bypass for a vehicle comprises a pressure cylinder with a piston and piston rod for limiting the flow rate of damping fluid as it passes from a first to a second side of said piston. A bypass provides a fluid pathway between the first and second sides of the piston separately from the flow rare limitation. In one aspect, the bypass is remotely controllable from a passenger compartment of the vehicle. In another aspect, the bypass is remotely controllable based upon one or more variable parameters associated with the vehicle.

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.
