  • Publication number: 20210206220
    Abstract: A method and apparatus for a shock absorber having a damping fluid compensation chamber with a gas charge. In one aspect, a partition separates a first chamber portion from a second chamber portion, wherein the first portion of the chamber is at a first initial gas pressure and the second portion of the chamber is at a second initial pressure. A valve separates the first and second chamber portions and opening the valve comingles the first and second chamber portions so that the combined chamber portions are at a third pressure. In another aspect, a piston disposed through a wall is in pressure communication with the gas charge and is biased inwardly toward a pressure of the charge, whereby an indicator is movable by the piston in response to the pressure.

  • Patent number: 10975929
    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.

  • Publication number: 20210079973
    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.

  • Publication number: 20210025472
    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.
