  • Publication number: 20120136537
    Abstract: A shock absorber includes a gas spring cylinder containing a piston moveable between an extended position and a compressed position within the gas spring cylinder. A mechanical actuator is arranged whereby a bleed port is automatically closed when the gas spring is compressed to a predetermined position corresponding to a desired sag setting. In one embodiment, the position corresponds to a predetermined sag setting whereby the gas spring is partially compressed. In another embodiment, a proper sag setting is determined through the use of a processor and sensor that in one instance measure a position of shock absorber components to dictate a proper sag setting and in another instance calculate a pressure corresponding to a preferred sag setting.

  • Publication number: 20120080279
    Abstract: A method and apparatus for adjusting the sag setting of a vehicle suspension are disclosed. An integrated damper/gas spring shock absorber includes a bleed port located at a position on a gas spring cylinder corresponding to a desired sag setting. The gas spring may be over pressurized to a pressure above the expected operating pressure of the gas spring. The vehicle may then be loaded with the normal operating load, partially compressing the shock absorber. Opening the bleed port allows gas to vent from the gas spring, further compressing the shock absorber until a piston in the gas spring closes the bleed port from the inner surface of the gas spring cylinder. A sleeve may be inserted over the gas spring cylinder, the sleeve including one or more sealing elements that seal the bleed port from the outer surface of the gas spring cylinder during normal operation.

  • Publication number: 20100308516
    Abstract: A method and apparatus for a vehicle shock absorber comprising a main damper cylinder, a first reservoir and a second reservoir. One embodiment includes a first operational mode where both reservoirs are in fluid communication with the cylinder. In a second operational mode, only one reservoir communicates with the cylinder during fluid evacuation from the cylinder. In each mode, rebound from either or both reservoirs may travel through a single, user-adjustable metering device.
