A shock absorber comprises an adjustment component movable in two degrees of freedom. When the adjustment component is adjusted within one of its degrees of freedom of movement, a characteristic, such as the compression damping, is adjusted and when the adjustment component is adjusted within the other of its degrees of freedom of movement another characteristic, such as the rebound damping, is adjusted. The invention extends to a method of adjusting the operation of a shock absorber.

The present invention is directed to shock absorbers with damping adjusters which vary the damping provided during compression and rebound strokes. The shock absorber includes a cylinder within which a piston is movably mounted for movement within the cylinder. Bypass openings open into the cylinder interior at axially spaced-apart positions. The bypass openings are coupled by a bypass channel. A pressurized gas container is fluidly coupled to the cylinder interior with a movable barrier separating the pressurized gas container and the cylinder interior. Compression and rebound damping adjusters may be used.

The present invention is directed to shock absorbers, including position-sensitive shock absorbers (2) in which the position-sensitive damping can be different during compression and rebound strokes, and shock absorbers (60) with damping adjusters (80, 118) which vary the damping provided during compression and rebound strokes. The position-sensitive shock absorber includes a cylinder (4) within which a piston (122) is movably mounted for movement between the first and second ends of the cylinder. Bypass openings (24-32) open into the cylinder interior (6) at axially spaced-apart positions. The bypass openings are coupled by a bypass channel (38). A flow valve (40, 42) may be positioned along the bypass channel permitting fluid flow from the first opening to the second opening and restricting fluid flow from the second opening to the first opening. A pressurized gas container (18) may be fluidly coupled to the cylinder interior with a movable barrier (14) separating the pressurized gas container and the cylinder interior.

A vehicle damper is described. The vehicle damper includes: a cylinder; a piston within the cylinder; a working fluid within the cylinder; a reservoir in fluid communication with the cylinder via the working fluid, the reservoir operable to receive the working fluid from the cylinder in a compression stroke; a valve in a flow path between the cylinder and the reservoir; and a remotely-operable valve having a position allowing the working fluid to significantly by-pass the valve.

A system for controlling vehicle motion is described. The system includes: a first set of sensors coupled with a vehicle, the first set of sensors configured for sensing the vehicle motion; and a vehicle suspension damper coupled with the first set of sensors, the vehicle suspension damper configured for adjusting a damping force therein, the vehicle suspension damper comprising: a primary valve; a pilot valve assembly coupled with the primary valve, the pilot valve assembly configured for metering a flow of fluid to the primary valve, in response to at least the sensing; and an orifice block coupled with the primary valve and comprising a control orifice there through, the control orifice configured for operating cooperatively with the pilot valve assembly in the metering the flow of fluid to the primary valve.

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 fluid pathway between the first and second sides of the piston separately from the flow rate 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.

A gas spring shock absorber (10) includes a damping fluid cylinder (14) telescopically housed within a gas cylinder (12). A shaft (16) connects a sealed, outer end (18) of the gas cylinder (12) with a vented piston (32) movably mounted within damping fluid cylinder (14). Shaft (16) passes through a sealed inner end (28) of damping fluid cylinder (14) so that a sliding seal (34) located between gas cylinder (12) and damping fluid cylinder (14) creates a sealed variable-volume gas cylinder (40) between the cylinders.

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 commingles 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.
