A vehicle suspension damper including: a cylinder; a piston assembly; and an adjuster, wherein the piston assembly compresses fluid as it moves within the cylinder and the adjuster obstructs fluid flow from a first side of a damping piston of the piston assembly to a second side of the damping piston.

There is provided a front fork which has a small number of components with simple structure and is easy to assemble. In order to achieve the above object, in a front fork F according to the means for solving the problem of the present invention, first and second adjusters 5, 6 are mounted on a cap 4 so as to be axially movable, and a contact portion 52 of the first adjuster 5 in contact with a first adjustment rod 7 and a contact portion 62 of the second adjuster 6 in contact with a second adjustment rod 8 are displaced in an axial direction of a vehicle body tube 2 so as not to interfere with each other. Therefore, even when each of the first and second adjusters 5, 6 moves in the axial direction with respect to the cap 4, the corresponding first and second adjustment rods 7, 8 can be moved independently without being interfered with each other.

A vehicle suspension damper including: a cylinder; a piston assembly; and an adjuster, wherein the piston assembly compresses fluid as it moves within the cylinder and the adjuster obstructs fluid flow from a first side of a damping piston of the piston assembly to a second side of the damping piston.

The present invention relates to a valve arrangement particularly, but not exclusively, for use in dampers to control compression and optionally rebound properties of a shock absorber wherein the valve arrangement comprising a valve body having a first and second fluid flow pathway for enabling fluid flow from an upstream to a downstream location and the valve arrangement further comprises a plurality of operational configurations for controlling the flow rate of fluid flow.

A vehicle suspension damper includes: a cylinder and a piston assembly, wherein the piston assembly includes a piston; a working fluid within the cylinder; a bypass cylinder surrounding the cylinder and defining a cylindrical bypass channel; an adjustable bypass port fluidly coupling an interior of the cylinder and the cylindrical bypass channel; and an active bypass valve coupled with the cylindrical bypass channel, the active bypass valve configured to adjust a working size of the adjustable bypass port to modify a flow of said working fluid through the adjustable bypass port.

The present invention discloses a dynamically adjustable suspension device including one or more springs having similar or different spring rates, where said one or more springs are arranged in a pre-defined configuration, and a dynamically adjustable damper. The dynamically adjustable damper, includes a rotatable knob coupled to the dynamically adjustable damper to change the damping coefficient dynamically in real-time, means to rotate the knob so as to adjust damping coefficient in real-time while the dynamically adjustable suspension device being used, means to identify compression of the one or more springs by sensing one or more positions of the springs, between a fully elongated state and a fully compressed state in real-time.

A vehicle suspension damper includes: a cylinder and a piston assembly, wherein the piston assembly includes a piston; a working fluid within the cylinder; a bypass cylinder surrounding the cylinder and defining a cylindrical bypass channel; an adjustable bypass port fluidly coupling an interior of the cylinder and the cylindrical bypass channel; and a remotely operable bypass valve slidably disposed within the cylindrical bypass channel, the remotely operable bypass valve configured for, upon actuation of an actuator coupled with the remotely operable bypass valve, adjusting a flow of the working fluid through the adjustable bypass port.

A vehicle suspension damper including: a cylinder; a piston assembly; and an adjuster, wherein the piston assembly compresses fluid as it moves within the cylinder and the adjuster obstructs fluid flow from a first side of a damping piston of the piston assembly to a second side of the damping piston.

A damper assembly is provided that includes a housing and a rotor. The housing includes a cavity and a groove. The groove is configured for passage of damping fluid. The damper assembly defines a proximal end configured for mounting to an actuator and a distal end configured for the passage of the damping fluid, and the groove is disposed at the distal end of the cavity. The groove extends along a groove length and has at least one of a variable width or variable depth. The rotor is disposed within the housing and rotatably articulable with respect to the housing. The rotor includes a displacement member that articulates with rotation of the rotor relative to the housing along the groove length to direct the damping fluid through the groove.

A damper valve with an adjustable effective stiffness of a shim. The damper valve includes a piston. The piston has a fluid path formed therethrough. A shim is disposed proximate the fluid path formed through the piston. A stiffness adjustment feature is coupled to the shim, and the shim is disposed between the piston and the stiffness adjustment feature. The stiffness adjustment feature is configured to adjust the effective stiffness of the shim without affecting a preload applied to the shim.
