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.

An adjustable valve for a shock absorber comprises a hollow valve body comprising a plurality of valve apertures. A rotatable sleeve is rotatably arranged around at least part of the hollow valve body. The rotatable sleeve comprises a plurality of sleeve apertures. The adjustable valve further comprises a movable spool slidably arranged within the hollow valve body and configured to move relative to the hollow valve body. The movable spool divides the hollow valve body into a first chamber and second chamber. Rotation of the rotatable sleeve relative to the hollow valve body varies an alignment between at least one sleeve aperture of the plurality of sleeve apertures and at least one valve aperture of the plurality of valve apertures. Movement of the movable spool relative to the hollow valve body varies an available opening area of at least one valve aperture of the plurality of valve apertures.

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 gas spring curve control valve for a adjustable-volume gas-pressurized device is described. The valve allows for selection from among at least four spring curves and can be packaged in small spaces/devices. In an exemplary embodiment of the invention, a rotary cam having grooves and lobes that interact with spring loaded ball bearings and an external adjuster knob are used to easily change the gas spring curve on-the-fly and with minimal user effort.

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.
