An electrically controlled valve for a shock absorber. The valve comprises a piston providing a primary fluid channel for damping fluid and a housing in which a piston holder is provided with an internal secondary fluid channel for damping fluid. Fluid flow (23) through the secondary fluid channel for damping fluid. Fluid flow through the secondary fluid channel is controlled by a spool movable within the piston holder wherein the movement of the spool is enabled by an electrically controlled actuator. Fluid flow through the secondary fluid channel is controlled by restriction at the inlet of the secondary fluid channel the inlet comprising one or more radial holes through the piston holder.

External damping adjustment apparatus and method for suspension system
11623712 · 2023-04-11 · ·

A mechanism and method for externally adjusting the mid-valve stiffness is described and enables adjustment of a mid-valve functionality without disassembly of a suspension system incorporating the invention. The effect of this adjustment on the damping curve is far greater than either low-speed compression adjusters or conventional high-speed compression adjusters. The apparatus combines the valve-stiffening system of a high speed compression adjuster with the sensitivity of the mid-valve. Externally accessible adjustment members are operatively coupled to the mid-valve components located internally in a fork so that manipulation of the adjustment members causes adjustment of the mid-valve and the damping force created by the mid-valve. The apparatus may be utilized in closed cartridge suspension forks (CCSF) and open cartridge suspension forks (OCSF) and other shocks or suspension dampers.
