Abstract
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.
