Abstract
An electro-hydraulic valve assembly includes a center pole mounting an electric solenoid assembly and slidably received in a valve boss. The solenoid assembly controls the fluid pressure in a chamber defined in the center pole. Fluid in the chamber is biased against a deflectable disc which controls fluid flow through the valve assembly. Control of electric current to the solenoid assembly controls fluid pressure in the chamber and, thus, fluid flow through the valve assembly. When utilized with a damper and a controller, the present valve assembly provides continuously variable damping in real time.
