Title of the Invention Electrically controllable valve assembly Abstract of the Disclosure An electrically controllable valve assembly for hydraulic adjustment of a piston includes a pilot valve controllable by an electronic controller. The pilot valve has a spool and a restrictor array comprising first and second variable restrictor means and a fixed restrictor means, through which flows an auxiliary bleedflow of hydraulic fluid. The variable restrictor means are adjusted in opposite directions in order to produce form the bleed flow a control pressure which is responsible for positioning of the piston of the valve assembly. A pressure drop is taken off at the fixed restrictor means, and acts on the spool to produce a negative feedback action, thereby always to produce a given displacement control flow, irrespective of the system pressure, while avoiding control oscillations.
