Abstract
A solenoid-operated hydraulic control valve is disclosed which may be employed in a fuel injection system for an internal combustion engine. The hydraulic control valve has a valve plunger which is drawn by a solenoid when turned on for selectively establishing and blocking fluid communication between an inlet and an outlet. A fluid chamber is formed to which fluid pressure is supplied from the inlet. The fluid pressure in the fluid chamber acts on the valve plunger in a direction opposite to that of the attracting force of the solenoid when turned on for compensating the attracting force produced by residual magnetism in the solenoid immediately after the solenoid is turned off.
