Abstract
A pressure compensated solenoid valve with fluid flow force balancing is provided. The solenoid valve includes an armature and a valve plunger arranged to transport hydraulic fluid from a supply end of a valve plunger to an upper end of the armature facilitating a resultant upper fluid force that acts upon the upper end of the armature to balance a resultant lower fluid force that acts on the supply end of the valve plunger. The solenoid valve includes a poppet that is configured as a pressure-relief valve for maintaining a minimum fluid pressure within an actuation fluid gallery. An inlet fluid force of the poppet is balanced by an outlet fluid force of the poppet.
