Abstract
A solenoid actuator comprising an armature member that engages a spool including a spool cap on an end of the spool that is axially movable relative to the spool. A bore in the spool allows fluid to flow from a control port to the spool cap, such that pressure is established in the spool cap. The pressure established in the spool cap acts on the spool with a force directly proportional to the control pressure and the fluid-contacting area inside the spool cap.
