ABSTRACT:
A control valve that has a pair of solenoids which move a spool between first and second positions. The spool and housing are constructed from a magnetic steel which maintains the spool in either the first or second position. The spool is located within a valve chamber of a housing which has at least two fluid ports. The valve controls the flow of fluid between the ports in accordance with the position of the spool. The valve can be constructed to be either a two-way, three-way or a four-way valve. The spool has an inner chamber which is in fluid communication with both the valve chamber and the drain port of the valve. The inner chamber insures that the ends of the spool are balanced and that a hydraulic pressure does not build up in the valve chamber.
