ABSTRACT:
A simple momentary contact diverter valve is operated directly by axially disposed solenoid operators at each end of an elongated valve housing having a bore passing therethrough to receive a valving spool therein in an operable relationship with said solenoid operators so as to enable spool shifting directly to result in diversion of fluid flow passing therethrough between fluid supply and exhaust ports incorporated therein, energization of operator coils electrically accomplished momentarily by an application of voltage-overcharge-pulse to yield higher than conventional magnetic force resulting in more than conventionally accepted pull force spool experiences, thereby increasing capability of handling fluid pressures substantially above those attainable by direct solenoid operated valves of this type.
