Abstract:
A hydraulic valve is provided that includes an interior spool and a surrounding cage. A supply port and a return port are connected to the cage and the interior of the cage is in fluid communication with a control port. The interior spool is positioned between an on and off position using a solenoid and a spring. In the off position, slots in the spool and cage align to place the return port in fluid communication with the interior of the spool. Conversely, in the on position, different slots in the spool and cage align to place the supply port in fluid communication with the interior of the spool.
