Electric fluid servo valve and method of making same

摘要

A solenoid operated valve has a separate pressure sensing port (30) communicating with the valve outlet port (16). A circuit board (38) with a pressure transducer (36) mounted over a sensing orifice in the board (38) is attached to the valve body (12) with the sensing orifice communicating with the sensing (30) port in the valve body (12). The transducer thus provides a feedback signal indicative of the valve outlet pressure.
