Patent 7798174 was granted and assigned to Eaton Corporation on September, 2010 by the United States Patent and Trademark Office.
A solenoid operated valve has a separate pressure sensing port communicating with the valve outlet port. A circuit board with a pressure transducer mounted over a sensing orifice in the board is attached to the valve body with the sensing orifice communicating with the sensing port in the valve body. The transducer thus provides a feedback signal indicative of the valve outlet pressure.
