A pressure sensor is mounted integrally in a hydraulic valve body. The sensor has a base which extends into a bore formed in the valve body. The valve body bore is in communication with a pressurized hydraulic fluid. A first circumferential groove formed in the sensor base carries an O-ring which forms a seal between the sensor and the wall of the valve body bore. A second circumferential groove formed in the sensor base carries a spring ring which extends into a corresponding groove formed in the wall of the valve body groove. The spring ring cooperates with the sensor base and valve body bore grooves to retain the sensor in the valve body bore.
A pressure sensor for a hydraulic control system comprising:
A sensor according to claim 2 wherein said circumferential groove is a first groove and said base portion has a second circumferential groove formed therein, said second circumferential groove having a spring ring disposed therein, said spring ring adapted to cooperate with a complementary groove formed in said hydraulic valve body bore to retain the sensor in said valve body bore.
A method for installing a pressure sensor into a hydraulic valve body comprising the steps of:
