<p>A pressure sensor (10,55,70,90,105) is mounted integrally in a hydraulic valve body (40,60,92). The sensor has a base (11,65,71) which extends into a bore (41,58,91) formed in the valve body. The valve body bore is in communication with a pressurized hydraulic fluid. A first circumferential groove (15,97,98) formed in the sensor base carries an O-ring (45,95,96) which forms a seal between the sensor and the wall of the valve body bore. A second circumferential groove (14,100) formed in the sensor base carries a spring ring (46,101) which extends into a corresponding groove (43,102) formed in the wall of the valve body bore. The spring ring (46,101) cooperates with the sensor base and valve body bore grooves to retain the sensor in the valve body bore. <IMAGE></p> |
