Abstract
A solenoid-operated pressure-fluid valve for reversible control of both supply and exhaust functions of a double-acting fluid-pressure device. A valve body has an inlet port communicating with an inlet chamber and an exhaust-outlet port communicating with an outlet chamber. The valve body has first and second control-port connections for connection to the respective control ports of the double-acting device, and each of these connections communicates with a valve seat in each of the chambers. A rocker arm is pivoted between the two chambers and carries two valve members in each of the two chambers. In one solenoid-actuated position of the rocker arm, valve-member action in the inlet chamber establishes inlet-chamber communication exclusively with one control-port connection while the valve-member action in the outlet chamber establishes outlet-chamber communication exclusively with the other control-port connection; in the other solenoid-actuated position, valve-member action in the respective chambers is such as to reverse the exclusivity of chamber communication with the respective control-port connections.
