PROPORTIONAL CONTROL VALVE WITH DIFFERENTIAL SENSING AREA |
摘要 |
An electrically actuated valve for regulating a working pressure of a closed volume load includes an inlet valve (24) for controlling fluid flow between a supply port (16) and a working port (18) and an outlet valve (26) for controlling fluid flow between the working port (18) and an exhaust port (20). A solenoid actuator (70) applies an adjustable force to a movable valve element (44) for closing the outlet valve (26) and opening the inlet valve (24). The adjustable force is opposed by a reactionary force that is generated by the working pressure. The movable element (44) includes opposing areas exposed to the working pressure for scaling the reactionary force to the working pressure. |
