ABSTRACT:
A variable pressure solenoid (VPS) control valve. The VPS control valve includes an hydraulic section and a magnetic section. The hydraulic section includes a movable valve that receives a pressurized fluid and generates a control pressure, and the magnetic section controls the operation of the movable valve. The movable valve includes an inlet ball valve for limiting the flow of pressurized fluid into the hydraulic section and an exhaust valve for limiting the exhaust of pressurized fluid out of the hydraulic section. The magnetic section includes a spring-biased armature, and an electromagnetic coil for generating a variable electromagnetic field in response to an electrical input signal for moving the spring biased armature.
