Abstract
A proportional fluid pressure regulation system is provided using a combination of a proportional valve and a shuttle valve for fluid flow control. A system of fluid pressure regulation is achieved where the desired pressure output is provided by one of two pressure input sources. The two pressure input sources are alternately selected by operation of a pilot operated shuttle valve and a solenoid operated proportional valve. The two pressure sources may comprise a manually actuated vehicle braking system's master cylinder and a power operated fluid pump.
