Abstract
A pressure regulator in the form of a proportional pressure control solenoid provides predictable and repeatable control of pressure in response to an electrical input signal. The pressure regulator converts the electrical control signal to an output pressure at the load independent of the flow requirements. The electromagnetic portion of the pressure regulator generates a force proportional to the average current supplied by a controller and applies that force to the hydraulic components of the device. The hydraulic components include a spool and a feedback pin which apply a pressure feedback force to the solenoid.
