Abstract
A fluid pressure regulator assembly includes a body having a first passageway extending from a first port to a second port, and a second passageway extending from a third port to a fourth port. A pressure regulator is coupled between the second and third ports for controlling the pressure of fluid flowing from the second port to the third port. The regulator assembly further includes a bypass valve and the body includes a housing for the bypass valve. A third passageway extends from the first passageway to the housing, and a fourth passageway extends from the housing to the second passageway. The bypass valve controls flow from the first passageway through the third passageway and the fourth passageway to the second passageway in response to a bypass control signal coupled to the bypass valve.
