Modular fluid pressure regulator with bypass

A fluid pressure regulator assembly including a body having a first passageway extending from a first port to a second port, a second passageway extending from a third port to a fourth port, a pressure regulator coupled between the second and third ports for controlling the pressure of fluid flowing from the second port to the third port, and a bypass valve, the body including a housing for the bypass valve, a third passageway extending from the first passageway to the housing, a fourth passageway extending from the housing to the second passageway, the bypass valve controlling 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.

A fluid regulating assembly including an assembly body providing a fluid entry passageway, a fluid exit passageway, a bypass valve communicating with the fluid entry and exit passageways, and a regulator-mounting portion including a fluid entry passageway exit port and a fluid exit passageway entry port, a fluid regulator including a regulator body defining an internal chamber having a diaphragm separating the chamber into a regulating fluid portion and a regulated fluid portion, the regulator body having a regulating fluid port in communication with the regulating fluid portion to receive a regulating fluid pressure signal, the regulator body having a regulated fluid inlet and a regulated fluid outlet in communication with the regulated fluid portion, the regulating fluid inlet being coupled with a source of regulating fluid, the regulated fluid inlet being coupled to the fluid entry passageway, and the regulated fluid outlet being coupled to the fluid exit passageway.

A bypass structure for a fluid pressure regulator of the type having a regulator inlet port and a regulator outlet port communicating in the regulator, the bypass structure including a body having a fluid entry passageway, a fluid exit passageway, a bypass passageway extending between the entry and exit passageways, a bypass valve positioned in the bypass passageway and movable between a first position to block fluid flow through the bypass passageway and a second position permitting fluid flow through the bypass passageway.

A fluid regulating assembly including a pressure regulator, a body including a fluid entry passageway communicating fluid from a fluid supply source to the pressure regulator, a fluid exit passageway communicating fluid from the pressure regulator to an exit port, and means for diverting a portion of the fluid from the pressure regulator.
