Abstract
The present invention refers to a dual pressure regulation system to ensure a proper pressure regulation during the Aerial REFUELING operations with Hose and Drogue systems. More specifically is directed to dual redundant fuel pressure regulation systems. The pressure regulator system comprises two pressure regulators (10, 20) located in series and a control element (30) for controlling the movement of both regulators operatively connected downstream (34) the second pressure regulator (20) such that the movement of the pressure regulators (10, 20) is independently controlled by the control element (30) according to the delivery pressure downstream the second regulator (20).
