A fueling device for fueling the thrusters of a launcher is disclosed. The device includes a ground module and an on-board module. The ground module having at least: a ground pipe; a ground valve; and a ground plate provided with a ground passage, and the on-board module having at least: an on-board pipe; an on-board valve; and an onboard plate provided with an on-board passage. The device also includes a hydraulic coupling system between the onboard module and the ground module enabling fluid communication to be established between the ground passage and the on-board passage. A first annular enclosure is situated between the on-board plate and the ground plate around the hydraulic coupling system that, when connected to suction, enables the on-board plate and the ground plate to be held in a connected-together position.

The redundant regulation valve for controlling fluid flow comprises a valve body defining a passage for the flow of the fluid, a main throttle element movable by means of a main control device to selectively obstruct the passage, and a redundant throttle element movable by means of a redundant control device. When the valve is in its closed position in normal operation, the main element and the redundant element are in contact with each other. In this normal closed position, the main element is close to its fully-extended position in the closure direction and it obstructs only about half of the passage, while the redundant element is in a position of medium extension. The stroke of the redundant element is such that the redundant element can be controlled to obstruct the entire passage even when the main element is in its fully-open position.
