Abstract: 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.

Abstract: The invention relates to a fueling device for fueling the thrusters of a launcher. In characteristic manner, the device comprises: a ground module (20) comprising at least: a ground pipe (22); a ground valve (21); and a ground plate (26) provided with a ground passage (28); an on-board module (30) comprising at least: an on-board pipe (38); an on-board valve (36); and an on-board plate (32) provided with an on-board passage (34); and a hydraulic coupling system (40) between the on-board module (30) and the ground module (20) enabling fluid communication to be established between the ground passage (28) and the on-board passage (34), and a first annular enclosure (50) situated between the on-board plate (32) and the ground plate (26) around the hydraulic coupling system (40) that, when connected to suction, it enables the on-board plate (32) and the ground plate (26) to be held in a connected-together position.
