Abstract[English]
A feed unit for feeding hydrogen to a hydrogen propulsion system (2) has a hydrogen storage tank (3), a hydraulic circuit (4) for connecting the tank (3) to the propulsion system (2), and a valve device (5) fitted in the hydraulic circuit (4) for controlling the hydrogen feed from the tank (3) to said propulsion system (2), the valve device (5) having two control valves (6, 7) fitted in parallel with each other in the hydraulic circuit (4), one of which valves can be moved between a closed position and a single or plural open position(s), while the other can be moved between a closed position and at least two open positions.[French]
L'invention concerne une unité d'alimentation pour alimenter en hydrogène un système de propulsion à hydrogène (2) qui comprend un réservoir de stockage d'hydrogène (3), un circuit hydraulique (4) permettant de raccorder le réservoir (3) au système de propulsion (2), et un dispositif de soupapes (5) ajusté dans le circuit hydraulique (4) pour commander l'alimentation en hydrogène à partir du réservoir (3) audit système de propulsion (2), le dispositif de soupapes (5) comprenant deux soupapes de commande (6, 7) montées en parallèle l'une avec l'autre dans le circuit hydraulique (4), l'une de ces soupapes pouvant être déplacée entre une position fermée et une ou plusieurs positions ouvertes, tandis que l'autre peut être déplacée entre une position fermée et au moins deux positions ouvertes.
