The invention relates to a system for correcting pogo oscillation for a system for supplying liquid propellent to a rocket engine, comprising a supply duct portion (70) for supplying liquid propellent, a hydraulic accumulator (11), comprising a vessel (12) connected to the supply duct portion (70) by at least one collection passage (15), in which the vessel (12) comprises at least one first and one second cavity (20, 30), each closed by an upper wall (21, 31), the upper wall (21) of the first cavity (20) extending at a level higher than that of the upper wall (31) of the second cavity (30), wherein the first and second cavities (20, 30) are each provided with a separate gas supply (22, 32), the gas supply (32) of the second cavity (30) at least being controllable, wherein the second cavity (30) comprises at the upper end thereof at least one communication passage (14) connecting same to the first cavity (20), and wherein each cavity (20, 30) is connected to the supply duct portion (70) by at least one exhaust passage (23, 33) leading into said cavity (20, 30) at an intermediate level (24, 34) comprised between said at least one collection passage (15) and the upper wall (21, 31) of said cavity (20, 30), the exhaust passage (33) of the second cavity (30) leading into the second cavity (30) at a level lower than the level at which the exhaust passage (23) of the first cavity (20) leads into the first cavity (20).
