  "textContent": "A valve, controlling pressure differential by regulating fluid flow between a tank and a canister, includes: a valve opening; a first moving element carrying a first sealing device making a leaktight seal and movable relative to the valve opening between a closed and an opened position allowing a first flow between the tank and the canister, through a first passageway with a first size; a second moving element carrying a second sealing device making a leaktight seal and movable relative to the valve opening between a closed and an opened position allowing a second flow between the tank and the canister, through a second passageway with a second size. The second moving element includes a central hole having a frustoconical surface partly defining the first passageway. The first sealing device has a complementary frustoconical surface cooperating with the frustoconical surface of the central hole of the second moving element.",
