Abstract (en)
[origin: FR2892851A1] Chamber (1) has a mobile assembly (10) axially moving between starting and final positions of operation of opening a circuit-breaker. The assembly has a compression chamber (5) whose volume diminishes between the starting position and an open position of the chamber (5). A compression chamber (13) communicating with the chamber (5) presents volume diminishing between the starting and final positions. The chamber (13) injects a dielectric gas (3) into the chamber (5) between the open and final positions when the pressure inside the chamber (5) is less than that in the chamber (13).
