SECURE ACTUATION DEVICE FOR A PRESSURIZED GAS SUPPLY CONTAINER IN AN AIRCRAFT

Abstract

Title: SECURE ACTUATION DEVICE FOR A PRESSURIZED GAS SUPPLY CONTAINER IN AN AIRCRAFT This secure actuation device for a gaseous oxygen supply container in an aircraft to distribute this oxygen to a user, said container (1) being intended to store pressurized oxygen at a first oxygen pressure and having an opening (2) sealed by a sealing gasket (9); the device comprising a manifold (4) connected in fluidic communication with said sealing joint (9) and configured to receive an oxygen flow from said opening (2) when the sealing joint (9) is pierced, said manifold (4) comprising an oxygen flow circuit (11) connected in fluidic communication with said sealing joint (10) and having an outlet (14) at a second oxygen pressure lower than the first pressure and a regulator (13) having oxygen pressure regulation means (12,15,16) between the opening (2) and said outlet (14) during a flow; and an actuator (7) in the opening (2) configured to pierce said sealing joint (9) when triggered so as to permit oxygen flow through the opening (2) from the container (1) to the outlet (14), the oxygen flow circuit (11) comprising a calibrated orifice (17) provided at the outlet (14) configured to prevent any accumulation of oxygen at a third pressure between the first and second pressures in the event of oxygen flow to said outlet (14) in the absence of triggering of the actuator (7).
