摘要
Aircraft opening actuator, comprising: - a pneumatic jack (1) for opening the sash, comprising a piston (2) and a chamber (4) in which a gas under pressure is injected via a first ( 5) opening for opening the sash, - means (6) for supplying pressurized gas to the chamber (4) of the jack (1) via a conduit (7) supply connected to the chamber by said first (5) orifice, means (8) for putting the chamber under atmospheric pressure when the piston (2) is in the opening position of the opening, in order to allow said opening to be returned to its position closure system, comprising: - a duct (9) for exhausting the pressurized gas, one end of which is connected to the chamber via the first orifice, and the opposite end of which is connected to the atmospheric pressure, - a valve (10) ) whose body (11) is arranged in series on the exhaust duct (9), and whose shutter (12) opens or closes the exhaust duct - means (13) for controlling the opening of the valve from the pressurized fluid in the cylinder chamber when the opening is in the open position, to open the exhaust duct in order to obtain a quick setting to atmospheric pressure of this cylinder chamber after opening the opening. Application in particular to emergency opening actuators.
