Fluid e.g. hydraulic oil, ejection device for use as e.g. emergency hydraulic generator, in aircraft, has valve in end part adopting closed configuration in presence of gas in reservoir to ensure sealing of enclosure

摘要

The device has a gas generator (7) generating pressurized gas, and a separation unit (5) located between an end part and a fluid (14) to form enclosures (A, B) of a reservoir (1). A communication unit communicates the reservoir with the generator so that gas passes into the enclosure (A). A valve (12) in the end part adopts an open configuration in the absence of gas in the reservoir so as to release the air from the enclosure (A) with outer environment irrespective of axial position of the unit (5) and a closed configuration in the presence of gas in the reservoir to seal the enclosure (A).
