Abstract

La présente addition concerne un dispositif éjecteur télescopique rétractable destiné à éjecter une charge, à partir d'un avion, par une poussée de gaz aussi constante que possible. Les gaz exercent initialement leur action sur des surfaces annulaires supérieures 42A-43A de deux pistons coaxiaux 42-43 et pénètrent à travers une soupape de retenue 45 dans un cylindre creux central 44 en communication par une canalisation 49 avec des cavités 50-51 sous les têtes des pistons pour assurer la rétraction après l'éjection, tandis qu'après butée du piston extérieur en fin de course la pression s'exerce sur la totalité de la surface du piston intérieur 43 pour l'achèvement de l'éjection.
