Hydraulic, tappet actuated ejection device with automatic recharging system

摘要

The device comprises a pneumatic accumulator 22 linked to a pressurised gas source 16 by the intermediary of a non-return flap valve 23 which only allows the pressurised gas to pass in the direction going from the feed duct 20 towards the accumulator 22. The latter is linked by ducts 25, 26, 27 to chambers for retracting the ejection jacks 6, 7. A sequencing valve 24, in parallel with the non-return flap valve 23, automatically short-circuits the non-return flap valve at the end of the phase of recharging the ejection tappets 8, 9 whilst draining the recharging ducts 25, 26, 27. The device applies to the recharging of ejection tappets equipping assemblies for releasing and ejecting missiles. IMAGE
