Abstract

Ensemble de cartouche comportant un support de projectile 10 adapté pour maintenir en place de façon détachable un projectile; une chambre de pression de forme allongée 12 adaptée pour contenir du gaz comprimé; un élément formant passage 13 s'étendant entre le support de projectile 10 et la chambre de pression 12; un dispositif formant valve 14 adapté pour permettre le transfert du gaz de la chambre 12 au dispositif 13, en vue de propulser un projectile à partir du support 10, lorsque la chambre de pression se déplace vers et relativement au support 10; un élément de rappel 15 logé dans la chambre 12 pour appliquer directement ou indirectement une force tendant à fermer le dispositif à valve 14. Cet ensemble comporte en outre un espace 16 formé entre la chambre de pression 12 et une paroi formant barrière 17 à l'extérieur du support de projectile 10 adjacente à la chambre de pression 12; et un évent ou conduit d'aération pour annuler la contre-pression dans ledit espace 16.A cartridge assembly comprising a projectile holder 10 adapted to releasably hold a projectile in place; an elongated pressure chamber 12 adapted to contain compressed gas; a passage member 13 extending between the projectile support 10 and the pressure chamber 12; a valve device 14 adapted to allow the transfer of gas from chamber 12 to device 13, in order to propel a projectile from support 10, as the pressure chamber moves to and relative to support 10; a return element 15 housed in the chamber 12 for directly or indirectly applying a force tending to close the valve device 14. This assembly further comprises a space 16 formed between the pressure chamber 12 and a wall forming a barrier 17 to the valve. exterior of the projectile support 10 adjacent to the pressure chamber 12; and a vent or aeration duct for relieving back pressure in said space 16.
