CA 2220489

A weapon simulator of the kind comprising a combustion chamber (28), means (21, 31) for admitting fuel gas to the combustion chamber, ignition means (23) for igniting fuel gas in the combustion chamber to cause an explosion, an exhaust port (29) in the combustion chamber and outlet valve means (14) for closing the exhaust port and arranged to open rapidly and with audible results in response to explosive pressure rise within the combustion chamber, characterised in that the outlet valve means (14) comprises a collapsible diaphragm (14) and by a breechblock (8, 11) for releasably gripping the collapsible diaphragm whereby the gripped portion of the diaphragm is released on its collapse due to the explosive pressure rise in the combustion chamber.

Un simulateur d'arme comprend une chambre de combustion (28), des moyens (21, 31) pour laisser entrer un gaz combustible dans la chambre de combustion, un moyen de mise à feu (23) pour la mise à feu du gaz combustible dans la chambre de combustion afin d'en provoquer l'explosion, un orifice de sortie (29) dans la chambre de combustion et une valve de sortie (14) destinée à fermer l'orifice de sortie et s'ouvrir rapidement avec un bruit nettement audible lorsque la pression due à l'explosion augmente dans la chambre de combustion. Une caractéristique du simulateur est que la valve de sortie (14) comprend un diaphragme souple (14). Un verrou de culasse (8, 11) permet de tenir d'une manière réversible le diaphragme souple et de le libérer pour permettre son expulsion au moment de l'augmentation de la pression d'explosion dans la chambre de combustion.
