The present invention relates to a pressure-sensitive device for arming a fuze for a projectile. It is previously known to mount on projectiles various kinds of diaphragms or pistons with sealing piston rings for this purpose. However these devices often have an unsatisfactory function. The invention involves a solution to the problem by having a piston mounted in the projectile wall, in sealing contact with a sleeve made of softer material than the piston. When exposed to a high outer gas pressure the piston is pushed into the sleeve and deforms it during which a very good sealing is maintained. The movement of the piston is used to carry out a predetermined arming measure. |
