Abstract

rotary nozzle, own for small caliber projectiles, bearing oscillating at point (5) capable of oscillating about an axis perpendicular to the axis of the nozzle, and in which an open case (7) containing (8) intended to ensure the ignition of another pyrotechnic composition (1) when impact, and this movable element (5) is arranged in front of the pyrotechnic composition so that it is to ignite (1) and arranged in such a way as to energy of the centrifugal forces is caused by the rotation of the projectile, and to move due to its rearrangement, from an active position which the output of said case (7) is revealed in relation to the .......... composition is to be ignited (1), in an active position in which said output is opposite to said ......... of the composition or It is to be ignited (1), characterized in that, on the one hand, the oscillating element (5) is thus fixed in the body of the fire tube (3), so that this is possible, at least from the moment the exit of the case (7) is relative to the pyrotechnic composition or to be ignited (1), to be displaced parallel to the axis of the nozzle between a predetermined return position at which the oscillating element (5) is preferably in contact (10) with the element after the charge of which is to be ignited (1), so that at its regression position there is a substantially continuous communication between the ignition starting composition (8) and the composition which is to ignite (1), on the other hand. the oscillating element (5) is subjected to the action of retracting means (7) by pushing it backwards and exerting a force sufficient to hold it in place
