Abstract

Improvements in the construction of a non-rotating projectile fuze, intended to be launched especially by a mortar, which allows either an instant fire of the projectile on impact, or a delayed firing by prior regulation of the fuze, this comprising a primary bait (34) destined to be set to fire on impact by a firing pin (15) fixing this primary bait (34) to a primary bait holder (32, 33) subjected to the action of a spring (35) which tends to push it axially in the armed position towards the firing pin (15), but kept in a position away from it by a locking device (38-40, 43--48) capable of being unlocked under the effect of axial acceleration due to the firing starting, this fuze further comprising a detonator safety device comprising a secondary bait (59) fixed to a secondary bait holder (64) movable transversely with respect to the axis of the fuze, subject triggered by a spring (68) that tends to bring the secondary bait (59) in front of the detonator (5, 6), sending a clockwork movement (80-84) the passage of the secondary bait holder (64) from its position secured to its armed position, this clockwork movement (80-84) comprising a toothed sector (75) subjected to the action of a spring (76) blocking an axially movable stop (57) at the moment of firing, this toothed sector (75) in the fuze rest position, characterized in that this stop is formed by a second hammer (57) capable of setting the secondary bait (59) on fire once it is in the armed position, this second being carried hammer (57) by a counterweight (55) capable of sliding axially in the primary bait (32, 33) against the action of a spring (56), making a ball locking mechanism (60) integral with each other, the primary bait holder (32, 33) and the said counterweight (55) in both the projecti He has not suffered an impact after the start of the shot, an impact that causes the escape of the blocking balls (60) allowing the counterweight (55) and, thus, the second striker (57), to be pushed by its spring (56), with delay, against the secondary bait (59).
