The invention concerns a device for setting the ignition timing in projectile fuses. The device comprises a timing ring rotatable around the front-to-rear axis of the fuse for setting the ignition time.
From German Pat. No. 22 00 540, a device for setting the timing of a projectile fuse is known. The disclosure of that patent is incorporated herein by reference. The device consists of a stationary point, a rotatable part and a stationary lower part. The rotatable part comprises a timing ring and is used to get a predetermined ignition time or ignition delay. The timing ring may be rotated by a maximum of 360.degree. and is equipped with a device whereby it is possible to set even longer time delays with a full rotation. To prevent the unintentional resetting of the set ignition time or delay time during subsequent manipulation of the fuse, special measures are usually effected by means of threaded bolts located on a circular ring.
A disadvantage of this arrangement involves the fact that, firstly, the assembly is relatively complex. Secondly, a nonuniform screwing-in of the bolts cannot be entirely prevented; the axial forces are fully applied to the individual threaded bolts and therefore deformations on the housing cannot be entirely avoided.
It is an object of the invention to provide a device of the afore-mentioned type, whereby the time setting torque customarily used in time fuses may be set exactly, and additionally a positive connection of the center and lower parts of the housing is possible.
