Definitions

the invention relates to a projectile detonator with a securing element which releases an igniter carrier under the action of centrifugal force.
the securing element is formed by a spiral band, which, when secured by means of a spring clip, holds an ignition needle that blocks an igniter carrier. Under the action of centrifugal force, the spiral band widens and the firing pin releases the igniter carrier, which then rotates into focus.
the object of the invention is to propose a projectile detonator of the type mentioned at the beginning, in which the securing element is insensitive to impacts and ensures that the pipe is secure.
the above task is for a floor Igniter of the type mentioned solved in that the securing element is a piston guided in a cylinder formed on the igniter body, that the piston has a passage opening whose cross section is small compared to the cross section of the piston and that the piston under centrifugal force is a medium filling the cylinder pushes from one side of the piston to the other side of the piston.
the piston in the cylinder is moved outwards. This movement is gradual as the piston is braked. It can only move in the unit of time by a distance that corresponds to the volume of the medium pressed through the passage opening.
the securing element thus only releases the igniter carrier after a delay. Among other things, this depends on the cross-section of the flow opening and the viscosity of the medium.
a liquid is preferably used as the medium.
Shocks acting on the projectile body are damped by the medium in such a way that the igniter carrier is not released by shocks.
a cylinder 2 is formed in an igniter body 1.
a piston 3 is mounted in this.
a locking piece 4 is formed on the piston 3. In this sits a compression spring 5, which is supported on a sealing washer 6, which closes the cylinder 2. A pin 7 for guiding the compression spring 5 is provided on the sealing disk 6.
the piston 3 is sealed by means of a sealing ring 8 in the cylinder 2.
a sealing ring 9 seals the locking piece 4.
the piston 3 has a passage opening 10, the cross section of which is considerably smaller than the cross section of the piston 3.
the cylinder 2 is filled with a liquid 11.
An igniter carrier 12 is mounted in the igniter body 1 and has a recess 13 into which the locking piece 4 engages to ensure it.
the locking piece 4 of the piston 3 has left the recess 13.
the igniter carrier 12 then moves into the focus position, in which the ignition can then take place. Adequate safety of the front pipe is guaranteed by the braked piston movement.
