Definitions

  • the invention relates to a safety device for a rotor of an igniter, in particular a rocket igniter, in which an air storage space is provided, in which a piston is mounted and wherein a slide engages the piston, which locks the rotor in the rest position of the piston and it in the displaced position of the piston releases.
  • a safety device for an igniter of the type mentioned is known from US-A-4,380,179.
  • This known device requires electro-mechanical interlocks to control the movement of a piston.
  • a piston within a cylinder head divides the central cylindrical chamber into an upper and lower volume, which are arranged airtight to one another.
  • pressure is built up so that the piston is displaced out of the cylinder head in the direction of the rotor.
  • the slider is disengaged from the rotor so that it can turn into focus.
  • DE-26 40 782 A1 describes a safety device on an igniter in which the rotor carries an ignition means.
  • the rotor is secured by an axially displaceable steady bolt. This bolt releases the rotor when the projectile is fired, whereby a torsion spring rotates the rotor into focus.
  • An air storage space 1 is formed on a detonator. This is connected via a line 2 to an opening, not shown, at the head of the rocket.
  • the dynamic pressure acting on the head when the rocket is launched acts via line 2 in the air storage space 1.
  • the direction of launch is represented by the arrow P.
  • a drive member 24 rotatable on the rotor axis A engages in a toothing 23 of the swivel member 21.
