摘要
The device has a screen (10) formed by semi-screens (10a, 10b) i.e. cylindrical rods, slidingly mounted in a bore carried by a rotor (14) coaxial to a spin-stabilized explosive missile. The semi-screens are locked in a closing position of a transmission channel (11) via a centrifugal lock and an inertial lock i.e. ring (26), that is removed during firing of the missile. The centrifugal lock comprises a spiral spring (24) surrounding an external cylindrical surface of the rotor and applied against ends of the semi-screens, where spiral of the spring is unwound under centrifugal force effect. The spiral of the spring is in a form of portion of sphere. An independent claim is also included for a priming device comprising a detonator.
