Abstract

The projectile fuse adjustment mechanism comprises a first piezo-electric component (26) which as the result of the firing of the projectile charges partly an ignition capacitor (4), partly a reservoir capacitor (1,2), and a second piezo-electric component (25) acting as stop detector. The reservoir capacitor (1,2) forms part of an regulating circuit containing a primary electronic current regulator (20) whose control input is connected to the second piezo-electric component (25), and a time circuit (3,5) the output of which is connected to the control input of a second electronic current regulator (8). A second reservoir capacitor (21) is charged by the first (1,2) to ensure that the primary current regulator (20) receives adequate base current supply. A trigger diode (6) makes the second current regulator (8) conductive when a predetermined voltage level is achieved in the time circuit (3,5), enabling the ignition capacitor (4) to discharge through the fuse (27).
