<p>The invention relates to an active part (1) comprised in an ammunition device, such as a shell, missile or the like. According to the invention, the casing (2) of the active part is provided with a sleeve (10) in association with the opening (3) of the casing. A sprung device (14) is arranged between a locking device (6) arranged at the opening (3) of the casing and the sleeve (10). The end of the sleeve facing away from the sprung device is in direct contact with an explosive charge (4) arranged inside the casing of the active part or with a liner (5) arranged on the surface (20) of the explosive charge which is facing towards the sleeve and the locking device. The locking device (6) is designed to be released from the casing by the action of a force. By means of the invention, an active part is achieved which, in normal use, manages to keep the active part intact even if materials in the active part have greatly varying coefficients of thermal expansion, while at the same time, in extreme temperatures, the active part is prevented from detonating by the locking device (6) being released from the casing.</p> |
