Abstract

A fuse-less shell (10) with a so-called pyrotechnic impact fuse achieves bore safety and safety in front of the bore by providing a spring-supported ball (43) arranged in a central bore (72) within a valve body (65). The valve body (65) separates an explosive charge (60) at the shell side from an impact-sensitive firing charge (28). The firing charge (28) is disposed within a shell cap (24) and surrounds a projection (30), which acts as an anvil, of the valve body (65).
