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).
Claims6
A safety device for a pyrotechnic impact fuse of a ballistic high explosive shell, comprising a pyrotechnically reactive material which is initiated upon impact, wherein a ball safety device only passes into the armed position after launch of a shell, and wherein
- a central initiation passage (72) is arranged in a penetration passage of a valve body (65) and is provided with a ball guide (42) with spaced end abutments (44, 75) for a ball (43) mounted therein,
- and lateral firing passages (41) open into the central initiation passage (72) behind the ball (43) in the armed position,
- characterized in that
- a prestressed spring element (73) is disposed between the ball (43) and the abutment (75) which faces towards a secondary explosive charge, and
- the ball (43) in the safe position seals off the initiation passage (72) with the lateral firing passages (41) opening into the initiation passage (72), against firing vapors flowing therethrough.
