Improvements in safety devices for mu-Definitions

摘要

This invention relates to the safety of ammunitions. The projectile of a cartridge has a base which houses a safety stop consisting of a transversely slidable valve. A device ensures that the valve cannot be released until the projectile has been subjected to a powerful acceleration. Another safety device very advantageously ensures that the pyrotechnical chain inserted in the base functions only when the pressure of the ejection charge has been able to release a sealing-block. In particular, the invention may be applied to infra red window releasing cartridges.
