Measures are provided for the gas to expand within the fuse and the energy of the rotor fragments used up so that the gas expanding direction and the flight direction of the fragments face away from the explosives of the intensifying charge. Expansion chambers are formed by recesses in the fuse for safety devices adjacent the rotor, such as different centrifugal force-dependent safety devices for the firing pin which are separated from each other by breaking locations destroyable by the gas.Field of SearchCentrifugal and setback operatedWith or including a timing device Rotor or slide with setback release Firing pin is latch Centrifugal operated With or including a timing device Latch for impacting device Spiral band Pivoted weight Expanding weight Rotor or slide Centrifugally released latch Deceleration released latch | |
