Abstract

A projectile fuse includes a carrier for an igniter. The carrier is held in a safety position by a safety element, which under the effect of centrifugal force moves to release the carrier. The safety element comprises a piston guided in a bore formed in the fuse body. The bore is filled with a flowable medium. The piston is provided with an orifice for enabling the medium to flow from one end of the piston to the other under the effect of the centrifugal force. The medium thus brakes the movement of the piston and creates a time delay before the carrier is released.
