Abstract
A sound signal body, for generating underwater sound signals, that includes an explosive body which can be thrown out or released by hand. Within the explosive body is arranged an explosive charge as well as a hand grenade detonator having a pyrotechnical delayed detonator composition. The detonator is explodable at the head of the explosive body by a hammer. The sound signal body is provided with a hydraulic pressure switch which comprises a pressure chamber, at least one inlet which empties into the pressure chamber, and a membrane or diaphragm. The diaphragm is connected with a release bolt, which, through the diaphragm and dependent upon the pressure of the water flowing into the pressure chamber, is movable out of a safety position into an armed position. The sound signal body is further provided with a locking mechanism, by means of which it is possible, on the one hand, to arrest the hammer which, against the force of a torsion spring, is deflected in a safety position, as well as, on the other hand, to release the hammer, after obtaining a specific water pressure within the pressure chamber, in cooperation with the release bolt, by relaxing the torsion spring.
