DEPTH CHARGE FUZE

摘要

Depth charge fuze, comprising a piston (12) in a cylinder (11) sealingly and displaceably guided to actuate a firing mechanism (13, 14) against atmospheric pressure within the cylinder on one side of the piston. The piston is operatively connected to a balancing device (28, 29) for balancing in axial direction. At the other side of the piston there is provided a pressure chamber (36) connected to the surroundings by means of a number of throttling passages (26) with valves (38) depending on the surrounding water pressure for closing up the passages on different levels of water pressure. A shearing means (21) retains the piston in a rest position up to a predetermined maximum pressure drop over the piston.
