ES248455A1 - Espoleta for underwater explosive loads (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Expoleta for underwater explosive charges characterized in that it is essentially constituted by a piston on which the hydrostatic pressure acts that located in the upper central part of the device is provided at its lower end with an explosive capsule and a fulminantea so that when it falls on the percutorsituado in the lower part of the fuze provoke the explosion of the charge; this piston being retained in its position by means of two balls partially entering a circular groove having the piston at its external upper part. Said balls are kept sunk in the throat by the pressure exerted on them by springs in spiral in whose opposite ends to the balls are placed pivotesque as they are more or less sunken towards the center in the holes in which they lodge pressures more or less to the balls against the throat of the plunger and therefore the hydrostatic pressure necessary for said piston to be released from the grip of the balls and fall to cause the explosion will be greater the more the pivots are pressed. The regulation of this pressure of the springs on the balls is achieved by a rotating outer casing provided with two eccentric inner projections whose protrusion grows from zero to the maximum projection, so that when turning the cascade pivots that press the springs may not exert any pressure at zero point or increase it at will to the maximum point which then constitutes a trip safety so that it is possible by the calculated rotation of the casing to fix the depth at which the hydrostatic pressure will explode the charge.
