ABSTRACT:
The invention relates to a nail driving tool, acting by means of an explosive charge, which, besides the normal component parts, comprises an explosion chamber of particular shape and volume, whereby a blow applied to the rear end of the tool causes the explosive charge, compressed by the rear end of the nail driving piston in the explosion chamber, to reduce the volume of the latter according to a predetermined ratio, which reduction, in turn, originates the ignition of the explosive charge.
