摘要

Subcalibre perfected for mortars characterized in that the tube that determines the subcaliber itself has coupled at their ends separate bodies of which the upper one has a general annular conformation while the inferior cazoletacumple functions as the base of that determining both bodies by its periphery a sliding fit between them and the anima of the canyon in the achievement of a perfect operative positioning of the subcalibre; at the same time, each one of them presents a correlation of openings, establishing a passage for the gases that, at the moment of firing, can pass through the contact zones that are established inferiorly between the subcaliber and the mortar barrel, thus avoiding the action of said gases the subcaliber and the consequent thrown of this to the outside.
