Abstract

Underwater fishing gun, having a vacuum system for projecting the spear (13) and using the pressure exerted by the external ambient on the piston (8) of one or more hollow cylinders (1) as force for the projection, constituted by a stem (3), a grip (5), a firing mechanism (4), a barrel (9) or a guide (15) for the spear (13), and a certain number of cylinders (1) each containing a piston (8) connected to the firing mechanism (4) or to the spear (13) by means of the above-mentioned barrel (9) or by means of a bar (14).The vacuum within each cylinder (1) is obtained manually by pulling the bar (14) or pushing the barrel (9) towards the rear portion of the gun. The piston (8), fixed on the bar (14) and on the barrel (9) is displaced within the cylinder (1), thus creating the vacuum.When it is decided to operate the projecting of the spear (13), the barrel (9) or the spear (13) is actuated, and the piston (8), pushed by the ambient pressure, immediately returns to its initial position, indirectly carrying with it the spear (13) and imparting to it the force necessary to project it.
