INTERCHANGEABLE CHOKE TUBE FOR THE CONSTRICTION OF THE PELLETS OF THE LOAD OF SMOOTHBORE SHOTGUN WITH ARRANGEMENT OF CUTS WHICH ALLOW THE ELASTIC TYPE EXPANSION OF ITS MUZZLE

摘要

Interchangeable choke tube for the constriction of the pellets of the load of smoothbore shotgun with arrangement of cuts which allow the elastic type expansion of its muzzle (7), which has at his protruding front section (4) a suitable number of cuts (8) of proper design which begin at its nozzle front end and extend towards the rear, dividing its nozzle into non-connected at their front parts sections (9), which allow its under pressure expansion during the passage of the shot charge through it in a flexible manner. Acts in such a way that between the shot charge and the constriction section (6) only the necessary to achieve the desired effect pressure is developed with each time particular stenosis degree, relieving the excess pressure by the enlargement of its nozzle which is kept within the limits of each time particular constriction degree, improving the distribution uniformity of the shot pattern.
