Obturator for firearms

Abstract

An obturator ( 100 ) for firearms comprises: a structure ( 101 ); a closing head ( 102 ), in particular a rotary one, arranged at an end ( 103 ) of the cylindrical structure ( 101 ); at least a resting surface ( 104 ) defined on the closing head ( 102 ) to engage the bottom (F) of at least one cartridge (C); at least one through channel ( 105 ) extending longitudinally through the cylindrical structure ( 101 ) for operatively engaging at least one striker of the firearm. The obturator comprises deformation means ( 108 ) associated with the closing head ( 102 ) to at least partially deform a firing capsule ( 109 ) and/or a bottom of a cartridge (C) loaded on the firearm.

1 . Obturator ( 100 ), for firearms comprising:
 a structure ( 101 );   a closing head ( 102 ), arranged at an end ( 103 ) of said cylindrical structure ( 101 );   at least a resting surface ( 104 ) defined on said closing head ( 102 ), said resting surface ( 104 ) being adapted to engage the bottom (F) of at least one cartridge (C),   at least one through channel ( 105 ) developing longitudinally through said cylindrical structure ( 101 ) for operatively engaging at least one striker of said firearm, said through channel ( 105 ) having, at said resting surface ( 104 ) of said closing head ( 102 ) at least one opening ( 106 ),   characterised in that it comprises deformation means ( 108 ) associated to said closing head ( 102 ) adapted to deform, at least partially, the bottom and/or the firing capsule of said cartridge (C).   
     
     
         2 . Obturator according to  claim 1 , wherein said deformation means ( 108 ) are arranged at said resting surface ( 104 ) of said closing head ( 102 ). 
     
     
         3 . Obturator according to  claim 2 , wherein said deformation means ( 108 ) comprise at least a surface relief ( 108   a ) projecting from said resting surface ( 104 ) of said closing head ( 102 ). 
     
     
         4 . Obturator according to  claim 3 , wherein said surface relief ( 108   a ) extends, on said resting surface ( 104 ) of said closing head ( 102 ) according to a ring-shaped development. 
     
     
         5 . Obturator according to  claim 4 , wherein said surface relief ( 108   a ) substantially surrounds said opening ( 106 ) of said through channel ( 105 ); 
     
     
         6 . Obturator according to  claim 5 , wherein said surface relief ( 108   a ) extends according to a substantially circular development. 
     
     
         7 . Obturator according to  claim 6 , wherein said surface relief ( 108   a ) has a profile, along a section plane extending longitudinally with respect to said cylindrical structure ( 101 ), tapering away from said resting surface ( 104 ) of said closing head ( 102 ).
