Bullet delivery device for air guns

Abstract

A bullet delivery device for an air gun includes strike rod which is moved by a spring when the trigger is pulled and a spiral section is connected to the strike rod so that the pressurized air is guided and accelerated via the spiral groove to deliver the bullets out from the chamber of the barrel.

1 . An air gun comprising: 
 a handle and a barrel connected to the handle, a trigger connected to the barrel;    a strike assembly received in the barrel and including a strike bar which has a pull end extending from a rear end of the barrel and a push member connected with the strike bar, a pawl pivotably connected to the barrel and the push member including a groove so that the pawl is removably engaged with the groove, the pawl being pivoted by the trigger, a strike rod having a first end fixed to the strike bar and a second end of the strike rod having a spiral section, the spiral section located in a chamber in the barrel, a first spring connected between the attached member and an end cap connected to the rear end of the barrel;    a valve assembly received in the barrel and including a tubular member and a piston movably extending through an axial passage of the tubular member, a gap defined between the piston and an inner periphery of an aperture defined through the tubular member, a first end of the piston extending out from the tubular member and facing the push member, a second end of the piston fixed to a seal which is biased by a second spring so as to removably seal the aperture of the aperture in the tubular member, a radial hole defined through a wall of the tubular member and communicating with the chamber of the barrel, and a magazine connected to the barrel and adapted to feed bullets into the chamber of the barrel.    
   
   
       2 . The air gun as claimed in  claim 1 , wherein the piston has a flat surface defined in an outside thereof and the gap is defined between the flat surface and the inner periphery of the aperture of the tubular member.  
   
   
       3 . The air gun as claimed in  claim 1 , wherein the strike rod has a threaded section on the first end thereof and the strike bar has a threaded hole defined therein so that the threaded section is connected to the threaded hole.  
   
   
       4 . The air gun as claimed in  claim 1 , wherein the second end of the piston includes a threaded end and the seal has a threaded hole with which the threaded end is connected.  
   
   
       5 . The air gun as claimed in  claim 1 , wherein the strike bar is located parallel to the push member, a pin connected between the strike bar and the push member.
