Pressure control mechanism for fireguns

Abstract

The present invention relates to a pressure control structure that is developed to be used in semi-automatic firearms operating with gas pressure, that allows for using any type of live ammunition (small/magnum) easily by maintaining the stability of the gas pressure created as a result of firing the firearm and enables cocking the rifle mechanism, that protects the parts of the rifle as well as the assembly thereof and that provides the user a more comfortable firing experience.

1 . A pressure control structure for firearms, comprising:
 at least one gas discharge port that enables adjusting the gas pressure by being opened and closed; and   a gas chamber where on its wall the gas discharge port is positioned, such that the gas chamber does not come into contact with a gas piston.   
     
     
         2 . The pressure control structure for firearms of  claim 1 , wherein the gas chamber has at least one gas chamber lug that incorporates a hole running along the length of the gas chamber and a bolt handle seat located inside of the gas chamber lug. 
     
     
         3 . A pressure control structure for firearms, comprising at least one bolt handle, wherein one end of the bolt handle is positioned in a gas chamber and extends to at least one gas discharge port. 
     
     
         4 . The pressure control structure for firearms of  claim 3 , wherein another end of the bolt handle extends to a firearm chassis. 
     
     
         5 . The pressure control structure for firearms of  claim 3 , wherein one end of the bolt handle that extends to the gas discharge port moves inside of a gas chamber lug. 
     
     
         6 . The pressure control structure for firearms of  claim 3 , wherein the bolt handle further comprises at least one bolt handlebar that is positioned on one end of the bolt handle such that the bolt handlebar further allows fixing of the position of the bolt handle. 
     
     
         7 . The pressure control structure for firearms of  claim 6 , wherein the bolt handle has at least one bolt handlebar positioning hole that allows positioning of the bolt handlebar to the bolt handle. 
     
     
         8 . The pressure control structure for firearms of  claim 6 , wherein the bolt handle has at least one ball setscrew hole formed on the bolt handle and adjacent to the bolt handlebar positioning hole. 
     
     
         9 . The pressure control structure for firearms of  claim 8 , wherein the bolt handle has at least one ball setscrew that is inserted into the ball setscrew hole. 
     
     
         10 . The pressure control structure for firearms of  claim 3 , wherein the bolt handle has a stepped shaft structure such that the stepped shaft structure has a wider structure than the rest of the bolt handle structure. 
     
     
         11 . The pressure control structure for firearms of  claim 6 , wherein a firearm chassis has at least two bolt handle positioning holes into which the bolt handlebar can be seated, in order to fix the position of one end of the bolt handle located inside a bolt handle seat and also to fix the position of the other end of the bolt handle located in the firearm chassis. 
     
     
         12 . The pressure control structure for firearms of  claim 4 , wherein the firearm chassis has a bolt handle seat. 
     
     
         13 . The pressure control structure for firearms of  claim 4 , wherein the firearm chassis has at least one bolt handle spring that is connected to the bolt handle by being positioned in the firearm chassis.
