Percussion controlling mechanism of paintball guns

Abstract

A percussion controlling mechanism of paintball guns includes a percussion member and an air valve separately installed in a gun body. A main air passage is located in front of and separated from the air valve by a spring. Located behind the air valve is a driving chamber having a driving member. An air sub-passage is formed under the air valve chamber for communicating with the main air passage. A driving valve is installed in a grip to correspond to the driving chamber, having an ever-opened buffering hole communicating with a front end of the driving chamber and the air sub-passage, and a driving hole communicating with a rear end of the driving chamber. By means of the air sub-passage to provoke a difference of pressure in the driving chamber, the backlash of percussion can be greatly lowered to boost speed of continuous shooting.

1 . A percussion controlling mechanism of paintball guns, said guns respectively including a gun body and a grip integrally extended from a bottom of a rear end of said gun body, said percussion controlling mechanism comprising a percussion chamber and an air valve chamber formed separately divided in said gun body, said percussion chamber provided with a paintball inlet bored in its top, a percussion member installed behind said paintball inlet and inserted with a bolt and dug with a percussion air passage, said air valve chamber provided with an air valve, a main air passage formed at a front portion of said air valve chamber and separated from said air valve by a spring, an valve hole bored in a top of said air valve for corresponding to said percussion chamber, a driving chamber formed behind said air valve and provided with a driving member installed inside it, a through hole and a driving hole formed between said percussion chamber and said air valve chamber and communicating to each other, said bolt inserted through said driving hole to position in said driving member, said percussion controlling mechanism characterized by;
 an air sub-passage separately positioned under said air valve chamber and having its one end communicated with said main air passage and another one communicated with said driving chamber so as to transmit air in said main air passage into said driving chamber; and   a driving valve installed in said grip to correspond to said driving chamber and provided with an ever-opened buffering hole and a driving hole, said ever-opened buffering hole having its one end communicating with a front end of said driving chamber close to said air valve and another one communicating with said air sub-passage so as to let said air sub-passage transfer buffering air to run into said driving chamber, said driving hole communicating with said driving chamber behind said driving member for air to run through to push said driving member toward said air valve, a vent positioned at one side of a bottom of said driving valve to correspond to said ever-opened buffering hole.   
   
   
       2 . The percussion controlling mechanism of paintball guns as claimed in  claim 1 , wherein said air valve is provided with a valve base, a valve hole bored in said valve base for corresponding to said percussion chamber, an opening recessed in said valve base for communicating with said valve hole, a valve rod axially and pivotally installed in said valve base and having its front and rear portion extended in said air valve chamber, a valve cap mounted on said valve rod to correspond to said opening. 
   
   
       3 . The percussion controlling mechanism of paintball guns as claimed in  claim 1 , wherein said driving chamber is provided with a linking block mounted on a front portion of said driving member to correspond to said air valve chamber, said bolt inserted in said linking block and said percussion member to keep them linked with each other, a driving rod having its front portion connected to a rear portion of said linking block and its rear portion extended in said driving chamber so as to have a buffering gap formed between its circumference and said driving chamber for communicating with said ever-opened buffering hole, a driving block positioned at a rear end of said driving rod and having an outer diameter equivalent to an inner diameter of said driving chamber so as to have a driving gap formed between its rear end and said driving chamber  30  for communicating with said driving hole. 
   
   
       4 . The percussion controlling mechanism of paintball guns as claimed in  claim 1 , wherein said main air passage has its opening sealed with a pressurized bottle.
