Valve for paint ball gun

Abstract

A valve for a paint ball gun includes a case and a movable rod is movably received in the case. The movable rod has a first stop, a second stop and a third sop extending radially therefrom. A first chamber and a second chamber are respectively defined between the first and second stops, and the second and third stops. An inlet is defined through a wall of the case and communicates between the first chamber and a pressurized air source, and an outlet is defined through the wall of the case and communicates between the second chamber and the space in the barrel. The movable rod is moved between first and second positions to seal or introduce pressurized air into the barrel of the gun.

1 . A paint ball gun comprising:
 a barrel with a handle connected thereto and a valve located beneath the barrel, a strike rod and a push member located in a space in the barrel, the valve including a case and a movable rod which is movably received in the case, the movable rod having a first stop, a second stop and a third stop extending radially therefrom, a first chamber defined between the first and second stops, an inlet defined through a wall of the case and communicating between the first chamber and a pressurized air source, a second chamber defined between the second and third stops, an outlet defined through the wall of the case and communicating between the second chamber and the space in the barrel, the case having a flange extending inward from an inner periphery thereof and located between the inlet and the outlet, the second stop being in contact with the flange when the movable rod is located at a first position where the first and second chambers are isolated from each other, the third stop being in contact with the flange when the movable rod is located at a second position where the first and second chambers are in communication with each other;   wherein a release hole is defined through the wall of the case and communicates with the second chamber as the movable rod is at the first position, and the release hole is isolated from the second chamber as the movable rod is at the second position.   
   
   
       2 . The paint ball gun as claimed in  claim 1 , wherein an end surface of the first stop is the same as an end surface of the second stop. 
   
   
       3 . The paint ball gun as claimed in  claim 1 , wherein an end surface of the first stop is 80% to 100% of an end surface of the second stop. 
   
   
       4 . The paint ball gun as claimed in  claim 1 , wherein an end surface of the second stop is 80% to 100% of an end surface of the first stop. 
   
   
       5 . The paint ball gun as claimed in  claim 1 , wherein a spring applies a force axially to the first stop toward the second stop. 
   
   
       6 . The paint ball gun as claimed in  claim 5 , wherein a front cap is connected to a front end of the case and the spring is biased between the front cap and the first stop. 
   
   
       7 . (canceled) 
   
   
       8 . The paint ball gun as claimed in  claim 1 , wherein the movable rod is composed of a first part and a second part, the first stop is located at a first end of the first part and the second stop is located at a mediate portion of the first part, a threaded section is formed at a second end of the first part, the second part includes the third stop at a first end thereof and a threaded recess with which the threaded section is engaged. 
   
   
       9 . The paint ball gun as claimed in  claim 8 , wherein a rear cap is connected to a rear end of the case and a second end of the second part movable extends through the rear cap.
