Automatic paint ball gun

Abstract

A paint ball gun has a gun body and a trigger assembly therein. The gun body has a first chamber, a second chamber and a tunnel between the first and the second chambers. A rod, a percussion member and a shaft are provided in the first chamber, the second chamber and the tunnel respectively. A rear block connects the rod and the percussion member. A valve is provided in the first chamber and activated by the rod. A controller is provided in the gun body, has a guiding channel to be manipulative for communication the first chamber and the tunnel and an exhausting channel to be manipulative for communication with the tunnel. The trigger assembly is manipulative to issue the gas in the first chamber to the second chamber for movement the shaft and to exhaust the gas in the tunnel after moving the shaft out.

1 . A paint ball gun, comprising: a gun body with a handle and a trigger assembly installed in the handle, wherein the gun body has a first chamber, a second chamber and a tunnel between the first chamber and the second chamber and a rod is provided in the first chamber, a percussion member is provided in the second chamber and a shaft is provided in the tunnel; a rear block connecting the rod and the percussion member; a valve provided in the first chamber and activated by the rod to issue gas into the second chamber; a controller provided in the gun body associated with the first chamber and the tunnel, wherein the controller has a guiding channel to be manipulative for communication the first chamber and the tunnel and an exhausting channel to be manipulative for communication with the tunnel, whereby the trigger assembly is manipulative to issue the gas in the first chamber to the second chamber for movement the shaft and to exhaust the gas in the tunnel after moving the shaft out.
