Patent ID: 7306462

Claim:
An isolated weapon simulator having a bolt providing recoil for a user when said weapon simulator is fired, said weapon simulator comprising: a housing including a piston chamber and a piston positioned in said chamber, said piston connected to the bolt; a regulated gas supply detachably attached to said housing; a valve chamber in said housing in communication with said regulated gas supply and the bolt; a recoil valve positioned in said valve chamber for producing recoil, said recoil valve including a first gate, a second gate, a third gate, and a fourth gate, with a distal valve cavity defined between said first gate and said second gate, a central valve cavity defined between said second gate and said third gate, and a proximal valve cavity defined between said third gate and said fourth gate, said proximal valve cavity being connected with said regulated gas supply while said simulated weapon is not being fired, said recoil valve positioned to control the release of gas from said regulated gas supply to said piston chamber; a pilot valve connected to said regulated gas supply; a pilot channel connecting said pilot valve to said valve chamber, wherein said pilot valve transmits gas to said distal end of said recoil valve from said gas supply to shift said recoil valve in said valve chamber; triggering means for generating an electrical firing signal corresponding to said weapon simulator being fired, said electrical firing signal being transmitted to said pilot valve to open said pilot valve and transmit gas from said regulated gas supply into said pilot channel.
