Compressed gas gun having reduced breakaway-friction and high pressure dynamic separable seal and flow control and valving device

Abstract

A reduced breakaway-friction flow control and valving device for a compressed gas-powered projectile accelerator is disclosed having an improved means of reducing break-away friction, an improved sealing arrangement, and self-contained modular components to improve efficiency, manufacturability, and reduce size and weight.

         15 . A flow control and valving device for a compressed gas projectile accelerator comprising:
 a housing having a forward end and a rear end;   a breech formed within the housing in which a bolt is located that is moveable from a forward position to a rearward position, the bolt having a gas passage therethrough;   a gas source passage formed within the housing for communicating compressed gas from a compressed gas source;   a valve passage formed within the housing in communication with the gas source passage, at least one lower gas feed passage, and at least one rear passage located within the housing;   a gas distribution passage in communication with the breech via an upper gas feed passage, and in communication with the valve passage via the at least one lower gas feed passage;   a valve slider having a forward end and a rear end selectively moveable from a forward position to a rearward position within the valve passage, the valve slider having at least one annular groove formed on an outer surface thereof, being located in the at least one annular groove;   wherein the selective movement of the valve slider selectively controls the flow of compressed gas between the valve passage, the lower gas feed passage, and the at least on rear passage.   
     
     
         16 . A flow control and valving device for a compressed gas projectile accelerator comprising:
 a housing having a forward end and a rear end;   a breech formed within the housing in which a bolt is located that is moveable from a forward position to a rearward position, the bolt having a gas passage therethrough;   a gas source passage formed within the housing for communicating compressed gas from a compressed gas source;   a valve passage formed within the housing in communication with the gas source passage, and at least one gas outlet;   a coil surrounding a portion of the valve passage, the coil adapted to be selectively magnetized upon actuation;   a magnetic valve slider having a forward end and a rear end selectively moveable from a forward position to a rearward position within the valve passage upon actuation of the electromagnetic coil;   wherein the selective movement of the valve slider selectively controls the flow of compressed gas to at least one gas outlet.   
     
     
         17 . A flow control and valving device for a compressed gas gun comprising:
 a housing having a forward end and a rear end;   a breech formed within the housing;   a bolt located in the breech moveable from a forward position to a rearward position, the bolt having a gas passage therethrough;   a gas source passage formed within the housing for communicating compressed gas from a compressed gas source;   a valve passage formed within the housing in communication with the gas source passage;   a valve slider having a forward end and a rear end selectively moveable from a forward position to a rearward position within the valve passage, the valve slider having at least one annular groove formed on a surface thereof;   a first floating seal positioned in the annular groove of the valve slider, the first floating seal being a smaller dimension than the annular groove;   wherein selective movement of the valve slider controls the flow of compressed gas between the valve passage and the breech.
