Abstract:
1. An electro-pneumatically operated paint ball gun, said paint ball gun having a main body defining a first bore for receiving a paint ball, said first bore also receiving a reciprocable bolt assembly which in respective first and second positions relative to said main body closes and opens a breech of said gun, a feed inlet opening to the first bore for providing a supply of paint balls to said breech, said main body further defining a second bore spaced below and substantially parallel with said first bore, and a passage for communicating pressurized gas from said second bore to said breech; a pneumatic discharge valve disposed in said second bore, said pneumatic discharge valve including a seat member, and a poppet valve member sealingly engaging in a first position upon said seat member to close communication of pressurized gas from a source thereof to said breech via said passage, said poppet valve member including a poppet valve stem extending through said seat member rearwardly of said gun; a pneumatic hammer assembly also disposed in said second bore aft of said discharge valve, said pneumatic hammer assembly including a sleeve member defining a bore, a hammer member reciprocally and sealingly movable in said sleeve member bore and cooperating there with to define a variable volume chamber having a minimum volume with said hammer member in a first position, a spring disposed in said second bore between said pneumatic hammer assembly and said pneumatic discharge valve and biasing said hammer member to said first position, said hammer member in response to receipt of pressurized gas in said sleeve bore being movable axially forwardly of said gun to a second position to abut said poppet valve stem, thus unseating said poppet valve member to a second position and opening said discharge valve to communicate pressurized gas to said breech via said passage.
