         8 . The apparatus of  claim 1 , in which the trigger control means operates said main valve to control air flow inside of said combustion chamber. 
     
     
         9 . The apparatus of  claim 1 , in which said trigger control mean includes at least one electronic switch to control a high voltage coil to provide a high voltage to said spark plug to ignite the fuel in said combustion chamber. 
     
     
         10 . An apparatus for launching foam rockets and projectiles previously loaded in muzzle loading grenade shells using a cordless nailer fuel cell and the metering valve provided with, comprising: A main body including a combustion area, a launching area, a fuel cell housing, main valve means controlling the flow of air into said chamber and the exhausting of the gases of combustion from said combustion chamber, a fan-assisted combustion chamber formed within said main body having said main valve as one wall, and said grenade shell or said rocket as another wall, means to provide fuel to said combustion chamber and ignite same for launching the projectile, trigger control means, a fuel cell release lever, trigger with fuel cell injector lever, and a connection means for grenade shells. 
     
     
         11 . The apparatus of  claim 10 , in which the fuel cell housing is attached to said main body, close to said combustion chamber. 
     
     
         12 . The apparatus of  claim 10 , in which said fan-assisted combustion chamber includes at least one fan or at least one rigid or flexible vane and controls therefor to operate same, to create of gas transport, turbulence or change of pressure inside of said chamber. 
     
     
         13 . The apparatus of  claim 10 , in which the main valve means includes a main valve body with inlet ports and a main valve seal that closes off said combustion chamber during combustion and open said ports to permit scavenging of said combustion chamber. 
     
     
         14 . The apparatus of  claim 10 , in which the main valve means includes at least one switch to inform its status. 
     
     
         15 . The apparatus of  claim 10 , in which the means for providing fuel into said combustion chamber includes the cordless nailer fuel cell and said metering valve to introduce a predetermined quantity of fuel into said combustion chamber. 
     
     
         16 . The apparatus of  claim 10 , in which the means to providing fuel into said combustion chamber includes said fuel cell installed in said housing, said metering valve connected to said fuel cell, and said fuel cell release lever surrounding at least part of fuel cell constructed and arranged to move same, said release lever defining a depending portion adapted to be contacted by the fuel injector lever to move said fuel cell and operate said valve to introduce a metered amount of fuel into the combustion chamber. 
     
     
         17 . The apparatus of  claim 10 , in which the trigger control means operates said main valve to control air flow inside of said combustion chamber. 
     
     
         18 . The apparatus of  claim 10 , in which said trigger control mean includes at least one electronic switch to control a high voltage coil to provide a high voltage to said spark plug to ignite the fuel in said combustion chamber.
