Damping device for a fastening element setting gun

摘要: In a setting gun using explosive force for driving fastening elements into receiving material, an elastic damping device is provided to absorb the residual kinetic energy of piston. The consists plurality serially arranged pairs rings extending between muzzle tube and stop ring mounted in forward end barrel. Each pair radially inner outer each having frusto-conical surface contact with other. surfaces converge firing direction gun. one embodiment, has same axial length, however, another embodiment length increases so that mass direction.
