be used in the suppressed configuration as it will not prevent flash without the rest of the suppressor immediately following the mixer nozzle 1002 is an expansion chamber 1004 in order to allow the gaseous flow to separate into multiple paths it is necessary to allow the flow to expand away from the centerline 1005 i e the longitudinal axis of the suppressor since the flow has axial momentum in the same direction as the projectile e g bullet not shown it will tend to remain close to the centerline the mixer nozzle 1002 and the expansion chamber 1004 are designed to generate ejector action that accelerates outward expansion of the muzzle gases in order for the muzzle gases to rapidly mix with the chamber gases and then have a viable alternate flow path to the exit at this point the core of this design is introduced after the flow has expanded to fill the expansion chamber 1004 the first obstacle is introduced a generally u201c wagon wheel u201d shaped blast baffle 1006 its purpose is to immediately disrupt the mixer nozzle exit flow without creating excessive amounts of back pressure its secondary purpose is to encourage the gas to not flow along the centerline 1005 both of these.
