Abstract: A nozzle that produces an outlet velocity air, or other fluid jet, is provided with safety passages which achieve the safety requirement of automatically reducing the local exit pressure “dead end” limit to 30 psig or less when the nozzle outlet is partially or completely obstructed. The safety passages do not reduce the effectiveness of the normal function of the air, or other fluid, jet through the provision of a check valve to block undesirable reverse flow in the safety passage(s) thus avoiding ambient fluid flow to the nozzle exit that degrades the nozzle's normal operating air, or other fluid, jet. This is especially useful for supersonic air gun nozzles which have been adapted to digging in the ground, and other purposes, but it is also useful for sonic and subsonic nozzles that are used for other purposes such as cleaning, and other applications.
