ABSTRACT:
An improved poppet valve seat having a predetermined through-bore restricting orifice operating in conjunction with a fluid diffuser and diffuser flow passages thereof reduce the velocity of fluid ejected from the spray gun below levels which are hazardous for potential injection into the skin of a user or the like when the spray tip and associated safety guards are removed from a spray gun. However, while the velocity of the paint passing through the spray gun is reduced to avoid the injection hazards, the atomization pressures required for cohesive and complete atomization of the fluid passing through the airless paint sprayer is maintained to provide an efficient and effective atomization of the fluid in an airless sprayer.
