Abstract: A plural component flushless spray gun has a fluid outlet orifice defined by two opposed inlet orifices with a thin blade interposed therebetween. The blade prevents fluidic material exiting each inlet orifice from flowing directly into the other, and is slotted at its forward end to define a very small volume chamber into which the components flow for mixing prior to being emitted through the outlet orifice defined at the forward end of the slot. Because the chamber has a very small volume, the components are intimately mixed for better polymerization, and only a very small quantity of reactive components are mixed within the gun immediately behind the outlet orifice. Consequently, should the mixed components harden within the gun, only a limited amount of material is involved and the blockage may readily be removed simply by triggering the gun on to eject the blockage through the outlet orifice.
