Abstract: A fast-set, plural component, spray applicator includes a stationary mix chamber to eliminate dynamic metal-to-metal high pressure fluid sealing. The stationary mix chamber mixes the plural components before dispensing the mixed components from the spray applicator. The spray applicator includes fluid needles configured to engage and disengage seals to perform the fluid valving. Needles control both fluid and air flow to the stationary mix chamber.

Abstract: A spray applicator is operable in a spray state, during which the applicator emits a plural component material formed within a mix chamber of the spray application, and a purge state, during which the spray applicator emits compressed air from the mix chamber. First and second portions of the purge air are provided to the mix chamber through separate flowpaths and combine within the mix chamber. Only one of the portions of purge air is routed through a dosing chamber to entrain solvent and carry the solvent to the mix chamber. The solvent assists in clearing residue from the mix chamber.

Abstract: A fast-set, plural component, spray applicator (10) includes a stationary mix chamber (48) to eliminate dynamic metal-to-metal high pressure fluid sealing. The stationary mix chamber (48) mixes the plural components before dispensing the mixed components from the spray applicator (10). The spray applicator includes fluid needles (76, 78) configured to engage and disengage seals to perform the fluid valving. Needles (76, 78) control both fluid and air flow to the stationary mix chamber (48).
