    Abstract: A spray tip is configured to atomize thick, viscous fluids. The spray tip includes a pre-orifice piece having an inlet orifice that defines a first restriction in a fluid path through the spray tip. The spray tip also includes a tip piece having an outlet orifice that defines a second restriction in the fluid path. The first and second restrictions are the portions of the fluid path having the smallest flow areas. A cross-sectional area of the outlet orifice is greater than a cross-sectional area of the inlet orifice.

    Abstract: A fluid cartridge for a plural component sprayer is configured to receive first and second component materials and purge air from the sprayer and provide the first and second component materials and purge air to a mix chamber for spraying. The fluid cartridge includes a cartridge body, material flowpaths extending from a second end to a cartridge bore, and a purge path extending from the second end to the cartridge bore. Fluid checks are disposed in the material flowpaths and purge path to prevent backflow out of the fluid cartridge. Side seals are disposed in the material paths and are pre-loaded to extend into the cartridge bore and engage a mix chamber within the cartridge bore.

    Abstract: A tip piece for a sprayer includes a tip body extending between a first end and a second end. A passage extends inside the tip body from the first end to a terminal end between the first end and the second end of the tip body. A nozzle extends into the tip body from the second end of the tip body and intersects the terminal end of the passage to form an orifice. A rounded interface is formed on a perimeter of the orifice between the nozzle and the terminal end of the passage.
