Abstract: A mix chamber for a plural component sprayer is configured to receive first and second component materials and emit a spray of a resulting plural component material. The mix chamber includes a chamber body extending between a first end and a second end and including flat lateral sides. A ramp feature is disposed proximate the first end and is configured to contact and push first and second side seals, respectively, away from a body axis as the mix chamber shifts in a first direction through a cartridge bore to increase a gap between the first side seal and the second side seal such that the first side seal engages the first flat lateral side and the second side seal engages the second flat lateral side.

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 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.
