    摘要： A mobile spray dispenser comprises a fluid circulation system and a heating unit. The fluid circulation system has a motorized pump capable of circulating fluid from a fluid reservoir in a high-pressure spray mode and a low-pressure recirculation mode, and of providing the fluid to a sprayer. The motorized pump draws lower power in the low-pressure recirculation mode than in the high-pressure spray mode. The heating unit is disposed within the fluid circulation system to heat the fluid to a target temperature, and comprises a primary heater and a boost heater. The primary heater is configured to be active during both the high-pressure spray mode and the low-pressure recirculation mode. The boost heater is in fluid series with the primary heater, and is configured to be active only during the low-pressure recirculation mode.

    摘要： 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.

    摘要： 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.
