Abstract: 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.
Abstract translation: 移动喷雾分配器包括流体循环系统和加热单元。 流体循环系统具有能够以高压喷射模式和低压再循环模式从流体容器循环流体并将流体提供给喷雾器的电动泵。 电动泵在低压再循环模式下比在高压喷射模式下降低功率。 加热单元设置在流体循环系统内以将流体加热到目标温度，并且包括初级加热器和升压加热器。 主加热器被配置为在高压喷射模式和低压再循环模式期间都是有效的。 升压加热器与主加热器流体串联，并且仅在低压再循环模式下被配置为有效。

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 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.
