Abstract: A sprayer attachment for a hand-supported power tool comprises a motion converting mechanism, a pumping mechanism, a spray assembly and a housing. The motion converting mechanism has an input shaft. The pumping mechanism is driven by the motion converting mechanism. The spray assembly is fluidly coupled to the pumping mechanism. The housing assembly couples the motion converting mechanism, the pumping mechanism and the spray assembly. The sprayer attachment may further comprise an anti-rotation bracket extending from the housing. The sprayer attachment may further be coupled to a handheld power tool, such as a cordless drill or a reciprocating saw, with the anti-rotation bracket.

Abstract: A portable airless sprayer comprises a housing, a motor, a pump, a spray tip and a trigger. The motor is mounted to the housing. The pump is mounted to the housing and is driven by the motor. The spray tip assembly receives pressurized fluid from the pump. The trigger is configured to actuate the spray tip assembly and activate the motor. A method of operating a portable airless sprayer comprises moving a lever over a stroke, displacing a valve pin, and activating a motor. The valve pin is displaced with the lever to actuate a spray valve. The motor is activated with the lever to drive a pump that provides fluid to the spray valve.
