Abstract: A fluid dispensing device comprises a housing body, a fluid container, a reciprocating piston fluid pump, a primary drive element and a spray tip. The housing body is configured to be carried and supported by an operator of the hand held airless fluid dispensing device during operation. The fluid container is supported by the housing body. The reciprocating piston fluid pump is coupled to the housing body and comprises at least two pumping chambers configured to be actuated out of phase by at least one piston. The primary drive element is coupled to the housing body and connected to the reciprocating piston fluid pump to actuate the at least one piston. The spray tip is connected to an outlet of at least one of the pumping chambers.

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.
