摘要：A handheld airless fluid dispensing device comprises a pump (18B), a drive
element (20B) and an orifice element (14B). The pump directly pressurizes a fluid. Thedrive element supplies power to the pump. The orifice element is connected to the pumpand atomizes un-thinned architectural coating to a particle size of no greater thanapproximately 150 microns. The pump generates orifice pressures up to approximately2.48 MPa and the orifice has an area of approximately 18.7 mm2. The pump, driveelement and orifice element are integrated into a handheld housing (12B) whereby thepump comprises a reciprocating piston fluid pump comprising at least two pumpingchambers (266, 268) configured to be actuated out of phase by at least one piston. Inanother embodiment, the reciprocating piston fluid pump comprises two pistons havingdifferent displacements that are linearly actuated by a wobble assembly driven by a gearreducer and an electric motor.
