摘要： A handheld airless fluid dispensing device comprises a pump (18), a drive element (20) and an orifice element (14). The pump directly pressurizes a fluid. The drive element supplies power to the pump. The orifice element is connected to the pump and atomizes un-thinned architectural coating to a particle size of no greater than approximately 150 microns. The pump generates orifice pressures up to approximately 2.48 MPa and the orifice has an area of approximately 18.7 mm 2 . The pump, drive element and orifice element are integrated into a handheld housing (12) whereby the pump comprises a reciprocating piston fluid pump comprising at least two pumping chambers (266, 268) configured to be actuated out of phase by at least one piston. In another embodiment, the reciprocating piston fluid pump comprises two pistons having different displacements that are linearly actuated by a wobble assembly driven by a gear reducer and an electric motor.
