Abstract: A fluid sprayer comprises a fluid source, a spray tip, a pump, and an outlet check valve assembly. The spray tip has a fluid outlet aperture, and the pump is disposed to pump fluid from the fluid source out the fluid outlet aperture. The outlet check valve is disposed between the pump and the spray tip, and includes a sealing element, a seat, and a polymer housing. The seat is aligned to receive the sealing element, and the polymer housing is overmolded about the seat.

Abstract: A fluid dispensing device comprises a housing body, a reciprocating piston fluid pump, a primary drive element, a wobble assembly and a spray tip. The reciprocating piston fluid pump has a piston disposed within a pumping chamber inside the housing body. The primary drive element is coupled to the housing body to provide a rotary input. The wobble assembly connects the primary drive element to the reciprocating piston fluid pump to convert the rotary input into reciprocating input to the piston. The spray tip connects to an outlet of the pumping chamber.

Abstract: A handheld airless fluid dispensing device comprises a pump, a drive element and an orifice element. 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 mm2. In one embodiment, the pump, drive element and orifice element are integrated into a handheld housing. In one embodiment, the pump comprises a reciprocating piston fluid pump comprising at least two pumping chambers 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.

Abstract: A fluid sprayer includes a pump motor, a piston, a pump housing, and an outer housing. The piston is reciprocatable by the pump motor. The pump housing comprises a pump chamber housing disposed to receive the piston, and a plurality of alignment pins extending laterally away from the pump chamber housing. The outer housing surround and anchors the pump motor, and has a plurality of internal lateral bores disposed to slideably receive and retain the alignment pins, such that the pump housing is free to self-align with the piston.
