    Abstract: A manual check valve for use when priming a fluid supply for a spray gun includes an orifice that opens from the fluid supply into a storage chamber, the storage chamber captures any fluid that is expelled from the fluid supply during priming, and the storage chamber is sealed with a closure. Sealing the storage chamber traps any expelled fluid in the storage chamber and prevents any of the expelled fluid from leaking onto another surface, which keeps the priming operation clean.

    Abstract: A pump draws fluid from a reservoir and drives the fluid downstream to a spray tip where the fluid is applied to a surface. A piston is driven in a reciprocating manner to pump the fluid. A check valve is disposed downstream of the piston to regulate a flow of the fluid downstream from the piston. The pump is initially dry and is primed with fluid prior to operation. To facilitate priming, the piston is dimensioned to impact the ball and unseat a valve member of the check valve during a priming stroke, thereby ejecting any air from the pump through the check valve. With the air ejected from the pump, a vacuum is formed during a suction stroke of the piston, which draws fluid downstream from the reservoir to prime the pump.

    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.

    Abstract: An airless fluid dispensing device comprises a reciprocating fluid pump, a drive element, a spray tip and an accumulator. The reciprocating fluid pump directly pressurizes a fluid. The drive element supplies power to the pump. The spray tip assembly is configured to receive pressurized fluid from the pump. The accumulator is located to be simultaneously pressurized by the reciprocating fluid pump as the spray tip assembly and configured to provide pressurized fluid to the spray tip assembly when the reciprocating fluid pump is at a changeover position.
