摘要： A check valve comprises a housing, a fluid passage, a seat, a valve member and a stop. The fluid passage extends through the housing. The seat is disposed in the fluid passage. The valve member is positioned in the passage to engage the seat. The stop extends through the housing to engage the valve member. The stop is accessible from outside the housing to adjust a distance the valve member can travel from the seat. In one embodiment, the stop includes a variable stop feature, such as an offset pin or a cam. In another embodiment, the stop includes a pump control valve. In yet another embodiment, the housing includes markings to indicate a position of the stop. The valve member comprises a ball or a poppet in different embodiments.

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.

摘要： A control valve for a fluid dispensing device comprises a valve stem, a valve body, a cap and an adjustment mechanism. The elongate valve stem has a flange. The valve body comprises a valve bore in which the elongate valve stem is configured to translate, and a flow path intersecting the valve bore and into which the valve stem penetrates. The cap is joined to the valve body to receive the valve stem such that the flange is positioned between the valve body and the cap. The adjustment mechanism changes a position of the cap with respect to the valve body to vary a distance between the cap and the flange which adjusts the force, and thereby the pressure at which the valve opens.

摘要： A fluid dispensing device includes an electrostatic discharge protection system. Accumulation and discharge of electrostatic energy created by operation of the device is reduced or prevented by the electrostatic discharge protection system without an earth ground connection. The electrostatic discharge protection system may include a number of features, such as a static wick, non-conductive components that electrically isolate the spray tip of the device, nonconductive isolation barriers, nonconductive fluid reservoir and suction tube components, a nonconductive coating of a control valve component, and a nonconductive spring retainer of the control valve.
