Abstract: A high-pressure low-volume spray system includes a hose disposed between a compressor and a spray gun. The hose acts as an accumulator when the spray gun is deactivated. A check valve is disposed in a fitting connecting the hose to the compressor. The check valve includes a spring that applies a nonlinear force to a downstream end of a valve member, such that the valve member tips open in response to the pressure differential, providing a variable flowpath opening through the check valve.

Abstract: The invention includes a spraying device (10) for producing a precise degree of liquid droplet generation on a repeatable basis by combining a specified rate of regulated flow of liquid material with a regulated flow of high-pressure air. The spraying device (10) includes an electric or engine driven direct drive compressor (12). Coupled to the compressor (12) is an air storage tank (14) providing air pulsation reduction to the regulated air and serves as a reservoir for excess airflow generation. A Venturi nozzle (18) is connected to the compressor (12). A liquid supply tube (24) uses a fixed or variable restriction to regulate the liquid flow to the nozzle (18). The vacuum in the liquid supply line (24) draws this liquid flow and mixes the liquid externally with the regulated air in exacting proportions forming specified liquid droplet sizes. The device (10) uses air and liquid regulation combined with a Venturi nozzle (18) and is able to generate extremely consistent liquid droplet sizes.

Abstract: The invention is directed to an improved pneumatic valve for use in paint spray guns of the type having a pneumatic trigger operating mode. When actuated by a trigger, the valve vents a pressurized chamber in the spray gun, causing a piston to move to open air and fluid valves for initiate spraying. The pneumatic valve is in the form of a snap in module which is easily replaced without the need to remove the spray gun from the spray booth and without the need to replace a number of small parts. A small return spring and the pressurized air urge a valve poppet to a closed position. When the trigger is operated, the poppet is unseated to vent the pressurized chamber in the spray gun. The flow of air through the valve during painting prevents dirt and paint overspray from accumulating on the valve.

Abstract: The automatic paint spray gun is for industrial applications involving use with industrial robots. The spray gun comprises a housing including a tubular extension; an air cap mountable onto the tubular extension of the housing; a nozzle disposed within the air cap; and a device for adjusting the flow of air through the housing independent of the air cap. The paint is supplied under pressure to a paint discharge orifice in the nozzle through a first passage. The first passages is essentially centrally disposed within the tubular extension. The atomizing air is supplied to the paint discharge orifice through a second passage to control the atomizing of the paint spray gun. The atomizing air is supplied to the nozzle through a second passage. The second passage is supplied through an annular chamber in the tubular extension, the annual chamber being disposed radially outwardly from the first passage. The fanning air is supplied to the fan discharge openings through a plurality of passages in the tubular extension, the fanning are controlling the fanning of the paint spray. The fanning air is supplied through the plurality of passages disposed radially outwardly from the annular chamber. In addition, the fanning of the paint spray may be regulated independently of the rotative position of the air cap with either turbine air or compressed air.

Abstract: An apparatus for failsafe control of liquid material passage through a line is provided. The apparatus includes a dispensing control unit for coupling to the line, which includes a housing having an inlet, an outlet, and a conduction port extending therebetween for selectively passing the liquid material received from the line therethrough. A control port is disposed in the housing to direct a flow path of at least a portion of a pressurized fluid stream received thereby. A response valve portion also disposed in the housing is reconfigurable between first and second states responsive to the pressurized fluid stream directed thereto, such that in the first state it seals the conduction port against passage of the liquid material, and in the second state opens the conduction port for passage of the liquid material. The response valve portion is resiliently biased to the first state.

Abstract: A sprayer includes first and second syringes that respectively supply first and second liquids, at least one orifice at which the first and second liquids, or a mixture of such liquids, are ejected, and first and second passages through which the first and second liquids are respectively fed toward the nozzle. At least one of the passages is provided with a deformable volume changer adapted to deform to change the internal capacity or volume. A deformer operates to deform the volume changer, and the volume of the volume changer is ultimately allowed to expand so as to have a larger volume in a state in which liquid ejection ceases as compared to during ejection.
