Abstract: This invention is a seal assembly for sealing fluid needles, spindles and other movable cylindrical objects where a fluid tight seal is needed between the fluid and non-fluid sides of the movable cylindrical object. The seal includes a packing member with a sharply cut-off tubular end and a stop member with a conical recess, both of which encircle the movable cylindrical object. An unrestrained flow cavity is defined by the packing member and the stop member. Positioned behind the packing member are a spring and washer which axially bias the packing member into the conical recess.

Abstract: An improved HVLP spray gun which operates from an air supply source and an improved nozzle therefor are disclosed. The HVLP gun has a fluid nozzle including a first, integral, laterally extending portion including pressure reduction orifices which are calibrated, relative to a fluid passage in the nozzle, so that the spray gun operates as an HVLP spray gun. The fluid nozzle includes a second laterally extending portion including a surface, against which atomization air impinges after exiting the calibrated pressure reduction orifices, and a plurality of longitudinally extending air distribution holes, wherein atomization air, after passing through the calibrated pressure reduction orifices, is directed radially outwardly in an expansion chamber where the low velocity air is pressure equalized before exiting through the air distribution holes and being directed within the air cap inwardly toward a fluid atomizing annulus. An improved air driven HVLP paint spray gun which is especially lightweight and can be used to spray all types of coating materials including corrosive waterborne paints is also disclosed. A spray gun having a reduced trigger force needed to activate the gun is also disclosed. It is preferred that the leading edge of the fluid tip is doubly tapered so as to introduce the pressurized air directly onto the exiting fluid stream, which produces finer atomization with lower air volume consumption.

Abstract: Electrostatic coating apparatus including apparatus for establishing an electrostatic field for indirectly charging atomized droplets of paint or other coating material discharged from an atomizer. A flexible tube is formed into an annulus and is positioned coaxially with the atomizer. Pins extend through the tube and have short ends which project towards a workpiece to be coated. The tube is formed from an insulating outer layer and a semi-conducting inner layer having a high distributed resistance. The pins extend through the inner layer which is connected through a large resistance to a high voltage power supply. The apparatus is particularly useful for charging electrically conductive and semi-conductive materials delivered to the atomizer from a grounded source.

Abstract: A rotary atomizer including a manifold assembly adapted to be attached to a mechanism for supporting and/or moving the atomizer and an air bearing turbine motor housing assembly releasably secured to the manifold assembly. Sources of pressured fluid for actuating the atomizer and coating fluid are connected to the manifold which has fittings for releasably sealing to apertures in the rear cover of the housing assembly. The opposite end of the housing includes a shaping air cap and a shaping air ring which cooperate to define an annulus for discharging a thin ring of shaping air over the peripheral edge of an atomizer bell to direct fluid particles toward a target. Exhaust air from the turbine motor is vented to the inside of the housing and directed to a chamber behind the atomizer bell to aid in directing the fluid particles. A magnetic speed pickup generates a signal which is coupled through a circuit that electrically isolates high voltage which is applied to the atomizer to electrostatically charge the coating particles.

Abstract: An improved hand held rotary atomizer spray gun is disclosed. The spray gun includes a housing with a depending handle. A paint tube within the housing delivers paint to a rotatable bell atomizer which is mounted adjacent the front of the gun. A turbine assembly includes a turbine rotor which drives a turbine shaft which mounts the bell atomizer. The turbine shaft is supported by a bearing air chamber. A turbine air passageway and a bearing air passageway supply turbine air to the turbine rotor and bearing air to the bearing air chamber. When a trigger is squeezed paint is supplied to the atomizer bell while turbine air rotates the turbine shaft and the bell atomizer. An air shuttle assembly prevents air flow to the turbine unless sufficient bearing air is flowing to the bearing air chamber. In a preferred embodiment shaping air is supplied to shaping air openings in a housing air cap and the atomizer bell includes serrations on its inner edge. The shaping air directs the atomized paint particles toward the target. A supplemental crossover passageway provides shaping air to the turbine to maintain proper turbine speed during initial delivery of paint to the atomizing bell. In another embodiment, a high voltage ladder is mounted within the handle and its outlet internally charges the paint to a high voltage. In this embodiment electrostatic forces and mechanical forces are used to atomize the paint particles.

Abstract: The rotary atomizer coater is particularly adaptable to a high voltage rotary atomizer coater which can be robot mounted. A rotatable bell cup, which is mounted on a turbine driven shaft is positioned within a housing. A fluid tube within the housing includes a fluid discharge tip which extends through an inlet opening in the bell cup for supplying charged coating fluid directly to the inner surface of the bell cup interior which is open to atmosphere. An electrical resistor is mounted between the fluid discharge tip and a power supply within the housing. When a grounded object approaches the bell cup, the current between the bell cup and the grounded object will increase and voltage drop across the resistor results, thereby reducing the voltage at the bell cup and diminishing the potential for a high energy spark.

Abstract: An arc preventing electrostatic power supply suitable for operating an electrostatic paint atomizer such as a rotary atomizer. High voltage control is based on the high voltage current, as measured in the ground return path. The power supply is controlled to provide a substantially constant high voltage DC output up to a predetermined current and an output voltage which rapidly drops off as the current increases above the predetermined current. The magnitude of an AC component superimposed on the high voltage DC current is detected to determine incipient arcing. Upon detecting an incipient arcing condition, the output voltage is interrupted for a predetermined short time. When the output voltage is turned back on, it is ramped up from a low level back to the normal high voltage level. While the output voltage is less than a predetermined low level, the sensitivity of the incipient arc detection circuit is increased. The output voltage is again interrupted for the predetermined short time whenever an incipient arcing event is detected.
