Abstract: A rotary type electrostatic spray painting device comprising a rotary shaft and a spray head fixed onto the front end of the rotary shaft. Paint is fed onto the cup-shaped inner wall of the spray head. The rotary shaft is supported by a single thrust air bearing and a pair of radial air bearings. An electrode, continuously contacting the rear end of the rotary shaft, is provided. A negative high voltage is applied to the housing of the painting device. In addition, the negative high voltage is also applied to the spray head via the electrode and the rotary shaft.

Abstract: A powder spray gun includes a rotary distributor (39) which is capable of operating at slower speeds than liquid spray gun to reduce the problem of powder fusing, increases bearing life, reduces wear on moving parts. The powder spray gun has a powder flow path which extends through a gun body to a powder outlet. A drive mechanism in the form of a pneumatic motor (22) is located within the housing and connected to the distributor to rotate the distributor. The powder thus enters a passageway in the rotating spindle before it passes into the rotating distributor. A non-rotating flow tube (49) through which powder flows into the passageway in the spindle, with a gap (51) being formed between the non-rotating flow tube and the rotatable spindle. The gap communicates with the chamber whereby pressurized air from a pressurized air chamber escapes through the gap to provide a rotary seal between the tube and the spindle.

Abstract: An electrode (60) for electrically charging dispensed coating material is electrically substantially isolated from the coating material dispensing device (16). Sources provide first (30-36) and second (70-76) coating materials, the first (30-36) of which is electrically substantially more conductive and the second (70-76) of which is electrically substantially less conductive. The first (30-36) or the second (70-76) coating material is alternately supplied to the coating material dispensing device (16). A high-magnitude electrostatic potential supply (58) provides electrostatic high potential to the electrode (60) and selectively to the coating material dispensing device (16). The high-magnitude electrostatic potential supply (58) is coupled (62) to the coating material dispensing device (16) when the second coating material (70-76) is supplied to the coating material dispensing device (16) and is uncoupled (62) from the coating material dispensing device (16) when the first coating material (30-36) is supplied to the coating material dispensing device (16).

Abstract: An electrostatic spray device (10) having a gun barrel (28, 38) formed with a powder delivery passageway (32, 46) connected to a source of particulate powder material, a nozzle (48) mounted at the forward end of the gun barrel which is formed with a discharge opening (52) for emitting coating particles, a deflector (88) carrying an electrode (90) which produces an electrostatic field in the path of the coating particles emitted from the discharge opening (52) and a pattern adjustment sleeve (54) carried by the gun barrel (28, 38) which is radially outwardly spaced from the deflector (88) and discharge opening (52). Both the deflector (88) and pattern adjustment sleeve (54) are axially movable relative to one another, and relative to the discharge opening (52), to vary the width of the spray pattern of coating particle emitted from the discharge opening (52) while controlling the concentration of the electrostatic field produced by the electrode (90).

Abstract: Spray coating device with a rotary spray organ for cleaning, a cleaning fluid (solution) is sprayed by the rotary spray organ (4). Created thereby within the sprayed cleaning fluid is an area of vacuum, injected into it through the sprayed cleaning fluid is air which entrains particles of the cleaning fluid and is drawn in the form of a gas/cleaning fluid mixture by the vacuum on the front (28) of the rotary spray organ (4), cleaning there also its center.

Abstract: A device of this sort is fitted with a rotating atomizer bell (10) revolving around an axis (16), the bell (10) having a central opening (14) for the admission of colour and a transitional surface (26) with a radial component for colour distribution on the edge of the bell (20); as well as a coaxial deflection component (28) mounted in the bell which, together with the bell, forms a gap-like intermediate chamber (32), so as to ensure that, in particulr, metal pigment agglomerates of a metal-base laquer, or other pigment segregation elements from the colour to be atomized and flowing through the chamber (32) do not become ingrained, or conversely, are not washed out, it is proposed that the reverse side of the surface (29) of the detection component (28) outside of its center, located opposite the bell opening (14), and/or the part (26.1.) of the transition surface (26) of the bell (10) which lies axially opposite this surface (29) be provided with local anomalies of gap width (70, 72) distributed over the surface radii and the circumference of the axis (16).

Abstract: A rotary atomizer spray painting device (10) having a nonconductive fixed, axial tube (20) for feeding paint, and having a nonconductive rotor (17) supported for rotation in a nonconductive housing (12) about the tube on air bearings or nonconductive ball bearings, and having turbine drive blades proximate one end thereof, the rotable rotor (17) supported inside of a nonconductive housing (12) which has a high voltage electrical path therethrough, electrically connected to one or more symmetrically spaced forwardly projecting needle electrodes (50), the rotable rotor being fixedly attached to a nonconductive forwardly projecting bell-shaped atomizer (14), the housing having pressurized air opening (38) for directing air in driving relationship to the turbine blades. The nonconductive design eliminates the danger of the atomizer picking up and storing high amounts of electrical energy, which poses a danger when such charged components inadvertently contact people or nearby objects.
