Abstract: A rotary electrostatic atomizer uses shaping air and pattern control air. Shaping airflow is supplied from shaping air holes aligned along outer one of concentric circles that are concentric with the rotation axis of the bell cup and located behind the front end of the bell cup. Pattern control airflow is supplied from pattern control air holes aligned along inner one of the concentric circles. Both the shaping air flow and the pattern control airflow are expelled in circumferentially twisted directions substantially with an equal twist angle opposite from the rotating direction of the bell cup. The shaping airflow passes a circular line near to and radially outwardly apart from the outer perimeter of the bell cup. The pattern control airflow intersects the shaping airflow from radially inside at the position near to and radially outwardly apart from the outer perimeter of the bell cup.

Abstract: A rotary atomizing head type coating machine which is capable of washing deposited paint from fore end portions of outer peripheral surface of a bell cup. Thinner passages are provided on the bell cup to communicate a paint reservoir with the outer peripheral surface of the bell cup. Thinner which flows out onto the outer peripheral surface of the bell cup through the thinner passages is guided toward the marginal releasing edge of the bell cup. To this end, assist air is spurted out through assist air outlet holes which are provided in the fore end face of a shaping air ring at positions radially on the inner side of shaping air outlet holes. Accordingly, at the time of a washing operation, the thinner which has come out onto the outer peripheral surface of the bell cup is forcibly pushed on the outer peripheral surface by the actions of assist air and shaping air as the thinner is guided toward the fore end of the bell cup to wash away deposited paint therefrom.

In invention may be used in either power spray coating apparatus or liquid spray coating apparatus.

Abstract: A rotary atomizing electrostatic coating apparatus includes air feed passages connected to an air bearing, a turbine, and a shaping air cap, respectively. In any one of air feed passages, a divergence portion for causing a portion of air flowing in the one air feed passage to diverge from the one air feed passage is formed so that a diverging air flows into an interior of the drive shaft. As a result, it is not necessary to provide an additional, air feed passage and an air source therefor for preventing paint from entering a bearing clearance between the drive shaft and the air motor. As a result, a size of the apparatus will not be large and a cost of the apparatus will not substantially increase.

Abstract: Spraying unit for spray coating articles with powdered or liquid material contains a spray head fastened to a front end of a tubular inner and axially extending support and an outer protective tube disposed concentrically about the inner support. The inner support and the outer protective tube are electrically insulative. One or more high-voltage generators are spacedly disposed about the inner support, axially rearward of the spray head, and within an elevated pressure chamber defined between the protective tube and the inner support. The arrangement is such that it produces a constant outwardly bound flow of gas from the elevated pressure chamber which flow prevents soilage of the internal parts by coating material.

Abstract: A conical sheath of air emitted from a vortex plenum adjacent the outer edge of a rotating bell spray apparatus is effective to optionally help atomize the coating material, and to carry the atomized material forwardly toward a confluence on the axis of the rotating head where tubulent mixing of the particles occurs, and the particles are sprayed forwardly for deposition in a uniform thickness film of a uniform population mix of particles sizes. Forward air and tangential air components are admitted to the plenum and are independently controlled so that different spray characteristics are obtained, the tangential air providing a swirl moment to the conical air sheath which enlarges the size of the deposited film pattern. The forward velocity determines the atomization ability of the sheath air and the particle velocity in the spray pattern. Electrostatic and non-electrostatic operations are intended.

Abstract: A drainless water cooler or fountain having a gooseneck water dispensing faucet and a waste water receptacle cup mounted on top of the multiply tiered top member. A cup is removably carried within a downwardly depending well which can be retrofitted for readily and economically converting the drainless-type water fountain or cooler into a more permanent drain connected installation. A dual action valve featuring reduced diameter valve seat and valve construction is capable of regulating and dispensing either hot or cold water through the common gooseneck faucet. Placement of the faucet and waste water receptacle cup on the top of the cabinet eliminates the need to bend or stoop when dispensing water or emptying the receptacle cup. The receptacle cup is disposed within the interior of the cabinet and is thus protected against accidental bumping or spilling.
