摘要： A spray gun includes several atomizer and a plurality of conduits communicating therewith for supplying different coating materials. A valve needle is disposed in each supply conduit, such needles being individually controlled by pneumatic cylinders. In one embodiment the supply conduits are oriented at an acute angle relative to the axis of the gun barrel. In a second embodiment the supply conduits curve away from such longitudinal axis, with the valve needles formed of elastic material. In a third embodiment the supply conduits extend parallel to the longitudinal axis of the barrel, with the pneumatic cylinder oriented at a right angle relative to the valve needle and connected thereto by means of a knee joint.

摘要： An electrostatic spray gun includes a housing, a nozzle with a coating material discharge opening, and means for connection to an electric resistor and high voltage cable. An electrode is carried by an electrode extension body so as to be disposed forwardly of the nozzle discharge opening at a distance sufficient to effectively charge spray particles of a coating material having high conductivity. The extension body can be adjustable in position to accommodate an adjustable nozzle, while still making effective electrical contact with the resistor.

摘要： An electrostatic paint spray pistol with a rotary bell shaped atomizer head is provided with a bell rim in the shape of a rounded circular arch from which paint may be centrifuged at various positions. This produces the advantage of being able to control rotating speed and paint throughput over a wide range.High rotating speed of the bell is attained by an air motor in a manner such that the air flow does not interfere with the electrostatic precipitation action of the centrifuged paint.The electric field position on the bell does not need to emanate from the same position at which the paint is centrifuged off the rounded bell rim.
摘要翻译： 具有旋转钟形雾化器头部的静电喷雾手枪设置有圆形圆拱形状的钟形边缘，可以从该圆形圆拱的各个位置离心油漆。 这产生了能够在宽范围内控制旋转速度和涂料生产量的优点。 钟的高转速通过气动马达实现，使得空气流不干扰离心油漆的静电沉淀作用。 钟上的电场位置不需要从与圆形钟形边缘离心的相同位置发出。
