Abstract: A liquid spray gun whih includes an improved flow rate control. The improved flow rate control results from a valve in the supply inlet line which can restrict the flow of liquid material from the supply container. The ability to vary the flow rate is improved because, while the electromagnetic motor is maintained at maximum electrical input power, inlet flow can be accurately regulated. Maintaining maximum input pressure ensures optimum spray performance. Finer atomization at lower flow rates can be achieved from the improved flow control system.
