Abstract
A spray assembly including an improved control valve is disclosed which is designed for heavy industrial usage to enable application of air and/or atomized liquids to be applied to the working surfaces of various types of forming apparatus such as molds and dies for example. The control valve utilized in the spray assembly of the present invention incorporates a piston actuated plunger assembly which is designed for extremely rapid operation whereby substantially maximum liquid fluid flow may be obtained almost instantaneously. Additionally, the spray assembly is designed so as to enable application of either one fluid alone such as blow air or both air and liquid. Also, the plunger is positioned so as to provide substantially unobstructed liquid flow into the air stream for atomization when in a fully open position thereby enabling large volumes of liquid to be applied within relatively short cycling time. An adjustable stop is also provided so as to allow modulation of the liquid flow should this be desired. Only a single moving valve member is required which is controlled by pressurized air so as to provide extremely rapid on/off cycling thereby assuring long dependable operation as well as enabling relatively rapid repair.
