Spray element especially for mold sprayers

摘要

A spray element for use with a mold sprayer of the type used to spray a mold prior to or between cycles of a manufacturing operation such as die-casting, drop forging or other operations involving the working of metals. The spray element includes a valve body having an internal elastic pretension. The valve body may be positioned in either an open or closed position in relation to a valve seat. A control pressure is applied, through a separate feed line, to the valve body to open and close the valve by forcing the valve body against or away from the valve seat. The spray element also includes a feed line supplying working air which cooperates with an atomizer attached to a feed line supplying a working medium to the atomizer to atomize the working medium when the valve body is actuated.
