ABSTRACT:
This invention relates to a nozzle assembly used to atomize liquids within air, particularly useful for coating die surfaces with die release lubricants. The atomizing nozzle includes an internal poppet valve element which is operated to control the flow of lubricant in response to a control air pressure signal. Blow air is initially transmitted to a pre-atomization area where some air is introduced in the lubricant which is thereafter introduced into the main blow air stream. This pre-atomization function has been found to enable fine atomization at low flow rates of lubricant. The pre-atomization bore further enables the device to be self-cleaning by clearing out the lubricant passage. Fine control over lubricant flow rate is provided by an elliptical shaped orifice which is closed off by the end of the poppet valve element. Apparatus for preventing contaminants from entering the poppet valve chamber and coating the inside of the chamber with lubricant are also provided in the form of a small bleed passage formed by the head of the poppet element.
