Abstract
A CO,jet spray nozzle comprising multiple nozzle orifices for use in producing CO,jet spray. The nozzle comprises a body, an elongated nozzle tube extending from the body having an axial hole therein, and an orifice disk disposed at the base of the nozzle tube in the axial hole. The orifice disk contains a plurality of orifices disposed therein that form a critical orifice and that is an integral part of the nozzle. The orifices may be drilled by means of a laser beam or electron discharge machining through the orifice disk. The orifice disk and nozzle tube are typically welded together to prevent leakage. By fabricating different nozzles in which the orifice size, orifice geometry (round, oval, or elongated slit), total orifice area, nozzle diameter and nozzle length is varied within a well defined matrix, any intensity of CO,jet spray may be obtained. By varying the arrangement of the orifices, nozzle geometry, and nozzle length, different spray patterns may be provided. Both circular and linear orifice patterns are disclosed that provide circular and elongated spray patterns. The linear jet spray nozzle may contain multiple orifices with different dimensions or a changing density of orifices.
