Air pressurized actuated atomizer

Claim 1

A mould cleaning and lubricating device comprising in combination a support body, a lubricating liquid feed duct, a pressurized air feed duct, said ducts being both connected to the support body, a first delivery valve for the pressurized air feed duct and a second delivery valve for the lubricating liquid feed duct, a single control lever pivotally mounted on the support body, and actuating in a depressed position both said first and second valves, an atomizing nozzle mounted at the end of the pressurized air feed duct, a connector body connecting the adjacent ends of the pressurized air duct and the lubricating liquid duct, said connector body having a decompression chamber, an atomizing head removably connected to the said connector body and fed through the said decompression chamber, a needle valve formed with a head projecting from the connector body for manual actuation from the outside to control the passage of lubricating liquid between the end of the liquid feed duct and the said decompression chamber, by greater or lesser physical obstruction thereof, whereby the atomizing head may be fed with pressurized air only and with variable liquid rate in dependence of the adjustment of the said needle valve, said connector body having a hollow portion constituted by a conically tapered section extending in narrowIng fashion from the inlet for lubricating liquid towards said decompression chamber, and a cylindrical section smoothly merging with the conically tapered section in continuation thereof and opening directly into the decompression chamber adjacent the atomizing nozzle, the needle valve including a frustum cone shaped terminal portion cooperating with said hollow portion formed in said connector body, the longitudinal axis of the hollow portion and the axis of the atomizing nozzle being perpendicular to one another.
