Abstract
Method of solvent spray impact cleaning utilizing a hand directed pump nozzle for impact spraying of parts, by eye through a viewing window, and an enclosing chamber containing the parts in a manner whereby the zone for solvent spray by the pump nozzle is closely confined within the enclosure so as not to expose the operator or the outside environment to the liquid runoff of the solvent, or to the sprayed particles thereof, or to solvent steam or vapors rising at the spraying temperature. The internal air of the chamber and all solvent are continually recycled electrically by blower and pump for re-use after the latter, once in an operative status, are then activated according to the washing procedure. The recycled air re-enters through a blower nozzle directed so that it clears the window. Automatically, sensed immediately the chamber is opened to exchange parts, the blower and pump nozzles are disabled from their operative status through internal confinement of the circulated air and liquid by preventing circulation entirely.
