ABSTRACT:
An apparatus for washing automotive, aviation, marine and general parts with a volatile solvent during maintenance, repair and rebuilding operations. The apparatus includes a wash basin with a drain to facilitate return of the solvent to a holding tank having a pump therein for recirculating the solvent back to the wash basin through a discharge spout for washing parts. A first valve assembly between the drain and holding tank closes during periods of non-use to prevent vapors from escaping to the atmosphere. During a timed recycling process, a second valve assembly releases used, contaminated solvent from the holding tank into a distillation pot where the solvent is heated under vacuum to produce vapors. The vapors pass through a condenser where they are cooled to a liquid state, yielding pure solvent, which is directed into the holding tank for future parts washing as demanded.
