Abstract
A barrier means for a parts washer apparatus including a fluid curtain (30, 32) generated at the entrance and exit of the wash zone (12) of the parts washer (10), said fluid curtain defined in a thin planar shape and substantially covering the opening to and exit from said wash zone. The fluid barrier (30, 32) is produced by the flowing of fluid over one or more edges (36, 46) of a reservoir (34) positioned at the top of said wash zone (12), said edge (36, 46) defined such that said fluid flows thereover in a uniform manner. Alternately, said fluid curtain is generated by fluid emanating from a plurality of nozzles (84), each nozzle defined with a fan-shaped opening such that a laminar flow of fluid (83) is generated thereby.
