ABSTRACT:
Apparatus for treating cup-shaped workpieces in which the workpieces are positioned within a shape-conforming chamber formed with an outlet port in the base thereof and a conforming nozzle is positioned within the interior of the workpiece in close clearance-spaced relationship. The nozzle is provided with an axial port for discharging a high-pressure treating fluid against the central portion of the interior bottom surface of the workpiece, causing a high-speed radial outward flow therealong and thence axially outwardly along the interior wall surfaces of the workpiece. Upon reaching the open end of the workpiece, the direction of flow is reversed and is directed axially along the exterior wall surface of the workpiece, and upon passing the bottom edge thereof, the fluid is deflected in impinging relationship against the outer bottom surface, whereafter it is discharged through the outlet port and is recovered for reuse. The apparatus further include mechanism for discharging a plurality of individual treating fluids in sequentially-phased relationship separated by intervening purging abstract so as to effect a plural treatment of the surfaces of cup-shaped workpieces.
