ABSTRACT:
Device for electrochemical treatment of workpieces includes a change-over means for actuating the delivery of the workpiece of an electrolyte or a washing medium and their discharge after the workpiece is treated. This change-over means consists of a distribution valve, a control element and a mechanism for separating the discharge of the electrolyte and the washing medium. The distribution valve is located at the junction of separate conduits for the electrolyte and washing medium and operatively connected with the control element so that the distribution valve shuts off alternately the conduit for the electrolyte or the conduit for the washing medium. The mechanism for separating the discharge of the electrolyte and the washing medium is located in an intermediate chamber disposed directly under the working chamber and is operatively connected with the control element through the distribution valve so that the mechanism serves to discharge the electrolyte or the washing medium according to their respective delivery through the distribution valve. This arrangement of the device makes for its simplified construction and more reliable operation.
