HIGH-PRESSURE DEVICE FOR CLOSING A CONTAINER IN A CLEAN ROOM

摘要

THE INVENTION RELATES TO A VERY COMPACT DEVICE AND A PROCESS FOR OPERATING CLOSURES OF VESSELS BY MEANS OF ROTATION-SYMMETRIC RECIPROCATING PISTON MECHANISM COMBINED WITH A GUIDE CYLINDER(4) AND MAINLY OPERATED BY A MEDIUM SIMULTANEOUSLY USED AS PROCESS FLUID IN THE PRESSURE VESSEL.THE UPPER FACE OF THE HYDRAULIC PISTON(1) AT LEAST FORMS A PART OF THE VESSEL CLOSURE OR IT IS PROVIDED WITH A RIGID LINK TO SAID CLOSURE. THE IDEAL MEDIUM USED TO DRIVE THE HYDRAULIC PISTON(1) AND TO CARRY OUT OF THE PROCESS IS A SUPERCRITICAL FLUID.FIGURE 1
