ABSTRACT:
The present invention proposes a vacuum/high pressure filling apparatus which can improve the filling rate and shorten the impregnating time period in immersing a porous workpiece into a filling liquid. The vacuum/high pressure filling apparatus includes: an openable and closable hermetic partition chamber unit constituted by two upper and lower split partition wall unit portions, a partition chamber unit opening and closing mechanism to open and close the partition chamber unit, a vacuum suction opening and a pressurizing opening provided for the partition chamber unit, a liquid vessel arranged in the partition chamber unit to receive a filling liquid, a holder arranged, in the partition chamber unit, for the porous workpiece, an elevator unit to move the filling liquid in the liquid vessel and the porous workpiece relative to each other inside the partition chamber unit so as to immerse the porous workpiece into the filling liquid in the liquid vessel and pull up the workpiece from the filling liquid. When the partition chamber unit opening and closing mechanism brings the two upper and lower split partition wall unit portions into hermetic contact with each other, the partition chamber unit is closed and sealed. When the partition chamber opening and closing mechanism spaces the two upper and lower split partition wall unit portions from each other, the partition chamber unit is opened. By using the vacuum/high pressure filling apparatus according to the present invention, composite materials such as lubricant-impregnated metals, thermosetting resin-impregnated cast metals, etc. can be obtained.
