Load applying device for a pressure test chamber

Abstract

Abstract A DEVICE FOR APPLYING A LOAD TO A SAMPLE WITHIN A PRESSURE TEST CHAMBER EMPLOYING AN OUTER HOLLOW CYLINDRICAL LOAD SLEEVE SEALED BY AN O-RING IN A CHAMBER ENTRANCE. AN INNER LOAD ROD SLIDES IN THE OUTER LOAD SLEEVE IN LONGITUDINALLY RECIRCULATING BALL BUSHINGS TO MOVE WITH A MINIMUM OF FRICTION AND IS CONNECTED TO THE END OF THE LOAD SLEEVE THROUGH A BELLOWS ASSEMBLY ATTACHED BOTH TO THE END OF THE INNER LOAD ROD AND TO THE OUTER LOAD SLEEVE. THE INNER LOAD ROD ENGAGES THE SAMPLE WITHIN THE PRESSURE CHAMBER AND THE LOAD PRESSURE IS MEASURED BY THAT APPLIED TO THE INNER ROD INDEPENDENTLY OF ANY LOAD WHICH MAY BE APPLIED TO THE LOAD SLEEVE. THE EFFECT OF THE CHAMBER PRESSURE ON THE INNER LOAD ROD MAY BE ZEROED OUT OF A READ-OUT OR RECORDING DEVICE OR MAY BE READILY COMPUTED FROM THE VALUE OF THE CHAMBER PRESSURE AND DEDUCTED FROM THE TOTAL LOAD ON THE INNER ROD TO GIVE THE ACTUAL LOAD APPLIED TO THE SAMPLE IN THE CHAMBER.
