Gas balancing refrigeration method

Claim 1

IN A METHOD OF GAS BALANCING REFRIGERATION IN WHICH GAS FROM A HIGH PRESSURE SUPPLY SOURCE IS DELIVERED THROUGH VALVE MEANS TO A CONFINED SPACE WHOSE VOLUME IS SEPARATED INTO THREE VARIABLE CHAMBERS BY WALLS MOVABLE UNDER PRESSURE, TWO OF WHICH ARE CONNECTED TO ONE ANOTHER FOR THE FLOW OF GAS THEREBETWEEN, AND SAID VALVE MEANS COMPRISING A MULTIPASSAGE ROTARY INLET AND OUTLET VALVE FOR SEQUENTIALLY CONTROLLING THE FLOW OF FLUID INTO AND RELIEVING THE PRESSURE FROM THE THREE CHAMBERS, THE STEPS WHICH INCLUDE INTRODUCING A QUANTITY OF HIGH PRESSURE GAS BY MOVEMENT OF SAID VALVE TO A FIRST POSITION INTO ONE OF THE CHAMBERS WHILE A SECOND CHAMBER IS INCREASING IN VOLUME, AND A THIRD CHAMBER CONNECTED TO THE SECOND CHAMBER IS DECREASING IN VOLUME, THEN SUPPLYING HIGH PRESSURE GAS BY MOVEMENT OF SAID VALVE TO A SECOND POSITION TO THE SECOND CHAMBER IN BALANCED RELATIONSHIP TO THE FIRST AND THRID CHAMBERS, RELEASING PRESSURE IN THE FIRST CHAMBER BY MOVEMENT OF SAID VALVE TO A THIRD POSITION WHILE MAINTAINING HIGH PRESSURE OF GAS IN SECOND CHAMBER, CONDUCTING HIGH PRESSURE GAS FROM THE SUPPLY SOURCE AND FROM THE SECOND CHAMBER THROUGH A REGENERATIVE PATH OF TRAVEL IN WHICH HEAT IS REMOVED AND STORED, AND THEN TO A THIRD CHAMBER, THEN RELIEVING PRESSURE IN THE THIRD CHAMBER BY MOVEMENT OF SAID VALVE TO ITS STARTING POSITION TO CAUSE EXPANSION OF THE GAS DELIVERED WHEREBY USEFUL COOLING IS PRODUCED AND THEN RETURNING THE EXPANDED GAS ALONG THE SAID PATH OF TRAVEL AND REPEATING THE GAS DELIVERY CYCLE.
