Claim 1
Independent Claim
176 words
A FLUID DRIVE FOR A CONTROL ROD OF A REACTOR CONTAINING A PRESSURIZED FLUID COMRPISING A VERTICAL SYLINDER, A PISTON SLIDABLY MOUNTED IN SAID CYLINDED, A PRESSURE TRANSMITTING CONNECTION BETWEEN THE REACTOR AND THE CYLINDER ABOVE SAID PISTON, A CONNECTING ROD OPERATIVELY CONNECTING SAID PISTON TO THE CONTROL ROD, THE WEIGHT OF SAID PISTON AND PISTON ROD AND THE PRESSURE ON TOP OF SAID PISTON AND PISTON ROD AND THE PRESSURE ON TOP OF SAID PISTON URGING SAID PISTON DOWNWARDLY TOWARD THE LOWER END OF SAID CYLINDER, A SOURCE OF THE PRESSURIZED FLUID UNDER A HIGHER PRESSURE THAN THE REACTOR PRESSURE, A RESTRICTED PASSAGEWAY FROM SAID SOURCE TO THE INTERIOR OF SAID CYLINDER BETWEEN SAID PISTON AND THE LOWER END OF SAID CYLINDER WHEREBY THE PRESSURE FLUID URGES SAID PISTON UPWARDLY TOWARD THE UPPER END OF SAID CYLINDER, A PASSAGEWAY THROUGH THE PISTON AND A VALVE IN THE PASSAGEWAY FOR CONTROLLING THE FLOW OF PRESSURE FLUID THERETHROUGH TO THEREBY CONTROL THE PRESSURE OF THE FLUID BELOW THE PISTON AND ACCORDINGLY THE FORCE URGING SAID PISTON UPWARDLY.
