Ultra pressure contaminant-free pumping means

Claim 1

AN ULTRA PRESSURE CONTAMINANT-FREE PUMPING MEANS FEATURING ABSENCE OF CONTAMINATION OF FLUID BEING PUMPED BY HYDRAULIC FLUID, COMPRISING: A PRESSURE RESISTANT OUTER CHAMBER; A DEFORMABLE METALLIC CHAMBER WITHIN SAID OUTER CHAMBER FOR CONTAINING FLUID TO BE PUMPED; A PUMP OUTLET CONDUIT COMMUNICATING THROUGH SAID OUTER CHAMBER INTO SAID DEFORMABLE CHAMBER; A HYDRAULIC FLUID INLET CONDUIT COMMUNICATING INTO THE REGION BETWEEN SAID DEFORMABLE CHAMBER AND SAID OUTER CHAMBER; PUMP MEANS FOR INJECTING HYDRAULIC FLUID INTO SAID HYDRAULIC FLUID INLET CONDUIT; A CONDUIT COMMUNICATING WITH SAID DEFORMABLE CHAMBER FOR INJECTING THEREIN FLUID TO BE PUMPED; AN ADDITIONAL CONDUIT COMMUNICATING BETWEEN SAID DEFORMABLE CHAMBER AND THE REGION BETWEEN SAID DEFORMABLE CHAMBER AND SAID OUTER CHAMBER; AND VALVE MEANS IN SAID ADDITIONAL CONDUIT OPERABLE ONLY WHEN SAID FLUID TO BE PUMPED IS BEING INJECTED INTO SAID DEFORMABLE CHAMBER, SAID VALVE MEANS BEING ADAPTED TO PREVENT FLOW OF HYDRAULIC FLUID INTO SAID FLUID TO BE PUMPED BUT TO RELEASE FLUID FROM SAID DEFORMABLE CHAMBER INTO THE REGION BETWEEN SAID DEFORMABLE CHAMBER AND SAID OUTER CHAMBER SHOULD THE PRESSURE OF FLUID TO BE PUMPED EXCEED HYDRAULIC FLUID PRESSURE WHEN THE DEFORMABLE CHAMBER IS BEING FILLED.
