Force transmitting system

Claim 1

IN A SEALED FORCE TRANSMITTING HYDROSTATIC SYTEM FOR ASSOCIATION WITH AN ACTUATING DEVICE AND A RESPONDING DEVICE, AND INCLUDING AN ACTUATING TRANSDUCER FOR CONVERTING FORCE APPLIED THERETO BY THE ACTUATING DEVICE INTO LIQUID PRESSURE AND A RESPONDING TRANSDUCER FOR CONVERTING LIQUID PRESSURE APPLIED THERETO INTO FORCE APPLIABLE TO THE RESPONDING DEVICE, THE IMPROVEMENT IN WHICH EACH OF SAID TRANSDUCERS COMPRISES A HOLLOW CYLINDER ASSEMBLY HAVING AN INTERIOR WALL SURFACE AND A CAVITY THEREWITHIN, A ROLLLING LOBE DIAPHRAGM HAVING A PERIPHERAL LIP FIXED WITH RESPECT TO SAID CYLINDDER ASSEMBL SECURED TO SAID DIAPHRAGM AND MOVABLE LONGITUDINALLY OF SAID CYLINDER ASEMBLY AND SUBSTANTIALLY COAXIALLY THEREWITH AND CONNECTABLE TO ONE OF THE ACTUATING AND RESPONDING DEVICES; SAID DIAPHRAGM HAVING A SURFACE ENGAGEABLE WITH THE INTERIOR WALL SURFACE OF SAID CYLINDER ASSEMBLY AND WITH SAID PISTONN AND TRANSFERRING FROM ONE TO THE OTHER DURING MOVEMENT OF SAID PISTON LONGITUDINALLY OF SAID CYLINDER ASSEMBLY AND HAVING A ROLLING LOBE BETWEEN SAID INTERIOR WALL SURFACE OF SAID CYLINDER ASSEMBLY AND SAID PISTON; A SEALED LIQUID CONDUIT SEALED TO AND INTERJOINING SAID CAVITIES OF SAID TRANSDUCERS, A LIQUID HAVING A TEMPERATURE COEFFICIENT OF EXPANSION FILLING SAID CAVITIES AND SAID CONDUIT, THE EFFECTIVE VOLUMES OF SAID CAVITES VARYING INVERSELY WITH ONE ANOTHER AS SAIDD PISTON MOVE DURING OPERATION OFF THE SYSTEM, EACH OF SAID PISTONS BEING MOVABLE TO A POSITION WITHIN ITS ASSOCIATED CYLINDER ASSEMBLY TO CAUSE THE CAVITY TO BE GENERALLY TUBULAR IN FORM OVER A PORTION OF ITS LENGTH, AT LEAST ONE OF SAID TUBULAR FORMED CAVITIES EXISTING AT ALL CONDITIONS OF OPERATION OF THE SYSTEM, SAID CYLINDER ASSEMBLY OF AT LEAST ONE OF SAID TRANSDUCERS HAVING A HIGHER TEMPERATURE COEFFICIENT OF EXPANSION THAN TTHE PISTON THEREOFF FOR INCREASISNG THE PERCENTAGE DIFFERENTIAL RATE OF VOLUME CHANGE OF THE CAVITY WITH A CHANGE IN TEMPERATURE.
