Self-adjusting hydropneumatic kinetic energy absorption arrangement

Claim 1

A SELF-ADJUSTING HUDROPENUMATIC KINETIC ENERGY ABSORPTION ARRANGEMENT, COMPRISING A FIRST HYDRAULIC CYLINDER INCLUDING A FIRST HYDRAULIC CHAMBER WITH A RESTRICTED OUTLET ORIFICE AND A RELATIVELY UNRESTRICTED OUTLET PORT, AND A FIRST PISTON THEREIN HAVING A DRIVING PORTION EXTENDING EXTERIORLY THEREOFF A HIGH-PRESSURE LOW-VOLUME HYDROPENUMATIC ENERGY ACCUMULATOR INCLUDING A SECOND HYDRULIC CYLINDER AND A SECOND PISTON THEREIN DIVIDING SAID SECOND CYLINDER INTO A SECOND HYDRAULIC CHAMBER HYDRAULICALLY CONNECTED TO SAID ORIFICE AND A FIRST PNEUMATIC CHAMBER CONTAINING A RELATIVELY HIGH PRESSURE GAS; A LOW-PRESSUR HIGH-VOLUME HYDROPENUMATIC ENERGY STORAGE ACCUMULATOR HAVING A THIRD HYDRAULIC CYLINDER AND A THIRD PISTON THEREIN DIVIDING SAID THIRD CYLINDER INTO A THIRD HYDRAULIC CHAMBER AND A SECOND PNEUMATIC CHAMBER CONTAINING A GAS AT A RELATIVELY LOW PRESSURE, AND AUTOMATIC CONTROL VALVE MEANS SELECTIVELY INTERCONNECTING SAID SECOND AND THIRD HYDRAULIC CHAMBERS AND INCLUDING A HYDRAULIC VALVE-OPERATING DEVICE HYDRAULICALLY CONNECTED TO SAID OUTLET PORT, SAID CONTROL VALVE MEANS BEING TEMPORARILY RESPONSIVE TO BACK PRESSURE THROUGH SAID OUTLET PORT RESULTING FROM RETARDATION OF HYDRAULIC FLUID FLOW OUT OF SAID ORIFICE UPON IMPRESSION OF KINETIC ENERGY ON SAID DRIVING PORTION TO NORMALLY CLOSE COMMUNICATION BETWEEN SAID SECOND AND THIRD HYDRAULIC CHAMBERS BUT SUBSEQUENTLY RESPONSIVE TO RISE OF PRESSURE BEYOND SAID ORIFICE TO OPEN COMMUNICATION THEREBETWEEN AND DISCHARGE HYDRAULIC FLUID FROM SAID SECOND HYDRAULIC CHAMBER INTO SAID THIRD HYDRAULIC CHAMBER.
