摘要： High pressure hydraulic pump system without external energy requirements and procedure for putting said system into practice.
The system is designed as a hydraulic pump, for water or another incompressible fluid at a high pressure and without any external energy requirements, based on a positive displacement hydraulic machine and formed by, at least, two parallel columns of vertical load fed from an upper tank (6) of fluid, so that said parallel columns end in respective sets of two actuator cylinders with pistons, with two actuator cylinders (1) and (2) being connected at the base thereof by means of a transversal pipe (5) and comprising discharge pipes at the heads thereof with charge and discharge valves (10-10') and (11-11'), together with two suction-impulsion work cylinders (3) and (4) for bringing the fluid to be pumped from a lower tank (7), through pipes (12) and (13) with non-return valves (15-16-17-18), with the actuator cylinders (1) and (2) and the work cylinders (3) and (4) being connected together by means of a rod shared by the corresponding pistons (1'-2') and (3'-4') respectively.
