摘要： A hydropneumatic pumping arrangement comprising at least two double-acting hydropneumatic force multipliers, pneumatic chambers of pneumatic cylinders of the multipliers communicating, through two two-position directional valves with an air source, and the chambers communicating through hydraulic non-return valves, with hydraulic pressure and return lines connected to actuating hydraulic cylinders of the associated processing equipment. The valves are cylindrical slide valves, an inlet passage of one slide valve is in communication with an air source and outlet passages are in parallel communication with the pneumatic chambers and with control chambers of another slide valve, outlet passages thereof being in communication with the control chambers of the one slide valve of the other force multiplier for alternate communication of the pneumatic chambers of both multipliers with the air source in the course of travel of the pistons of the pneumatic cylinders thereof. Non-return hydraulic valves are interconnected in two bridge circuits, and there is a system provided for compensating the working fluid flowing out from the chambers of the actuating hydraulic cylinders, which system has its inlets connected with one of the diagonals of each bridge circuit, preferably also communicating them in parallel with the hydraulic chambers of a respective force multiplier, and the other diagonals of each bridge circuit being preferably in communication with the hydraulic pressure and return lines.
