Abstract

PURPOSE:To increase pressure feeding efficiency by driving a piston rod by means of a valve driving cylinder, alternately opening and closing a suction port and a discharge port, and reciprocating a piston in a pressure feeding cylinder by means of a hydraulic cylinder. CONSTITUTION:A hydraulic pump 8, a cylinder 3, and valves 9, 11, 15, 16 are provided in the hydraulic system of the valve driving cylinder 7 of a pump. Oil is fed under pressure into the pressure feeding cylinder 3 while concrete is discharged by the operation of a valve, and a rotary valve on a discharge side is controlled in its opening/closing by the valve driving cylinder 7. Thereby, a fluid can be continuously fed under pressure by means of a hydraulically driven single barrel type pump.
