Abstract

Open oleo dynamic circuit with automatic sequence for controlling piston-operated pumps, in particular for pumps for concrete, in which the stability of the hydraulic system is obtained in all operating conditions and cylinder positions, of the type comprising two pumping cylinders, two operating cylinders for a shunt valve via which the pumping cylinders are put into communication alternately with a delivery tube and with a loading hopper and hydro-valves for controlling the said cylinders. In this circuit the control of the said hydro-valves is obtained by means of secondary hydro-valves with the functions of relays, operated directly by the supply flow of the oleo dynamic cylinders operating the pump, the intervention of which is foreseen only on reaching the end stop position.
