Abstract
Improvements in the devices to automatically regulate the flow in a hydraulic circuit that feeds at least one operating device the circulation of a fluid to such device at a pre-established value, said circuit comprising at least one pressurized fluid fluid supply source of a constant output flow, characterized in that it comprises a flow transducer that emits an electrical output signal depending on the value of the flow supplied to said operating device, at least one valve arranged to discharge a variable amount of fluid at the outlet of said power supply and a first programmer and controller means that receives said output signal from said transducer, adjusting the aforementioned flow value preset in the first mentioned means, which is suitable for controlling, through a second means, the mentioned quantity of fluid discharged by said valve, in order to maintain and The value of the flow fed to the operating device at a level equal to that of said preset value in case of variation of the flow pressure in said device, the flow being discharged by said valve at substantially the same pressure as the fluid supplied to the operating device. .
