Inventia se refera la un aparat destinat reglajului rapid si precis al debitului de lucru dintr-o instalatie hidraulica. Aceasta se realizeaza prin deplasarea unor supape de pilotare care prin intermediul presiunii de comanda, deplaseaza sertarul principal al unui distribuitor, realizînd un debit proportional cu semnalul transmis.The invention relates to an apparatus for quick and precise flow control of a hydraulic installation. This is accomplished by moving some pilot valves which by means of the control pressure move the main drawer of a distributor, making a flow proportional to the transmitted signal.
