Abstract

Sistema di regolazione della pressione, comprendente una valvola pilota adatta all'impiego in esso, per fornire una pressione costante da una pompa non-compensata ad una molteplicità di valvole degli ugelli che regolano il flusso da un collettore ad ugelli associati alle valvole, comprendente una valvola regolatrice della pressione interposta tra la pompa ed il collettore, che è sensibile ad una pressione di comando creata da una valvola pilota che riduce la pressione del collettore alla pressione di comando.
