Abstract

Viene descritto un sistema di valvola limitatrice di pressione con una struttura la quale permette di mettere a disposizione una molteplicità di diverse funzioni limitatrici di pressione con un minimo in variazioni strutturali. A questo scopo un corpo standard di valvola a vie è equipaggiato di un inserto valvolare, il quale permette di strutturare una valvola limitatrice doppia di pressione con un sistema di pressione regolabile individualmente su ogni lato della valvola, dall'altro lato però essendo data anche la possibilità di eliminare completamente il sistema di pressione su un lato. L'inserto valvolare e/o i corpi valvolari sono preferibilmente intercambiabili, e i corpi valvolari sono separatamente comandabili da un dispositivo di regolazione per esempio nella forma di un magnete proporzionale per produrre un segnale di uscita della pressione, corrispondente ad un segnale di entrata, in ciascuno dei sistemi di pressione fra loro indipendenti.
