Abstract

Il presente trovato concerne una valvola automatica di by-pass. Un corpo valvola (1) a tre vie ingresso (2), uscita (3) e riflesso (4), dotato di un otturatore (5) della via di riflusso (4) e di un otturatore (10) della via d'uscita (3), é collegato, tramite uno stelo (6), a uno stantuffo (7), alloggiato in un cilindro (31), il quale comunica con la via d'uscita (3) attraverso un condotto (9). Un condotto di ricircolo (12) mette in comunicazione la detto via d'uscita (3) con una camera di ricircolo (13) comunicante con la detta via di riflusso (4) attraverso una luce di ricircolo (14) chiusa da un otturatore (15), la cui apertura è determinata dall'azione su di esso di un'asta (18), che interviene solidalmente con l'otturatore (5).
