Abstract

Il compressore comprende una valvola supplementare (30, 18; 40a) atta a porre in comunicazione permanente la camera di lavoro (5) dello stantuffo con l'apertura di aspirazione (13a) attraverso un condotto (18) quando ad un ingresso di comando (2c) del compressore (2) viene alimentata aria in pressione. Tale valvola supplementare comprende un passaggio (30) che interseca detto condotto (18) e che comunica con il suddetto Ingresso di comando (2c) e un organo valvolare a stantuffo (40) spostabile in modo scorrevole in tale passaggio (30) per effetto di una pressione alimentata a detto ingresso di comando (2c), contro l'azione di una molla di contrasto (41), da una posizione di riposo in cui intercetta il condotto (18) ad una posizione di lavoro in cui, attraverso detto condotto (18), consente la comunicazione permanente fra l'apertura di aspirazione (13a) e la camera di lavoro (5).Fig. 2
