Abstract

Una macchina per stampaggio ad iniezione con uno stampo (20), un dispositivo di iniezione per materia sintetica plastificata e con un accumulatore di pressione (6) per un gas. Il gas è alimentato all'accumulatore (6) attraverso un dispositivo per aumentare la pressione del gas da un serbatoio (8) e proveniente attraverso una tubazione di alimentazione dall'accumulatore (6) allo stampo (20). Alla tubazione di alimentazione è collegato un compressore (3) a stantuffo, il cui stantuffo (11) durante l'insufflamento di gas nello stampo (20) è mobile di ritorno, e così il compressore (3) a stantuffo forma un riduttore di pressione.
