Abstract

L'invenzione riguarda un dispositivo per lo smorzamento delle vibrazioni, particolarmente nei condotti dei gas di scarico di autoveicoli, che richiede un minor dispendio di materiale rispetto ai dispositivi finora noti, è di fabbricazione più semplice, e in particolare consente una maggior automatizzazione e razionalizzazione. Un dispositivo secondo l'invenzione presenta cuscini ammortizzatori di filo metallico pressato disposti in un contenitore ed è eseguito disponendo mobilmente l'uno rispetto all'altro tratti di parete frontali esterni del contenitore disposti l'uno accanto all'altro, come elementi di reazione dei cuscini ammortizzatori.
