Abstract

Grâce à l'orifice d'aspiration d'un dispositif d'aspiration appliqué sur une machine, on peut choisir automatiquement de procéder ou non à l'établissement d'un vide. Un orifice de succion (2) est placé au bas d'un corps principal (1), donnant accès à un corps de soupape (3) prenant en permanence appui sur des montants latéraux (4). Une autre soupape (5) est aussi montée sur les supports (4) et munie de plusieurs lumières d'aspiration circulaires (6) vers l'intérieur de la périphérie externe de la soupape et vers l'extérieur de la périphérie externe d'une ouverture de succion (9). Le corps de soupape (3) présente à sa surface supérieure un siège de soupape (7) et on trouve un conduit d'air (8) menant vers le haut, au centre de la surface supérieure du corps de soupape (3). L'ouverture de succion (9) se trouve à l'extrémité supérieure de ce conduit d'air (8) et communique avec une chambre d'aspiration (10). Une lumière de succion (11) est placée sur la surface supérieure de cette chambre d'aspiration (10).
