Abstract

Tête de machine à mouler au sable. Quand on envoie de l'air comprimé par 7, la membrane 11 étant soulevée et la membrane 12 appliquée contre son siège, en même temps que par 21 l'on provoque l'abaissement du piston 18 et du clapet creux 3, le sable contenu dans 2 s'écoule dans le cylindre 1 de la machine à mouler tandis que de l'air sort par 13 et 14 en traversant la couche filtrante 15 faite de petits cylindres perforés et en répartissant le sable dans 1. Quand on inverse l'actionnement des membranes et du piston, 3 remonte et l'air résiduel peut s'échapper par 10 sans entraîner du sable. Industrie de la fonderie au sable.
