Abstract

Testina di stampa a getto d'inchiostro in cui l'inchiostro contenuto in una camera è espulso attraverso un ugello sotto forma di gocce in seguito all'istantaneo riscaldamento di un elemento riscaldatore interno alla camera. La camera di forma poligonale comunica con uno o più canali di alimentazione dell'inchiostro disposto in corrispondenza di uno spigolo della camera allo scopo di aumentare la frequenza di espulsione delle gocce, senza alterare le condizioni di smorzamento delle vibrazioni del menisco nell'ugello.
