Abstract
Cet appareil comprend une unité d'éjection A ayant une chambre de liquide 3, 5 reliée à un réservoir 22 et une chambre à air 7 reliée à une source 14 d'air sous pression à travers une conduite 10. Des canaux d'évacuation alignés axialement 6, 8 permettent le débit de l'encre contenu dans la chambre de liquide. Un traducteur piézoélectrique 1 est monté à côté de la chambre de liquide 3 pour engendrer des augmentations rapides de pression. Le réservoir d'encre 22 est également alimenté avec de l'air sous pression 21, de façon qu'il existe un courant d'air constant à travers le canal d'évacuation 8 et un équilibre de pression statique entre les chambres d'air et de liquide 7, 5 lorsque la source d'air est en service. Un dispositif 29, 30, 31 sert à communiquer une action de retardement à la variation transitoire de la pression dans la conduite 10 lors de la mise en service de la source 14.
