A suction apparatus includes a volume-variable chamber having an inlet and an outlet which is formed by a plurality of enclosing parts including an elastic part. A slider applies a force to the volume-variable chamber to decrease the volume thereof and a valve applies a force to increase the volume thereof. When the slider decreases the volume, the valve opens the outlet to drain ink and air from the volume-variable chamber. When the valve increases the volume, the valve closes the outlet to produce a suction force.

Dispositif d'aspiration pourvu d'une chambre à volume variable qui possède une entrée et une sortie, et qui est constituée de nombreux éléments d'enveloppe y compris une partie élastique. Une coulisse applique une force sur la chambre pour en diminuer le volume, et une soupape applique une force sur celle-ci afin d'en augmenter le volume. Lorsque la coulisse diminue le volume de la chambre, la soupape ouvre la sortie pour drainer l'encre et l'air de cette chambre. Lorsque la soupape augmente le volume de la chambre, elle ferme la sortie afin de produire une force d'aspiration.
