A switch valve contacts flexible tubes that connect caps for printheads to a pump. The switch valve includes a tube support. The support is formed with grooves receiving intermediate portions of the flexible tubes, which tubes are curved along rounded corner sidewalls that project toward an entrance of the support. A rotary member controls pivotal motion of a lever. The lever pivots in one direction to squeeze one of the tubes against the associated one of the corner sidewalls, and it pivots in the opposite direction to squeeze the other one of the tubes.
L'invention concerne une vanne de commutation en contact avec des tubes souples qui raccordent des capuchons de tête d'impression à une pompe. La vanne de commutation comporte un support de tubes. Le support est doté de rainures recevant des portions intermédiaires des tubes souples. Ces tubes sont incurvés le long de parois latérales d'angle arrondies qui font saillie vers une entrée du support. Un élément tournant commande le pivotement d'un levier. Le levier pivote dans un sens de manière à coincer l'un des tubes contre l'une des parois latérales d'angle, et il pivote dans le sens opposé de manière à coincer l'autre tube.
