Zusammenfassung:	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.
