摘要： An improved pinch valve includes a camshaft and associated cam(s) controlling the position of a pivotally-mounted first pinch arm and an opposed, pivotally-mounted second pinch arm. The respective pinch arms are provided symmetrically about a central plane which contains an axis of the camshaft. A spring extends across the central plane and interconnects the respective pinch arms so as to urge both pinch arms towards the central plane. A mechanical advantage lever is provided such that the pinching force is greater than the spring force.

摘要： An inkjet printer includes: an inkjet printhead; an ink delivery system configured for supplying ink to the printhead at a negative hydrostatic pressure; and an air chamber in fluid communication with the ink delivery system. The air chamber has an air-permeable wall which is impervious to the ink. The air chamber provides dampening of pressure fluctuations in the ink delivery system and, further, is self-recovering from ingress of ink into the air chamber.
