ABSTRACT:
A valve array for supporting objects such as paper with controlled fluid flow is disclosed. Optional valve arrays can be used to controllably eject marking agents for marking or coating a paper or other suitable substrate. Each valve in the valve array has one or more flap elements positioned in a valve chamber. These flap elements are movable to alternatively block the fluid flow through valve chamber outlets with the aid of various catch mechanisms for controllably latching the flap elements. The catch mechanisms have a disabled state and an activated state for holding and allowing release of the flap elements. Once the catch mechanism are disabled, the flap elements are free to move to another position, provided they can overcome the mechanical fluid flow forces that tend to hold it in position. To counter and utilize such forces for moving the flap elements, an impulse mechanism kicks the flap element into the valve chamber, away from the catch mechanisms. Since the position of the flap elements is unstable, oscillations of the flap elements in the fluid flow will eventually bring the flap element into catchment range of another catch mechanism in an activated state.
