<p>An apparatus for forming a thin stream of fluid which intermittently strikes a target in accordance with externally supplied command data. Pressurized fluid from a manifold is passed through a relatively stiff section of tubing which is directed at the desired target. The tubing is cantilevered from the manifold, and has associated therewith a plunger which, when extended, contacts the cantilevered tube and deflects the free end of the tube. In one embodiment, the tube in its deflected position is directed at the desired target, and in its unreflected position is directed at a barrier.</p> |
