Abstract
An apparatus and method are for printing a fluid material by a continuous jet printing technique. The apparatus includes a flow restricting structure arranged near an outflow opening for restricting a flow of the material between a reservoir and the outflow opening by a restricted passage through the flow restricting structure. Furthermore, the flow restricting structure, an actuating surface, and a nozzle are arranged to bind a micro volume directly adjacent an inside of the outflow opening for the purpose of guiding or reflecting pressure variations generated by the pressure regulating mechanism towards the outflow opening.
