Abstract
A droplet jetting device comprising a membrane layer defining a pressure chamber that is in fluid communication with a nozzle, the membrane layer carrying, on a membrane that covers the pressure chamber, an actuator for generating pressure waves in a liquid in the pressure chamber, the device further comprising a distribution layer bonded to the membrane layer on the side of the membrane and defining a supply line for supplying the liquid to the pressure chamber, the supply line being connected to the pressure chamber via a restrictor passage extending through the distribution layer in the thickness direction of that layer, and via a window formed in the membrane, characterized in that the restrictor passage has a uniform cross-section, and the membrane window is delimited by a contour that is inwardly offset from the contour of the restrictor passage on the entire periphery of the restrictor passage.
