U.S. Patent 4,097,872 describes an axial drop aspirator for a continuous ink jet. Within the settling chamber of the aspirator are a pair of flow smoothing screens which serve to distribute the pressure evenly downstream of the air entrance side and to make more uniform the air flow therethrough. Described below, and shown in the figure, is an air-flow smoothing device or screen to help produce homogeneous laminar air flow.
