Abstract
Pulsations are created in a fluid flow stream by a pulsatile device. The device includes a flexible, resilient element which oscillates under the influence of a pressure differential to interrupt the fluid flow at regular intervals, thereby causing the outlet flow to pulsate. The device may be connected directly to a supply of fluid under pressure.
