Abstract
A fluidic device which produces fluid pulses having a selected pulse repetition frequency, pulse duration, pulse peak pressure and pulse peak flow rate includes first, second and third fluid flow controlling channels or lumens which converge in a junction, defining a “Y” configuration having a base leg and right and left diverging arms. The first leg portion has a fluid input and terminates downstream at the Y junction of the base and the two diverging arms. The first leg has converging walls which reduce the cross sectional area of the flow to thereby increase the fluid velocity to make a fluid jet. The second or right leg, begins at the Y junction and terminates distally in an enclosed, fluid-tight container having a selected blind volume. The third, or left leg, begins at the Y junction and terminates distally in a fluid outlet passage having a selected cross-sectional area.
