ABSTRACT:
A fluidic control device, in particular a vortex amplifier, comprises a casing having fluid inlet, outlet and control ports. A vortex chamber is formed within the casing by a plate which is spaced from a wall of the casing by members which each define a part of the periphery of the vortex chamber. Each member has a channel in communication with a respective control port for introducing control fluid flow into the vortex chamber. An aperture is formed in the plate adjacent each channel to divert a portion of the control flow to the opposite side of the plate and facing the inlet port whereby to reduce instability over the operating range of the amplifier.
