A fluidic device, in particular a vortex diode, has a vortex chamber formed by spaced apart end walls and a peripheral side wall. An axial port is provided in one end wall and a further port permitting tangential flow into or out of the chamber is provided in the other end wall.

A method of forming a fluidic device comprising providing a fluid flow conduit having a conduit wall, connecting axially spaced end walls across the conduit to define a vortex chamber having an imperforate peripheral wall defined by said conduit wall, providing an axial port in only one of the end walls and providing a tangentially directed port in the other of the end walls opening into said fluid flow conduit such that fluid flowing in the conduit in a first direction flows through the tangentially directed port tangentially into the vortex chamber creating a vortex within said chamber so as to provide relatively high resistance to flow whereas fluid flowing in said conduit in a second direction flows through said axial port axially into said vortex chamber without forming a vortex within said chamber so as to provide a relatively low resistance to flow.
