    摘要: A fluidic ventilation control system comprises a pair of vortex valves (3, 4) connected axial port to axial port in a passageway (7, 8) which can connect a main tunnel (1) with a service tunnel (2). The tangential ports of the vortex valves communicate with pressure gas supply (13), with valves (11, 12) to control the supply of pressure gas to the vortex valves. The valves (11, 12) are responsive to signals generated by sensors, such as pressure and heat detectors, in the tunnels to control the supply of pressure gas to thereby regulate the flow in the passageway in response to changes in conditions in the tunnels.
