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.

摘要： A vortex amplifier (1) functions as a choke valve to control flow in a flow line from, for example, a gas or oil well. The vortex amplifier (1) is arranged in the flow line (2, 3) such that flow passes radially through the vortex amplifier to emerge at an axial port. A control flow is introduced tangentially into the vortex amplifier along a line (4) by a pump (5). The pump (5) is regulated by a transducer (7) responsive to signals generated by the flow in the flow line (3).
