Abstract
A vortex amplifier functions as a choke valve to control flow in a flow line from, for example, a gas or oil well. The vortex amplifier is arranged in the flow line 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 by a pump. The pump is regulated by a transducer responsive to signals generated by the flow in the flow line.
