Abstract: A gas flow control device for injecting gas into a production string for recovering pressure and reducing frictional losses, so that critical flow can be reached at lower pressure drops and higher production pressure, includes a nozzle having first and second ends, and a flow path therebetween, and a Venturi having first and second ends, and a flow path therebetween. The first end of the Venturi is disposed adjacent to the second end of the nozzle. The Venturi flow path is aligned with the nozzle flow path to provide a continuous flow path through the valve.
