ABSTRACT:
A flow control device which consists of a tubular body having radial sets of orifices therein covered by a resilient member which defines an annular space to which the orifices are connected. The resilient member permits positive pressure to drive fluid through the orifices but prevents negative pressure from sucking air through the orifices. A spring urges the resilient member against one of the sets of orifices.
