Zusammenfassung:	FLOW CONTROL SYSTEMS AND METHODS FOR USE IN INJECTION WELLS AND IN THE PRODUCTION OF HYDROCARBONS UTILIZE A PARTICULATE MATERIAL DISPOSED IN AN EXTERNAL FLOW AREA (316) OF A FLOW CONTROL CHAMBER HAVING AN INTERNAL FLOW CHANNEL (318) AND AN EXTERNAL FLOW AREA (316) SEPARATED AT LEAST BY A PERMEABLE REGION. THE PARTICULATE MATERIAL TRANSITIONS FROM A FIRST ACCUMULATED CONDITION TO A FREE OR RELEASED CONDITION WHEN A TRIGGERING CONDITION IS SATISFIED WITHOUT REQUIRING USER OR OPERATOR INTERVENTION. THE RELEASED PARTICLES (228) ACCUMULATE WITHOUT USER OR OPERATOR INTERVENTION, TO CONTROL THE FLOW OF PRODUCTION FLUIDS THROUGH A FLOW CONTROL CHAMBER BY AT LEAST SUBSTANTIALLY BLOCKING THE PERMEABLE REGION BETWEEN THE EXTERNAL FLOW AREA (316) AND THE INTERNAL FLOW CHANNEL (318).
