Beschreibung
Zusammenfassung:	A flow control assembly includes a housing defining flow port that place an interior of the housing in fluid communication with an exterior of the housing, and a sliding sleeve defining sleeve ports and movably positioned within the interior between a first position, where fluid communication between the interior and the exterior via the flow ports is prevented, and a second positon, where fluid communication between the interior and the exterior is facilitated through the sleeve ports and the flow ports. A piston and a slip device are movably arranged within a piston chamber defined between the housing and the sliding sleeve. The piston has a first end exposed to an interior pressure and a second end exposed to an exterior pressure via chamber ports defined in the housing. A biasing device is also positioned within the piston chamber.
