Abstract:
A flow control valve for use inside a wellbore. In one implementation, the flow control valve may include a housing, a chamber disposed inside the housing and an entry port disposed at a first end of the chamber. The entry port may be configured to allow fluid to enter into the chamber. The flow control valve may further include an exit port disposed at a second end of the chamber. The second end may be opposite of the first end and the exit port is configured to allow fluid to flow out of the chamber. The flow control valve may further include a check valve assembly disposed between the entry port and the exit port. The check valve may be configured to allow fluid to flow from the entry port to the exit port and to prevent fluid to flow from the exit port to the entry port.
