Autonomous valve

The invention relates to a self-adjustable, or autonomous, valve or flow control device for controlling the flow of a fluid from one space or area to another. The valve is particularly useful for controlling the flow of fluid from a reservoir and into a production pipe of a well in the oil and/or gas reservoir, between an inlet port on an inlet side to at least one outlet port on an outlet side of the flow control device. A freely movable valve body is located in a recess in the flow control device, wherein the fluid is arranged to flow out of the recess radially across a first surface of the valve body, said first surface facing the central aperture, and past the outer peripheral surface of said valve body towards at least one outlet port. Such a production pipe can include a drainage pipe comprising at least two sections each including one or more inflow control devices.
