Patent

CA 2541204

The invention relates to a flow control device which is insertable into a fluid pipeline (K) and comprising a valve (1), an obturator with membrane (2), and anchoring flaps (3) that can deploy like umbrella spokes under the action of an elastic stress until it presses against the wall (P) of the pipeline (K). According to the invention, the membrane (2) and the flaps (3) are mutually attached to and disposed on a same side of the valve body (10) , so that as the flaps (3) deploy the membrane (2) deploys at the same time until the membrane presses against the internal wall of the pipeline (K) and the fluid exerts on the deployed membrane a pressure which increases the pressure of the flaps (3) against this wall (P).
