20130008513 | FLOW CONTROL DEVICE AND FLOW CONTROL METHOD - Disclosed herein is an improved method for reversed flow through a self-adjustable (autonomous) valve or flow control device ( | 01-10-2013 |
20140027126 | AUTONOMOUS VALVE - The invention relates to a method and apparatus for of controlling the flow of a fluid. The fluid comprises a liquid phase and a dissolved gas phase. The fluid passes through a valve, the valve comprising a fluid inlet and a movable body located in a flow path through the valve, the movable body being arranged to move freely relative to the opening of the inlet to vary the flow-through area through which the fluid flows by means of the Bernoulli effect. The dimensions of the valve are such that flow of the fluid past the movable body causes a drop in pressure to below the bubble point of the gas phase in the liquid phase, thereby increasing flow of the fluid through the valve. | 01-30-2014 |
20140209822 | AUTONOMOUS VALVE WITH TEMPERATURE RESPONSIVE DEVICE - A self-adjustable valve or flow control device for controlling the flow of a fluid from one space or area to another by exploiting the Bernoulli principle, to control the flow of fluid, such as oil and/or gas including any water, from an oil or gas reservoir and into a production pipe of a well in the oil and/or gas reservoir, from an inlet port on an inlet side to an outlet port on an outlet side of the device. The valve includes a movable valve body arranged to be acted on by a temperature responsive device. The valve body is arranged to be actuated towards its closed position by the temperature responsive device in response to a predetermined increase in temperature in the fluid surrounding and/or entering the valve. The temperature responsive device includes an expandable device including a sealed structure at least partially filled with an expandable material | 07-31-2014 |
