摘要： Disclosed herein is an improved method for reversed flow through a self-adjustable (autonomous) valve or flow control device (2), comprising the step of providing an overpressure on the side of the valve (2) opposite of the side of the inlet (10) exceeding a predetermined biasing force of the resilient member (24) causing lifting of the inner body part (4a) within the outer body part (4b) against said biasing force from a first position of fluid flow between an inner and an outer side of the valve (2) via the flow path (11) and to a second position of reversed fluid flow between said inner and outer side through the second flow path (25). An improved self-adjustable (autonomous) valve or flow control device (2) and use of said improved valve or flow control device are also disclosed.

摘要： 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.
