<p>The present invention relates to a system that automatically increases or decreases flow in tubes when exposed to temperature variations and to a tube that automatically stops fluid from flowing when exposed to heat. The system comprises a plurality of members at least one of the members being an element arranged inside a tube, thus definig a longitudinally extending flow channel between the element and the tube. The element and the tube have different thermomechanical properties, so that the cross-sectional-area of the flow channel varies when the system is exposed to temperature variations.</p> |
