  • Bidirectional thermal syphon valve, installation for the production and storage of heat or cold comprising such a thermal syphon valve, and various uses
    Patent number: 4531510
    Abstract: The invention relates to a bidirectional thermal siphon-valve operating by natural convection. It further relates to an installation for the production and storage of heat or cold comprising such a thermal siphon-valve, preferably with a continuously operating pump.The thermal siphon-valve functions to direct a heat-transfer fluid toward one of two hydraulic circuits, or to divide it between the two circuits, on the basis of its temperature. It is distinguished by the fact that it comprises an entirely internally open tubular body (14) with a vertical axis which is provided with at least one inlet orifice (10a) for the heat-transfer fluid, located substantially in its middle portion, and two outlet orifices (10b, 10c) for the heat-transfer fluid, located in its lower and upper portions, respectively.
