  • Passive device for balancing the pressure of first and second fluids and the use thereof
    Patent number: 7377288
    Abstract: The device comprises a first valve (35a) and a second valve (35b) each comprising a chamber (13a, 13b) communicating via an admission orifice (19a, 19b) with a circuit or a receptacle containing a first or a second fluid, and via an exhaust orifice (18a, 18b) with exhaust means for the first or the second fluid, at least one valve member (20a, 20b) mounted to move within the valve chamber (13a, 13b) between a position for closing and a position for opening the exhaust orifice (18a, 18b), a piston (22a, 24a, 22b, 24b) connected to the valve member (20a, 20b) and resilient return means (32a, 32b) for returning the valve member (20a, 20b) to a closed position. Each of the first and second pistons (22a, 24a, 22b, 24b) has a first face exposed to one of the first and second fluids, and an opposite second face subjected to a force exerted respectively by the second fluid or by the first fluid.
