| Abstract | An electrically operated fluid flow valve arrangement (50) includes an electrically powered magnetic field generator (42), a valve body (44) defining a valve chamber (7), an inlet port (5), an outlet port (20)and a valve member (18)located in the chamber (7). The valve member(18) is movable between closed and open conditions relative to one of the ports (5, 20). The valve member (18) includes a permanent magnet (9). The arrangement (50) includes a switchable pole 46 formed of a ferromagnetic material. In use, in a first latched condition, the valve member (18) is retained by the switchable pole (46) in one of the closed or open conditions and,in a second latched condition, in the other of the closed or open conditions, the valve member (18) being moved from one latched condition to the other by operation of the generator (42). |

| Claim | - 58 . (canceled) An electrically operated fluid flow valve arrangement, the arrangement including: an electrically powered magnetic field generator; a valve body defining a valve chamber, an inlet port and an outlet port; a valve member located in the valve chamber and movable between a closed condition in which the valve member locates against one of the ports to substantially prevent fluid flow therethrough and an open condition in which the valve member permits fluid flow therethrough; and a ferromagnetic member having a switchable pole; and the arrangement being such that: the valve member incudes a permanent magnet; the switchable pole is formed of a ferromagnetic material; the ferromagnetic member defines a passage which communicates with the valve chamber via one of the ports; in use, in a first latched condition, the valve member is retained by the switchable pole in one of the closed or open conditions and in a second latched condition, the valve member is in the other of the closed or open conditions; and the valve member is movable from one latched condition to the other by operation of the generator. An arrangement according to claim 59 in which in use in the second latched condition, the valve member is retained by the switchable pole in the other of the closed or open conditions. An arrangement according to claim 59 in which the movement of the valve member between the open and the closed conditions incudes rotational movement. An arrangement according to claim 61 in which the arrangement includes an axis associated with the one port, and in which the rotational movement is around an axis which is not aligned with or parallel to the axis associated with the one port. An arrangement according to claim 59 in which the movement of the valve member between the open and the closed conditions includes substantially linear movement. An arrangement according to claim 59 in which the operation of the generator reverses the polarity of the switchable pole. An arrangement according to claim 59 in which the generator is movable between an unpowered condition wherein no magnetic field is generated, a first operating condition wherein the generator generates a magnetic field in a first direction, and a second operating condition wherein the generator generates a magnetic field in a second and opposite direction, and in which to initiate movement of the valve member between the latched conditions, the generator is moved to either the first operating condition or the second operating condition. An arrangement according to claim 65 in which, in the latched conditions, the generator is in the unpowered condition. An arrangement according to claim 59 in which the ferromagnetic member defines one of the ports. An arrangement according to claim 59 in which the generator comprises a coil which is located around the ferromagnetic member. An arrangement according to claim 59 in which the valve body includes a guide surface for guiding the movement of the valve member between the closed condition and the open condition. An arrangement according to claim 69 in which the guide surface includes a convex part. An arrangement according to claim 59 in which the valve member defines one or more bypass flow channels, which in the open condition permit fluid flow therethrough. An arrangement according to claim 59 in which the arrangement includes a second switchable pole, which assists movement of the valve member between the latched conditions and retention of the valve member in the respective latched condition. An arrangement according to claim 72 in which the second switchable pole is of opposite polarity to the switchable pole. |
