<p>of the disclosure An electrically actuated valve for control of a pressurized fluid, particularly a sanitary valve, comprises a rotor (15) arranged in a housing (1) between an inlet passageway (6) and an outlet passageway (7). The rotor (15) is rotatable under the action of the pressurized fluid and transports portions of the fluid from the inlet passageway (6) to the outlet passageway (7). There is an operational connection between the rotor (15) and an element (19) rotatably arranged in a chamber (21) filled with an electro-viscous liquid (22). The electro-viscous liquid (22) is arranged between two electrodes (23, 24) to which as high voltage (25) can be applied. In one embodiment of the invention the rotor (15) also forms the closure element of the valve, which is braked to a various extent by the rotatable element (19) arranged in the electro-viscous liquid. In a further embodiment rotation of the rotor will supplied to a closure member via the rotatable element, which will then be an element of a clutch, and gear means. (figure 2)</p> |
