    • A valve actuator assembly that is implemented in a fully-electric configuration includes two rails and an armature that is moveably disposed between, and electrically coupled to, each of the rails. The armature is configured to couple to a valve element and is moveable between at least a first position and a second position, to thereby move the valve element to at least the open and closed positions, respectively. Upon application of an electrical potential of a first or second polarity across the rails, a current flows through the armature in a first or a second direction, respectively, to thereby generate a Lorentz force. The Lorentz force acts on the armature to move it to the first or second position, and thus move the valve element to the open or closed position, respectively.
    • 以全电气构造实现的阀致动器组件包括两个轨道和可移动地设置在每个轨道之间并且电耦合到每个轨道的电枢。 电枢被配置为耦合到阀元件并且可以在至少第一位置和第二位置之间移动,从而分别将阀元件移动到至少打开和关闭位置。 当跨越轨道施加第一或第二极性的电势时,电流分别沿第一或第二方向流过电枢,从而产生洛伦兹力。 洛伦兹力作用在电枢上以将其移动到第一或第二位置,从而分别将阀元件移动到打开或关闭位置。
