    • A linear actuator comprising of two elongate resilient elements (10, 12) joined together at their opposite ends (13, 14), a first one of the elements is fixed at a point intermediate its ends (16) and the two elements (10, 12) are arranged to carry an electric current which causes the two elements (10, 12) to move apart when they are placed in a transverse magnetic field. The linear actuator may be used to control the opening and closing of a valve in a fluid dispensing device, where a needle (20) is attached to the second element (12), which needle co-operates with a valve orifice.

    • An electromagnetic linear drive including at least two stators divided into motor elements which constitute two paths of movement for movable vehicles in opposite directions is disclosed. An energy supply unit, including a power control unit, is associated with each of two opposed motor elements belonging to one or the other path of movement. The energy supply unit is selectively connectable to the motor element of one path of movement or to the motor element of the other path of movement, as required. When a vehicle is located above both motor elements associated with a single energy supply unit, the common energy supply unit is connected, according to a predetermined selection, to one of the two motor elements or alternated between both motor elements.
    • 公开了一种电磁线性驱动器,其包括分成电动元件的至少两个定子,所述电动机元件构成相反方向上的可移动车辆的两个运动路径。 包括功率控制单元的能量供应单元与属于一个或另一个运动路径的两个相对的电动机元件中的每一个相关联。 根据需要,能量供应单元可选择性地连接到一个运动路径的电机元件或另一个运动路径的电机元件。 当车辆位于与单个能量供应单元相关联的两个电动机元件上方时,共同能量供应单元根据预定选择被连接到两个电动机元件中的一个或两个电动元件之间交替。
