    Abstract: A closure operator to effect remote, failsafe opening and closing of a damper, particularly a multi-fold or interlocking slat curtain damper. A frame or shell envelops a damper curtain which is capable of opening and closing an air passage through the frame or shell. A housing containing an electromechanical curtain operator is optionally positioned within or outside the frame or shell. The curtain is lifted by a tray connected to two wire cables, in response to the winding of the cable upon a takeup drum located within the housing. The principal components of the electromechanical curtain operator are a motor, planetary gear train and its associated latch mechanism which form a clutch, cable drum, speed control brake, and limit switch assembly. All of the foregoing components are protectively contained within an operator housing which is formed with an irregular shaped projecting finger which engages a mating opening formed in a damper supported bracket or in a baffle which isolates the curtain in its open position.

    Abstract translation: 闭合操作器，用于实现阻尼器，特别是多重或互锁的挡板式阻尼器的远程故障安全打开和关闭。 框架或壳体包围一个阻尼器窗帘，其能够打开和关闭通过框架或壳体的空气通道。 包含机电幕帘操作器的壳体可选地定位在框架或壳体内或外部。 响应于将电缆缠绕在位于壳体内的卷绕滚筒上，帘幕被连接到两根电缆的托盘提升。 机电幕帘操作器的主要部件是电动机，行星齿轮系及其相关联的闩锁机构，其形成离合器，电缆卷筒，速度控制制动器和限位开关组件。 所有前述部件被保护地包含在操作器壳体内，该操作器壳体形成有不规则形状的突出的指状物，其接合形成在阻尼器支撑的支架中的配合开口或隔离其打开位置的挡板。
