    • A linear drive power door operator selectively and automatically opens and closes a door swingably mounted on a door jamb. The door operator includes a power screw disposed within a housing and a drive which powers the rotation of the power screw for moving a piston having a threaded bore threadably engaging the power screw linearly upon activation of the drive. A rack having teeth is engaged by the piston for moving the rack linearly from end-to-end. The power door operator further includes a pinion having teeth threadably engaging the teeth of the rack. The pinion is rotatable about a vertical axis upon the side-to-side linear movement of the rack. At least one link arm is pivotally connected at one of its ends to the pinion and pivotally connected at its other end to the door. A control device controls the operation of the drive for moving the door between a closed position and an open position. The control device activates the drive for moving the piston and the rack from a first position in which the door is closed to a second position in which the door is fully open, and any position in between.
    • 线性驱动电源门操作者选择性地并且自动地打开和关闭可摆动地安装在门侧柱上的门。 门操作器包括设置在壳体内的动力螺钉和用于驱动动力螺杆的旋转的驱动器,用于在驱动器的启动时线性移动具有与螺纹孔螺纹接合的螺纹孔的活塞。 具有齿的齿条由活塞接合,以使端子从端到端线性移动。 电动门操作器还包括具有与齿条的齿螺纹接合的齿的小齿轮。 当齿条的侧向线性移动时,小齿轮可绕垂直轴线旋转。 至少一个连杆臂在其一端处枢转地连接到小齿轮,并且在其另一端枢转地连接到门。 控制装置控制用于在关闭位置和打开位置之间移动门的驱动器的操作。 控制装置启动驱动器,用于将活塞和机架从门关闭的第一位置移动到门完全打开的第二位置以及其间的任何位置。
