    Abstract: An automatic revolving door drive is described, with a hydraulic piston-cylinder unit with a closing spring and an opener motor, consisting of an electric motor and hydraulic pump. It is a so-called servo closer, with which the door is opened with motor support and automatically closes with hydraulic damping under the influence of the closing spring. In order to be able to use even low-powered opener motors and to produce a relatively compact design, provision is made such that during the motorized opening process the pressure of the hydraulic medium is regulated with adjustment to the prevailing force of the closing spring, in which the closing spring that cooperates with the piston abuts the piston at one end and a hydraulic pressure cushion at the other end, with the same hydraulic pressure being set and regulated by a special pressure-regulating valve in the pressure chamber and in the hydraulic pressure cushion.

    Abstract: A door operating assembly for opening and closing vehicle doors at a constant door edge force includes a frame. A teeter lever assembly is pivotally mounted on the frame and is connected to a connecting rod assembly connecting the teeter lever assembly and the vehicle doors. A cylinder is mounted on the frame and includes a reciprocally mounted rod. The rod is reciprocated by pressurized air introduced into the cylinder. The rod is connected to the teeter lever assembly to rotate the teeter lever assembly. The teeter lever assembly includes a variable diameter cam. A spring for closing the doors is secured at a first end to the frame and at a second end to a flexible connection member. The flexible connection member connects the spring to the cam and wraps around the outer periphery of the cam upon door opening. The energy stored in the spring at full extension is used to close the doors. To maintain the force on the doors constant during opening and closing, the cam provides a larger moment arm in the door closed position than the door open position. To provide closing force for the door an accumulator may be provided. The accumulator includes a container in fluid communication with a vent in the cylinder. As the doors open, air in the cylinder is forced out the vent and into the container. During door closing, air accumulated in the container reenters the cylinder to extend the rod and close the door. An adjustable relief valve may be included with the container to maintain pressure in the container below the source pressure for the cylinder.

    Abstract translation: 用于以恒定的门边缘力打开和关闭车门的门操作组件包括框架。 摇摆杆组件枢转地安装在框架上并且连接到连接摇杆组件和车门的连杆组件。 圆筒安装在框架上，并包括一个往复安装的杆。 杆通过引入气缸的加压空气往复运动。 杆连接到摇杆组件以旋转摇臂组件。 手柄杆组件包括可变直径凸轮。 用于关闭门的弹簧在第一端处固定到框架，并且在第二端处固定到柔性连接构件。 柔性连接构件将弹簧连接到凸轮并且在门打开时围绕凸轮的外周缠绕。 储存在弹簧中完全伸展的能量用于关闭门。 为了在打开和关闭期间保持门上的力恒定，凸轮在门关闭位置提供比门打开位置更大的力矩臂。 为了提供门的关闭力，可以提供蓄能器。 蓄能器包括与气缸中的通风口流体连通的容器。 当门打开时，气缸中的空气被迫排出通风口并进入容器。 在关门期间，积聚在容器中的空气重新进入气缸以延伸杆并关闭门。 可以在容器中包括可调节的安全阀，以将容器中的压力维持在气缸的源压力以下。

    Abstract: A door construction for a vehicle, in particular a railway carriage, comprising a one-leaved or two-leaved door which through the intermediary of one or more brackets, secured to a rotatable, vertical shaft, can be opened or closed by rotating said shaft, and a drive means for rotating said rotatable shaft, which drive means acts through the intermediary of a linkage on a first arm secured to said rotatable shaft, and by means of which the door can be locked in the closed position. In the closed position of the door, the linkage can be locked in a single point according to the overcenter closing principle.

    Abstract: A safety apparatus is associated with otherwise conventional revolving doors which are rotatable about a vertical axis. A pair of closure components are positioned adjacent to the respective sides of a revolving door and are displaceable in the horizontal direction. The closure components include profiled surfaces which delimit access space of the revolving door. In case of emergency situations, e.g. caused by a fire, the closure components are moved away from one another under the power of two respective jacks, leaving access space around the sides of the door wide enough for the passage of persons.
