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.
