The invention relates to a door actuator with a motor-gear unit and a spr ing (7) acting as an energy storage device. To produce a door actuator, wher ein two variants are formed for sliding or shear rails by substituting an in dividual component, the pretensioning of the spring (7) can be actively vari ed by the motor-gear unit, thus producing the desired closure torque profile . |
