The invention relates to a door actuator with a motor-gear unit and a spring (7) acting as an energy storage device. To produce a door actuator, wherein two variants are formed for sliding or shear rails by substituting an individual component, the pretensioning of the spring (7) can be actively varied by the motor-gear unit, thus producing the desired closure torque profile.
L'invention concerne un entraînement de porte, comprenant une unité moteur-engrenage et un ressort (7) agissant comme un accumulateur d'énergie. L'objectif de l'invention consiste à créer un entraînement de porte, dans lequel l'échange d'un composant unique permet de former deux variantes pour bras articulé et/ou bras à glissière. À cet effet, la précontrainte du ressort (7) de l'unité moteur-engrenage peut être modifiée activement, produisant ainsi l'allure souhaitée du moment de fermeture.
