  • the drive according to the invention for a wing of a door or a window has a designed as a compression spring energy storage, which is charged by manual opening and causes the wing is guided after opening again in its closed position.
  • door drives are used for this purpose, which effect the introduction of force onto the door via a linkage connected in a hinged manner or via a lever guided in a slide rail by a sliding block.
  • the door drive can be fixed to the frame or on the door leaf.

  • the spring piston is assigned no valve function, whereby a simple construction is possible.
  • the various areas in the receiving space are interconnected by overflow, wherein the overflow can be formed in the housing, for example, during the manufacture of the housing through Extrusion, or they are subsequently produced by machining by drilling or by spark erosion.
  • valves can be arranged, which serve to influence the behavior of the drive. With the valves, the closing speed of the drive or an opening damping can be adjusted.

After a certain displacement, which is determined by the arrangement of the sensor and the associated encoder on the spring piston, the hydraulic pump is turned off. The arrangement of a valve in one of the overflow ensures that the hydraulic pressure in the storage space, and thus the spring preload remains.
  • This supported area of the door opening can be selected so that it corresponds to a frequently used door opening angle, for example up to about 85 °.
