Definitions

  • the invention relates to a drive for a wing of a window, a door or the like, with a housing and arranged in the housing, cooperating with an output shaft for opening and closing the wing, acted upon by a spring unit in the closing direction of the piston through which the housing a spring chamber containing the spring chamber and a damping chamber is divided.
  • Drives of the type mentioned are well known. They may for example be designed as overhead door or window drives, which often have a toothed piston, in the toothing meshes a pinion of an output shaft. On the output shaft in a known manner, a linkage or guided in a slide sliding arm is arranged, which cooperates with the wing for opening and closing. The piston is acted upon in the housing filled with hydraulic fluid by a spring. To control the behavior of the drives overflow channels for the hydraulic fluid are arranged with associated valves in the drives. In addition, such drives may for example be designed as a floor spring, which are usually provided with an output shaft with associated Hubkurvenization which engages the fulcrum of the wing.
  • the drives can be purely manual drives or automatic drives, usually electro-hydraulic drives.
  • the EP 2 388 421 A2 and the EP 2 388 422 A2 describe drives, each with different, but based on the selbigen principle, located in the spring chamber of the drive, pressure compensation elements which contain a plurality of chambers in which the gas volume is in spatial communication with the hydraulic fluid, but which does not penetrate into the spring chamber due to the design of the pressure compensation elements can.
  • the invention has for its object to provide a drive of the type mentioned above, which ensures a more reliable pressure equalization with simpler and more cost-effective design.
  • the drive for a wing of a window, a door or the like comprises a housing and disposed in the housing, cooperating with an output shaft for opening and closing the wing, acted upon by a spring unit in the closing direction of the piston, through which the housing into a spring unit containing spring chamber and a damping chamber is divided.
  • the housing is filled with a hydraulic fluid such that a pressure equalization gas volume is left in the spring chamber and hydraulic fluid from the spring chamber can be transferred into the damping chamber only through a sleeve connected to the piston, extending into the spring chamber or a piston rod having at least one outflow channel is, whose cavity or respective outflow channel communicates via at least one inlet opening with the spring chamber.
  • the sleeve or piston rod are arranged in the spring chamber and a respective inlet opening is positioned so that a respective inlet opening of the sleeve or piston rod is completely surrounded by the hydraulic fluid even at the lowest operating temperature of the drive.
  • the volume or pressure compensation is thus effected by the gas volume left in the spring chamber, which is compressible or expandable and compensates for a temperature-induced change in the volume of the hydraulic fluid.
  • the respective inlet opening for the hydraulic fluid in the spring chamber can be positioned so that it is in any position of the drive in the liquid volume.
  • no gas of the gas volume can get into the damping chamber.
  • Particularly suitable is an approximately central positioning of the inlet opening in the longitudinal direction of the spring chamber considered, since then even with any vertically oriented drive, as may occur during transport, no gas enters the damping chamber and a maximum gas volume is possible.
  • the gas volume left in the spring chamber during operation included at least at the commonly occurring operating temperatures. It can thus not get into the damping chamber, which would worsen the damping and would have a so-called falling through the wing result, which must be avoided to ensure reliable operation of the drive. Due to the configuration of the invention, a more reliable pressure equalization is achieved with a simpler and correspondingly less expensive construction.
  • the hydraulic fluid from the spring chamber can only be transferred through the sleeve or piston rod and via the piston into the damping chamber.
  • the piston is designed in particular as a hollow piston, wherein the cavity is in communication with the interior of the sleeve or the discharge channel of the piston rod.
  • overflow channels are provided with associated valves between the cavity of the piston and the damping chamber.
  • the sleeve or a respective outflow channel of the piston rod are arranged in the spring chamber and a respective inlet opening of the sleeve or piston rod positioned so that a respective inlet regardless of the position of the drive, even at the lowest operating temperature of the drive completely from the hydraulic fluid is surrounded.
  • the sleeve or piston rod viewed transversely to the direction of displacement of the piston arranged in particular centrally in the spring chamber and the inlet opening of the piston connected to the piston or piston rod at its initial position eintecdem piston, which occupies this with the wing closed, viewed in the longitudinal direction of the spring chamber in particular at least be arranged substantially in the central region of the spring chamber.
  • the inlet opening of the sleeve or piston rod is always positioned within the spring chamber that they always surrounded regardless of the position of the drive of hydraulic fluid and that due to the lighter specific Weight overhead gas volume is completed, so that an unwanted falling through of the wing is prevented.
  • the pressure compensation function is ensured regardless of the position of the drive.
  • This position independence is important in an alternative mounting on the hinge side or the tape opposite side of a door or in the optional mounting on the wing or on the frame of the door, since the drive must also be mounted rotated by 180 °.
  • the position independence is also advantageous for storage and transport of the drive, wherein the drive can be exposed to different temperatures in different layers.
  • the sleeve or piston rod preferably extends at least parallel to the direction of movement of the piston and / or at least substantially parallel to the central longitudinal axis of the spring chamber.
  • the sleeve or piston rod can extend in particular at least substantially along the central longitudinal axis of the spring chamber.
  • the cavity of the sleeve is preferably connected to the spring chamber via at least one inlet opening provided in the region of the sleeve end facing away from the piston.

  • the piston rod can in particular be provided with a discharge channel extending along its central longitudinal axis.
  • a respective outflow channel extends from the piston only along part of the piston rod.
  • a respective outflow channel communicates with the spring chamber via at least one at least substantially radial inlet opening provided in the region of its end facing away from the piston.
  • the sleeve or piston rod is preferably provided with only one inlet opening for the hydraulic fluid to be transferred from the spring chamber into the damping chamber.

Due to the leak-free volume compensation, a hydraulic opening damping can now be realized, for example, even in the case of a floor-mounted door closer.
  • the filling of the drive while leaving a defined gas volume in the spring chamber can be carried out at any temperature, since the trapped gas volume, in contrast, expands at lower temperatures and is compressed at higher temperatures. It is only necessary to ensure that the respective inlet opening of the sleeve or piston rod for the hydraulic fluid is still surrounded by the hydraulic fluid even at the lowest operating temperature. At higher operating temperatures, the volume of the hydraulic fluid increases, so that the respective inlet opening is enclosed over the entire operating temperature range of the hydraulic fluid and the gas volume is thus reliably closed and can not get into the damping chamber.
