Definitions

  • the invention relates to a drive for a wing of a door or a window according to claim 1.
  • a drive for a wing of a window or a door comprising a housing and a spring-loaded piston arranged in the housing.
  • the housing is filled with a hydraulic fluid, which serves to control the piston movement when opening and closing the wing, including overflow and valves are provided.
  • a gas volume enclosed by an elastic enveloping body is provided, on the lateral surface of which the pressure of the hydraulic fluid acts.
  • a disadvantage is the complex sealing of the elastic enveloping body, which could possibly also be leaking due to aging.
  • the invention has for its object to provide a simple, reliable pressure compensation device for a drive for a wing of a door or a window.
  • Actuators for wings of a door or a window are well known. These can be designed as floor door closers, which are usually provided with a Hubkurvenization with an output shaft which engages the fulcrum of the wing. In the filled with a hydraulic fluid housing of the Matschlie- ⁇ ers while an acted upon a spring piston is guided. Furthermore, the drives can be designed as overhead door or window drives, which often have a toothed piston, in the toothing of a pinion of an output shaft meshes. 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 also loaded in the filled with the hydraulic fluid housing with a spring. Furthermore, overflow channels and valves for the hydraulic fluid are arranged in the drives, which serves to control the behavior of the drives.
  • the drives can be purely manual drives, but also automatic drives, usually electro-hydraulic drives, which can be designed without a closing spring.
  • the pressure compensation device consists of a differential housing with a channel which is directed into the interior of the differential housing.
  • the channel is arranged in a weight-formed region of the differential housing.
  • the channel is the interior of the differential housing in which there is a gas volume, with the interior of the housing of the drive in connection.
  • the pressure compensation device floats in the housing of the drive existing hydraulic fluid, wherein the pressure compensation device, due to the weight, always rotates so that the channel is directed downward, whereby no gas can escape from the pressure compensation device.
  • the gas volume is thus included in the pressure compensation device. Since gases are compressible or expandable, a temperature-induced change in the volume of the hydraulic fluid is compensated.
  • the pressure compensation device acts independently of position, whereby the drive is suitable for alternative installation methods. 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 pressure compensation device has inexpensive no moving parts or special sealing surfaces and can be produced as a simple casting.
  • a throttle may be provided in the channel, whereby the pressure compensation device is effective only at slow pressure changes, and rapid pressure changes, such as may occur during operation of the door drive, are not compensated.
  • the pressure compensation device allows for a vacuum filling of the drive. After filling of the differential housing with hydraulic fluid while keeping the volume of gas through the channel, this is temporarily closed with a stopper.
  • the filling of the drive is then carried out in a known manner by the housing of the drive is first evacuated and then filled into this vacuum into it with hydraulic fluid. This achieves the best possible gas-free drive interior. After filling the drive, the filling opening of the housing is closed.
  • a temperature increase can now be a pressure increase in the Actuator can be effected, which acts through the channel on the plug and lifts it from the channel, whereby the pressure compensation device is effective.
  • the filling of the pressure compensation device can be carried out at any temperature, since the trapped gas volume, in contrast, expands at lower temperatures and is compressed at higher temperatures, whereby the pressure compensation by the gas volume is effective in each case.
  • the pressure compensation device is not limited exclusively to door closer, but can also be used for example in hydraulic locking devices for door application.
  • Fig. 1 is designed as a door closer drive 1 is shown in section.
  • the drive 1 comprises a housing 2 with a displaceable in the cylindrical interior guided piston 3, in the toothing of a pinion of an output shaft 4 meshes.
  • the drive 1 may also be a drive 1 having a cam or cam disk.
  • a closing spring 5 is arranged axially between an end face of the piston 3 and a housing cover 7 serving at the right end of the housing 2 for closing the housing 2.
  • a housing cover 6 is provided at the end of the housing 2.
  • a plurality of spherical pressure compensation devices 8 are arranged in the cavity within the closing spring 5 .
  • the cylindrical interior of the housing 2 is divided by the piston 3 into two chambers.
  • the left chamber is therefore limited by the housing cover 6 and the piston 3, the right chamber of the piston 3 and the housing cover 7.
  • the chambers are completely filled with hydraulic fluid 9, since the hydraulic system of the drive 1 was vented during filling.
  • the piston 3 can perform its sliding movement in the housing 2 under damping by the hydraulic fluid 9, not shown in the housing 2
  • Matterströmkanäle are formed with associated adjustable valves.
  • 3 check valves 10 are arranged in the piston, which allow directional overflow of hydraulic fluid 9.
  • a controlled overflow of hydraulic fluid 9 between the chambers of the housing 2 is possible.
  • the drive 1 with the housing 2 with a pressure compensation device 8 arranged in the drive 1 and the hydraulic fluid 9 located therein are each shown as a schematic diagram.
  • the functional elements of the drive 1, such as piston 3, output shaft 4 and spring 5 and possibly other elements that may be arranged in the drive 1, not shown, since these are not essential for the description of the function of the pressure compensation device 8 in the drive 1 are.
  • Fig. 2 the drive 1 with the housing 2 and with a single pressure compensation device 8 is shown.
  • the housing 2 of the drive 1 is filled with the hydraulic fluid 9, wherein the filling opening is closed with the closure element 16.
  • the closure element 16 may be arranged in the housing cover 7, or the housing cover 7 itself may be the closure element 16.
  • the pressure compensation device 8 has a differential housing 11 and a channel 12, which is arranged in a designed as a weight 15 region of the differential housing 11. Via the channel 12, the interior of the differential housing 11 is in communication with the interior of the housing 2 of the drive 1, in which the gas volume 14 is located.
  • the weight 15 may be formed integrally with the differential housing 11.
  • the filling of the drive 1 with hydraulic fluid 9 takes place through the filling opening in the housing 2 of the drive 1 and is carried out such that the housing 2 no longer contains any air or gas, since, as described above, this leads to a "falling through” of the drive 1 ,
  • the filling takes place at the lowest intended operating temperature, wherein the pressure compensation device 8 is completely surrounded by hydraulic fluid 9 and the gas volume 14 is thereby completed in the differential housing 11, as shown in the Fig. 2 is shown.
  • the gas volume 14 always remains within the differential housing 11 of the pressure compensation device 8.
  • FIG. 3 a further state of the arrangement, wherein a temperature increase over the lowest operating temperature exists.
  • the hydraulic fluid 9 has expanded due to this increase in temperature, whereby the hydraulic fluid has flowed into the interior of the pressure compensation device 8 and the gas volume 14 has been compressed.
  • the temperature-induced pressure increase in the drive 1 was collected.
  • Fig. 4 the state is shown after a further increase in temperature, whereby a further compression of the gas volume 14 is carried out.
  • the gas volume 14 in the pressure compensation device 8 may be the ambient air, which was before filling in the drive 1 and also in the pressure compensation device 8. It is conceivable, however, prior to filling with hydraulic fluid 9, another gas, such as nitrogen, which behaves advantageous with respect to the hydraulic fluid 9 to introduce, so that this gas after filling the drive 1, the gas volume 14 forms.
  • a throttle 13 may be provided, which dampens the overflow of the hydraulic fluid 9 in the differential housing 11 and out of it, whereby operational short-term Pressure increases in the drive 1, which cause a deliberate, functionally caused overflow of the hydraulic fluid 9 via the valves and overflow, are not compensated, but only slow pressure changes, as done by the action of the ambient temperature on the drive 1.
  • the channel 12 of the pressure compensation device 8 Due to the weight 15, the channel 12 of the pressure compensation device 8 always turns down, whereby an outlet of the gas volume 14, which has a lower density compared to the hydraulic fluid is prevented by the channel 12 out, as in the Fig. 5 is shown.
  • the trapped in the pressure compensation device 8 gas volume 14 is completed by the arrangement of the channel 12 in the weight 15 of the differential housing 11 regardless of position always in the differential housing 11.
  • FIG. 6 the procedure for a vacuum filling of the drive 1 is shown.
  • a vacuum filling is advantageous in order to eliminate as far as possible all air which is located in cavities, undercuts of the functional elements and the overflow channels of the drive 1 from the housing 2.
  • the pressure compensation device 8 is filled with an amount of hydraulic fluid 9 - corresponding to the temperature prevailing during the filling - via the channel 12, which is then closed with a plug 17.
  • the required gas volume 14 is then above the hydraulic fluid 9.
  • the housing 2 of the drive 1 is subjected to a vacuum 18, as shown in the left figure in the Fig. 6 is shown. After the evacuation, the hydraulic fluid 9 flows directly, for which purpose the vacuum device is formed.
  • the housing 2 is now closed by means of the closure element 16, as shown in the Fig. 6 shown in the middle picture.
  • a pressure increase in the housing 2 of the drive 1 for example by increasing the temperature, the plug 17 is pushed out of the channel 12, whereby the pressure compensation device 8 is effective, as shown in the Fig. 6 shown in the right figure.
