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 is known, with a housing and a housing arranged in the spring-loaded piston, the housing is filled with a hydraulic fluid, which serves to control the piston movement during opening and closing of the wing, including upper flow and Valves are provided.
  • a hydraulic fluid which serves to control the piston movement during opening and closing of the wing, including upper flow 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 door closer doing a acted upon a spring piston is guided.
  • 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.
  • 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 directed into the interior of the differential housing in sleeve.
  • the pressure compensation device is filled with hydraulic fluid to the extent that the inner opening of the sleeve is always covered by hydraulic fluid.
  • the sleeve advantageously extends to the middle of the volume center of the differential housing or slightly beyond.
  • a gas volume is included in the pressure compensation device. Since gases are compressible or expandable are, 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 mounting 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 sleeve, 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.
  • the sleeve is temporarily closed in the interior of the differential housing of the pressure compensation device with a stopper. After filling the differential housing with hydraulic fluid while keeping the gas volume free through a designated filling opening in the differential housing, this opening is closed with a closure element.
  • 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 drive housing is closed.
  • a pressure increase in the drive can now be effected, which acts through the sleeve on the plug and lifts it from the sleeve, 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 displaceably guided in the cylindrical interior piston 3, in the toothing of the pinion of the 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 cylindrically shaped pressure compensation device 8 is arranged, wherein the pressure compensation device 8 may be fixed to the housing cover (7) or formed integrally therewith.
  • 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.
  • valves and check valves 10 is a controlled Overflow of hydraulic fluid 9 between the chambers of the housing 2 possible. It is also possible to connect a hydraulic pump (not shown here) to a suitable overflow channel, whereby an automatic operation of the drive 1 is possible by using control elements for detecting persons.
  • the drive 1 is shown with the housing 2 with the pressure compensation device 8 arranged in the drive 1 and the hydraulic fluid 9 located therein in each case 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 the 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 is partially filled with hydraulic fluid 9, wherein the filling opening is closed with a closure element 15.
  • the interior of the differential housing 11 of the Druckaus GmbHseinrichtüng 8 is not completed with respect to the interior of the housing 2 of the drive 1, but is by means of a sleeve 12 with this in conjunction, wherein the sleeve 12 extends at least to the center of the differential volume of the differential housing 11. It is conceivable to carry out the filling with hydraulic fluid 9 through the filling opening in the housing 2 of the drive 1, the hydraulic fluid 9 flowing through the sleeve 12 into the differential housing 11 of the pressure compensation device 8 and venting through the opening in the differential housing 11.
  • the pressure compensation device 8 can also be prefilled introduced into the housing 2 of the drive 1.
  • the filling with hydraulic fluid 9 is carried out so that the housing 2 contains no more air or gas, as this, as described above, leads to a "falling through” of the drive 1.
  • the level of the hydraulic fluid 9 in the differential housing 11 is to be chosen so that at a lowest intended operating temperature, the sleeve 12 is at least just completely surrounded with hydraulic fluid 9, as shown in the Fig. 2 is shown.
  • the gas volume 14 is thereby completed in the differential housing 11.
  • the drive 1 and the hydraulic fluid 9 may have this temperature during filling. If the filling is carried out at a higher temperature, the amount of hydraulic fluid 9 must be calculated. If the temperature drops compared to the temperature during filling, the gas volume 14 is expanded, and it is also achieved a pressure equalization.
  • a filling can thus take place at ambient temperature.
  • 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 gas volume 14 has been compressed and this captured the pressure increase in the drive 1 Has.
  • Fig. 4 the state is shown after a further increase in temperature, whereby a further compression of the gas volume 14 is carried out.
  • a gas volume 14 remains in the pressure compensation device 8, which may be the ambient air, which was also in the drive 1 with the pressure compensation device 8 before filling. 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 forms the gas volume 14 after filling.
  • the sleeve 12 of the pressure compensation device 8 may have a throttle 13, which dampens the overflow of the hydraulic fluid 9 into and out of the differential housing 11, whereby operational short-term pressure increases in the drive 1, the desired, functionally induced overflow of the hydraulic fluid 9 via the valves and Overflow channels cause, are not compensated, but only slow pressure changes, as done by the action of the ambient temperature on the drive 1.
  • FIGS. 5 and 6 it is in the FIGS. 5 and 6 in each case from left to right, the drive 1 shown at different temperatures.
  • the drive 1 In the illustration on the left, the drive 1 is shown at the lowest permissible temperature, wherein the sleeve 12 just completes the gas volume 14.
  • the middle figure In the middle figure is a volume expansion of the hydraulic fluid 9 by increasing the temperature with concomitant compression of the gas volume 14 and in the right figure, a corresponding state is shown at even further increase in temperature.
  • FIG. 7 shows a skew of the drive 1 of each in the FIGS. 5 and 6 left illustrated state of the drive 1 at the lowest permissible temperature. Even with an inclined position of the drive 1, the gas volume 14 remains conditionally closed by the sleeve 12 within the pressure compensation device 8.
  • FIG. 8 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 sleeve 12 is closed within the pressure compensation device 8 with a stopper 17 and then filled with an amount of hydraulic fluid 9 - corresponding to the temperature prevailing during filling - and sealed with the closure element 15. Above the hydraulic fluid 9 is then the required gas volume 14.
  • the housing 2 of the drive 1 is acted upon by a vacuum 18, as shown in the left figure in the Fig. 8 is shown. After the evacuation, the hydraulic fluid 9 flows directly, for which purpose the vacuum device is formed.
