Definitions

  • the invention relates to a valve for a drive of a wing of a door or a window according to the preamble of claim 1.
  • a drive for the wing of a door with a housing and filled with a hydraulic fluid receiving space.
  • the drive has in the receiving space a against the force of a spring slidably mounted piston, which cooperates with an output shaft for wing operation.
  • In the drive housing further bores are arranged, which allow an overflow of the hydraulic fluid from one piston side to the other.
  • a valve for throttling the flow velocity in the closing and in the opening direction is arranged in these hydraulic channels.
  • the GB 2 193 757 A discloses a door closer, with a piston, which is displaceably guided in a piston chamber filled with a hydraulic fluid, and with a further space in which a compressible airbag is as energy storage.
  • the piston chamber and the other space are connected by hydraulic channels, in which valves are arranged to control the door closer.
  • valves require multiple holes, and a larger housing is required for space.
  • EP 1293633A2 shows a door closer with a housing, a linearly displaceably guided in the housing piston and a hydraulic damping device, wherein the housing interior is filled with a damping medium, and wherein the housing interior is liquid-tightly divided by the piston in at least two housing chambers.
  • an overflow valve and an additional pressure relief valve arranged, which is effective in a resulting by manual overpressure of the door in the closing direction overpressure of the damping medium in a housing chamber by the damping medium drains in addition to the damping device via the pressure relief valve from the housing chamber.
  • the pressure relief valve and the spill valve are combined in a valve body of a valve disposed in a piston bore of the piston, wherein the valve body is slidably guided in the piston bore, and having a seal which cooperates directly with the inner surface of the piston bore by the valve body in a End position of its displacement area liquid-tight against the inner surface of the piston bore seals.
  • the DE 100 46 914 A1 shows a hydraulic arrangement for actuating moving parts on vehicles, such as rear covers or covers, with a double-acting hydraulic working cylinder for the moving part, a pump for the hydraulic medium, a valve-nozzle arrangement for controlling the pressure build-up in the system and a second valve Nozzle arrangement for the alternative control of the two working chambers of the working cylinder and with a tank for the hydraulic medium.
  • a hydraulic arrangement for actuating moving parts on vehicles such as rear covers or covers
  • a double-acting hydraulic working cylinder for the moving part
  • a pump for the hydraulic medium a valve-nozzle arrangement for controlling the pressure build-up in the system
  • a second valve Nozzle arrangement for the alternative control of the two working chambers of the working cylinder and with a tank for the hydraulic medium.
  • the invention has for its object to produce a cost-effective valve assembly.
  • a hydraulic door operator has a piston, which is arranged in a housing and acted on by a spring, which cooperates with a shaft on which a lever for actuating a door is arranged.
  • the lever When opening the door, the lever is actuated, and stretched over the shaft and the piston, the spring applied to the piston.
  • an electro-hydraulic actuator may be provided to allow a motorized opening of the wing.
  • the hydraulic fluid in the housing must flow over the hydraulic channels and valves from one side of the piston to the other as the piston chambers on both sides of the piston change as a result of its displacement. In this case, the slightest possible overflow of the hydraulic fluid is made possible when opening the door in order to achieve an unrestrained operation of the door.
  • two valves are arranged so that a second valve is located in a first valve.
  • a valve seat is formed, which is associated with the first valve.
  • the hydraulic fluid can flow from one hydraulic channel into another hydraulic channel.
  • sealing elements are arranged on the valve body, which seal the valve to the outside against the housing and against not the valve associated hydraulic channels.
  • the valve body is arranged in a bore in the housing, in which a thread is introduced, whereby the valve passage can be adjusted by turning with a tool.
  • the second valve is arranged to save space in the first valve.
  • a thread is present in the valve body of the first valve, in which the valve body of the second valve is adjustably received.
  • a seal is arranged, which seals the valve body to the outside against the valve body of the first valve.
  • a valve seat is formed, which cooperates with the valve body of the second valve.
  • the first valve has recesses, through which hydraulic fluid passes to the second valve, and can flow over the valve seat.
  • the valves may each have a passageway that allows a forced flow when the valve is closed, so that the respective function of the drive is not completely blocked.
  • a section of a housing 1 of a door drive is shown in a sectional view.
  • hydraulic channels 2, 2 ', 2 ", 2'” are arranged, which allow an overflow of hydraulic fluid.
  • the overflow can be regulated to control the door drive by valves 5, 6 arranged in the hydraulic passages 2, 2 ', 2 ", 2'".
  • a connection 17 for connecting a hydraulic pump can be present on the hydraulic channel 2 '.
  • 6 are arranged so that a valve body 6 'of the second valve 6 in a valve body 5' of the first valve. 5 located.
  • a valve seat 10 associated with the valve 5 is formed in the housing 1.
  • the hydraulic fluid can flow into the hydraulic passage 2 'can be arranged on the valve body 5', which allows a forced flow when the valve 5 is closed, so that the drive is not completely blocked with a counterforce on the wing.
  • valve body 5 'sealing elements 9, 9' are arranged, which seal the valve 5 against the housing 1.
  • the sealing element 9 seals the hydraulic channels 2 "and 2 '" against each other.
  • the sealing element 9 'seals the hydraulic channel 2'"outwards, the valve body 5 'being in a bore in the housing 1 arranged, in which a thread 7 is introduced.
  • the valve 6 is arranged to save space in the valve 5.
  • a thread 12 is present in the valve body 5 ', in which the valve body 6' is adjustably received.
  • the valve 6 in the valve body 6 ' also, for example, a slot 16 for engagement of a tool.
  • a valve seat 14 is formed, which cooperates with the valve body 6' and forms the valve 6.
  • the valve body 5 ' has recesses 8 through which hydraulic fluid can flow from the hydraulic channel 2' "to the valve 6 and can flow over into the channel 2 'via the valve seat 14.
  • valve body 6 It is likewise possible to form a flow channel 11 on the valve body 6', which allows an overflow of hydraulic fluid even when the valve 6 is completely closed, and the flow passage 11 can also be formed on the valve seat 14 of the valve body 5.
  • the valve 6 has on the valve body 6 'a sealing element 13 which seals the valve 6 to the outside.
  • the thread 7, in which the valve body 5 'is rotatably arranged can have a smaller pitch than the thread 12 in which the valve body 6 'of the valve 6 is arranged.
  • the larger passage cross section of the outer valve 5 can be compensated.
  • valve body 5 does not adjoin an adjustment operation of the valve 6.
  • the valve body 6 rotates in the valve body 5', so that the valve body 6 'remains unchanged in its position in the valve body 5'.
  • the adjustability of the valves can also be influenced. This is the adjustability the adjustment of the respective other valve 6, 5.
  • the setting can also be achieved or supported by different pitches of the thread 7, 12.
