Definitions

  • the invention relates to a valve for driving a door or a window according to the preamble of patent claim 1.
  • a valve which can be fastened in a running with an internal thread bore of a designed as a hydraulic door closer drive.
  • the valve has a base body with a Regulier Scheme and a rotation and a thread.
  • the thread can be arranged in the internal thread of the bore.
  • the anti-rotation device has at least one groove, which is arranged on the thread and receives an elastic element.
  • the disadvantage is the valve consuming to manufacture by grooves must be introduced into the thread for receiving the elastic element. Possibly, after repeated adjustment of the valve, the anti-twisting effect of the elastic element can be reduced by cutting the thread flanks.
  • the invention has for its object to provide a simple and inexpensive to manufacture valve, which is secured against accidental rotation.
  • Drives for doors or windows are known per se and can be designed as manual or automatic drives.
  • a drive comprises a housing having a bore in which a working piston is arranged, which cooperates with an output shaft geared.
  • a linkage or a sliding arm can be arranged rotatably.
  • the Drive can be arranged either on a wing of the door or the window or on their framing. Accordingly, the linkage or the sliding arm is supported on the frame or the wing, whereby a connection between the pivoting movement of the wing and the drive is effected.
  • a spring is further arranged, which is compressed during a rotational movement of the output shaft when manually or when effected by a hydraulic pump, automatic opening of the wing by moving the working piston and serves as an energy storage for automatic closing of the wing.
  • the interior of the housing is divided by the piston into several rooms. Between these spaces hydraulic channels are arranged with associated valves for influencing the overflow, which serve to control the drive behavior.
  • valves are each arranged in a threaded bore in the housing of the drive and are adjusted by rotation, whereby a valve cone of the valve is displaced relative to a arranged in the hydraulic channel valve seat and so the hydraulic channel opens more or less wide or closes.
  • the combination ring which combines two functions.
  • the valve is sealed to the outside, so that no hydraulic fluid can escape and on the other hand, a safeguard against twisting is realized.
  • the combination ring is formed in one piece from a sealing ring and a retaining ring.
  • the locking ring is arranged with respect to the hydraulic channel after the sealing ring, so that the locking ring is arranged in the "dry" region of the valve, whereby a possible reduction of friction between the locking ring and the wall of the drive housing is prevented by hydraulic fluid and a consistently high coefficient of friction is maintained.
  • the combination ring is advantageously molded in a manufacturing process of the valve. This is in addition to the grooves for receiving the seal and the locking ring a recess disposed in the valve, which connects the two grooves and which forms a sprue area for the molding of the combination ring to the valve.
  • a connecting web is thereby formed on the combination ring between the sealing ring and the securing ring, which prevents twisting of the securing ring in particular on the valve body.
  • the drive 1 has a housing 4, in which in known manner, for example, a piston and designed as a spring energy storage are arranged in a filled with hydraulic fluid receiving space.
  • the energy storage is charged by manual or automatic opening of the wing 2 of the door and causes the wing 2 is automatically returned to its closed position after opening.
  • the drive 1 causes the introduction of force to the door via a hinged linkage or via a guided in a slide rail 5 by means of a sliding block slide 6, which or which an output shaft, which is operatively connected to the piston, is arranged rotationally fixed.
  • the housing 4 of the drive 1 may be fixed to the frame 3 or on the wing 2.
  • the linkage or the sliding arm 6 as a force transmission element is supported, depending on the selected arrangement, either on the wing 2 or on the frame 3.
  • valves 8 are arranged, by means of which an overflow of the hydraulic fluid from one piston side to the other to control the behavior of the drive 1 is possible.
  • valves 8 for example, a closing speed, a closing delay, an end impact, which causes the wing 2 safely falls into the lock, or an opening damping adjustable.
  • valves 8 are each arranged in a threaded bore in the housing 4, in which also the valve seat of the associated hydraulic channel 7 is expediently formed.
  • Fig. 2 the arrangement of one of the valves 8 is shown in a partial section of the housing 4.
  • the adjustable by turning valves 8 are to be secured against unintentional rotation and thus unintentional adjustment of the behavior of the drive 1.
  • An anti-twist device is advantageously provided on each valve 8, which is formed in combination with a seal which seals the respective valve 8 to the outside, thereby preventing the hydraulic fluid from exiting the housing 4 of the drive 1.
  • FIGS. 3 to 7 one of the valves 8 is shown in detail.
  • the valve 8 consists of a valve body 9 produced as an injection molded part and a valve cone 10, which may be formed of a material having a particular coefficient of thermal expansion and suitable for compensating for a change in viscosity caused by temperature fluctuations of the hydraulic fluid and thus an otherwise changing behavior of the drive 1 is.
  • the valve cone 10 is advantageously molded onto an extension of the valve body 9.
  • the valve cone 10 may also consist of the same material as the valve body 9, wherein valve body 9 and valve plug 10 are then formed in one piece.
  • the valve body 9 is provided for receiving in the threaded bore of the housing 4 with a thread 11, whereby the valve 8 is received adjustably by screwing in the housing 4.
  • the valve body 9 has a tool holder 12, for example, for a screwdriver or the like on.
  • two annular grooves 13, 14 are provided and a substantially perpendicular to the grooves 13, 14 arranged recess 15, which connects the grooves 13, 14.
  • a combination ring 16 is arranged, which combines the sealing function and the rotation in itself.
  • valve 8 is shown in an oblique pattern as an exploded view, wherein the three elements valve body 9, valve cone 10 and combination ring 16 of the valve 8 are shown individually. If the valve body 9 and the valve cone 10 are integrally formed, then the valve 8 together with the combination ring 16 is formed only from two elements. The combination ring 16 is advantageously molded directly onto the valve body 9 as the last manufacturing process.
  • the combination ring 16 produced by means of the injection process is formed in one piece and consists of the thinner circlip 17, which is received in the groove 13 and the thicker sealing ring 18, which is received in the groove 14.
  • the formed as a common sprue connecting web 19 is provided in the region of the recess 15, through which the combing ring 15 forming material flows into the groove 13 and into the groove 14 during the injection process.
  • the sealing ring 18 is thereby formed by the - not shown here - injection molding tool so that it is spaced from the flank 21 of the groove 14, which gives sufficient space for elastic deflection of the sealing ring 18 during its deformation in the receptacle in the housing 4 of the drive 1 is.
  • sealing region of the sealing ring 18 is positioned spaced from the flank 20, wherein the material approach 22nd is lower than the sealing ring 18 and remains below the flank 20, whereby in the direction of the flank 20 sufficient space for elastic deformation of the sealing ring 18 is given.
  • the recess 15 is tapered in the direction of the groove 13 in order to influence the flow of material, wherein the to be triggered in the groove 13 retaining ring 17 is substantially thinner than the in the groove 14 to be sprayed sealing ring 18.
  • the arranged in the recess 15 connecting web 19 advantageously prevents rotation on the valve body 9, in particular the locking ring 17, which cooperates with the valve 4 screwed in the housing 4 rotationally locking with the wall of the bore in the housing 4 and so unintentional rotation and thus unintentional adjustment of Valve 8 prevents.
  • the sealing ring 18 seals the hydraulic fluid to the outside. Since the locking ring 17 is advantageous outside in the sealed, dry area of the bore, a high uniform braking effect is achieved by friction between the locking ring 17 and the wall of the housing 4. The sealing ring 18 contributes only slightly to an anti-rotation, since a partial wetting by hydraulic fluid is possible.
