Definitions

  • the invention relates to a door closer according to the preamble of the claim 1.
  • the door closer has a housing in which a piston is guided linearly displaceable.
  • One designed as a closing spring mechanical energy storage acts for automatic Closing the door leaf on a driven member designed as a closer shaft, on which a force-transmitting linkage can be connected.
  • a hydraulic damping device causes a muted closing of the door leaf, wherein the housing interior is filled with a damping medium and the piston the housing interior liquid-tight in two housing chambers divided.
  • FIG. 1 An embodiment of the o.g. DE-OS (FIG. 1 there) shows a separate arrangement of overflow valve and pressure relief valve in the piston. This embodiment is time-consuming and expensive to manufacture, as in the piston several Holes must be introduced and the valves are mounted separately.
  • FIG. 2 shows a piston with a frontally mounted on the piston cap-shaped molding, in which a combined valve (combination of non-return valve and pressure relief valve) is arranged.
  • This embodiment is in the production time and Costly because the manufacture and assembly of a separate molding is required for receiving the valve and the piston for mounting the Must be pretreated molding (twisting the piston to create a smaller cross section in the region of the molded part, additional bore for preventing rotation).
  • the invention is based on the object, a door closer with pressure relief valve to create, which is easy and inexpensive to produce.
  • the designed as a combination of overflow valve and pressure relief valve has a directly slidably guided guided in a piston bore of the piston Valve body on.
  • the piston therefore only a single hole are introduced for receiving the valve, and the inner surface of the piston bore acts directly on the valve body and its seal together, thereby additional items are saved; both lower the production costs clear.
  • the valve can be completely pre-assembled outside the piston: into the valve body can after inserting the valve plug and a spring a valve core be inserted, with the connection between the valve core and valve body can be designed as a latching connection. This too leads to a serious Simplification of assembly and thus to a further reduction of Production costs.
  • the pre-assembled valve can finally in a very simple way, namely latching be inserted into the piston bore.
  • the valve can also be modular: it can be a single, uniform trained valve body provided to cover all applications be.
  • this valve body can be varied, the particular application adapted parts, in particular different valve inserts and / or different springs and / or different valve cone, be used.
  • the springs can be different depending on the response pressure of the pressure relief valve be long, with a suitable valve insert for each spring length can be provided. Leave through this modular construction of the valve the production costs, in particular tool and / or storage costs lower further.
  • valve body e.g. the valve body, the valve core and / or the poppet
  • various components of the valve e.g. the valve body, the valve core and / or the poppet
  • plastic injection molding
  • the door closer 1 shown in FIG . 1 has a housing 2 with a piston 3 guided linearly displaceably therein.
  • the piston 3 is provided in its interior with a toothing 8, in which the gear 9 of the housing 2 of the door closer 1 rotatably mounted closer shaft 10 meshes.
  • a closing spring designed as a helical compression spring 7 is arranged in the left housing chamber 6 and acted upon - on the housing, for example on the left housing closure not shown here - supporting the piston 3 in the illustrated right position. This position corresponds to the closed position of the door leaf, which is connected to the closer shaft 10 of the door closer 1 via a force-transmitting linkage, such as scissor arm or sliding arm, or directly.
  • valve 15 As soon as the door leaf is released, the compressed closing spring presses the piston 3 to the right; the closer shaft 10 is in this case counterclockwise rotated, leaving the connected door in its closed position is transferred. Since the valve 15 at the now in the right housing chamber 4 existing pressure is closed, flows through the damping medium an overflow channel, not shown here, which is also not shown Valve for ensuring the closing dampening contains steamed in the left housing chamber 6 or in the piston interior 5. This ensures that the door does not close abruptly, but muffled in its closed position is transferred. Will the door wing during the muted Closing operation manually overruled, i. the door is closed faster, as it provides the closing damping actually, it is now under stronger Overpressure standing damping medium from the right housing chamber. 6 discharged through the valve 15 in the piston interior 5. The valve 15 is so formed that it only at a relatively large overpressure in the right housing chamber 6, which arises when manually overpressing the door leaf, opens while it is closed during normal damped closing of the door leaf is.
  • FIG. 2 shows a section of the piston 3 in the region of its right-hand end side.
  • the valve body 18 of a valve 15 designed as a combination valve is arranged in a frontal piston bore 14.
  • a valve insert 25 is arranged within the valve body 18.
  • a supported in the valve insert 25, designed as a helical compression spring spring 27 acts on a linearly displaceable poppet 24 against a present in the right end of the valve body 18 bore 23.
  • the valve insert 25 also has on its left front side a bore 28 to the piston interior 5.
  • the valve body 18 of the valve 15 is linearly displaceable within the piston bore 14 arranged.
  • the figure shows the valve body 18 in its left End position.
  • One attached to the valve body 18 liquid-tight, as a ring seal formed seal 19 is in this end position of the valve body 18 tight a depression 16 of the piston bore 14 at.
  • the valve body 18 takes this position in the case of the damped closing process resulting overpressure of Damping medium in the right housing chamber 4 a. That under pressure standing damping medium urging through the bore 23 of the valve body 18th against the spring-loaded valve cone 24.
  • the seal 19 may be more or less compressed if necessary.
  • the valve body 18 is designed so that it is at very high pressure in the right housing chamber 4 against the countersink 16 of the piston bore 14 pushes.
  • a filter disk 22 is arranged in the valve body 18, which optionally present in the flowing-through damping medium Foreign body absorbs.
  • valve body 18 To the right, the sliding movement of the valve body 18 by locking tongues 20 limited, which engage in a recess 17 of the piston bore 14.
  • the valve body 18 takes this position at positive pressure in the piston interior 5 on. Characterized in that the seal 19 in this position of the valve body 18th is no longer in contact with the countersink 16 of the piston bore 14, the Damping medium from the piston interior 5 through the channels shown in Figure 4 flow undamped into the right housing chamber 4. The to the door closer 1 connected door can thus be undamped against the force of the closing spring be opened.
  • valve 15 shown in Figure 3 works identically as described in the previous embodiment. Modified over the previous embodiment, the attachment of the valve insert 25 in the valve body 18.
  • the valve body 18 has recesses 21, in which latching cam 26 of the valve insert 25 engage latching.
  • FIG. 4 shows a cross section through the valve body 18.
  • the valve body 18, which is actually round in cross section, has flattenings 29 which form channels with a flow cross section 30 with the inner wall of the piston bore 14. These channels are traversed by flowing from the piston interior 5 in the right housing chamber 4 damping medium.
