Description
Dämpfer für Verdiohter, insbesondere fUr hermetische Kältemittelverdichter Die Erfindung bezieht sich auf die Dämpferausführung fiir Verdichter, insbesondere hermetische Kältmittelverdichter, wobei der Dämpfer aus Einstörmkanal, Dämpferkammer und Ausströmkanal besteht und separat in den Ssug- bzw. Druckleitungen eingebunden ist.Dampers for evaporators, especially for hermetic refrigerant compressors The invention relates to the damper design for compressors, in particular Hermetic refrigerant compressor, the damper from inlet duct, damper chamber and outflow channel and integrated separately in the suction and pressure lines is.
Be ist bekannt, mittels Dämpfer ein interessierendes Frequenzbereich zu bedämpfen, um ein fiir den Betriebszustand des Verdichters vertretbares Geräusch zu erhalten. Diese Forderung wird einesteils dadurch eriüllt, daB die Dämpfer in den Bauteilen des Verdichterblockes eingegossen sind und zum anderen dadurch, daß separate Dämpfer vorgesehen werden.It is known to use attenuators to cover a frequency range of interest attenuated in order to achieve a sound level that is acceptable for the operating state of the compressor to obtain. This requirement is partly fulfilled by the fact that the dampers are in the components of the compressor block are cast and, on the other hand, in that separate dampers can be provided.
Dabei sind die Einzelteile des separaten Dämpfers runde Blechziehteile, die ineinandergesteckt und verlötet werden.The individual parts of the separate damper are round sheet metal parts, which are plugged into each other and soldered.
Es ist auch bekannt, die Einzelteile der separaten Dämpfer U-förmig zu gestalten und so zusammenzubringen, daß eine eder mehrere Kammern entatehen.It is also known that the individual parts of the separate damper are U-shaped to shape and to bring together so that one or more chambers entatehen.
Den bekannten Lösungen haften die Mängel an, daß sie aus relativ teuren Werkstoffen bestehen und hohen aufwand an Lohn und Investitionskosten erfordern.The known solutions have the shortcomings that they are relatively expensive Materials and require high labor and investment costs.
Zweck der Erfindung ist es, die Kosten zur Herstellung von separaten Dämpfern zu senken.The purpose of the invention is to reduce the cost of producing separate Lower dampers.
Aufgabe der Erfindung ist es, Dämpfer durch Einsatz neuer Materialien und rationeller Verarbeitung derselben unter Beibehaltung oder Verbesserung der notwendigen Dämpfungseigenschaften zu schaffen.The object of the invention is to provide dampers by using new materials and more efficient processing thereof while maintaining or improving the to create the necessary damping properties.
Erfindungsgemäß wird dies dadurch erreicht, daß der Dämpfer ganz oder teilweise aus nichtmetallischem, vorzugsweise polymerem Werkstoff besteht. Vorteilhafterweise ist dabei Duro», plast zur Anwendung zu bringen. Eine weitere Ausführungsform ist die teilweise Ausführung des Dämpfers aus nichtmetallisohem, vorzugsweise polymerem Werkstoff. In weiterer Ausgeataltung der Erfindung ist es möglich, den Dämpfer im Spritzgußverfahren herzustellen, wobei die Eingangs-, Überstörm-und Ausgangskanäle mit angeformt werden, die genannten Kanäle dabei in die Kammern hineinragen und dort abgestimmte Längen zum Querschnitt der Kammern haben.According to the invention this is achieved in that the damper completely or partially consists of non-metallic, preferably polymeric material. Advantageously is in the process of applying Duro », plast. Another embodiment is the partial execution of the damper from nonmetallic, preferably polymeric Material. In a further Ausgeataltung the invention, it is possible to use the damper in Manufacture injection molding process, with the input, overflow and output channels are formed with the said channels protrude into the chambers and there have coordinated lengths to the cross-section of the chambers.
Die teohnisoh-ökonomisohen Auswirkungen der Erfindung sind besonders im ökonomischen Materialverbrauch, in den niedrigen Kosten, in der Verringerung des Gesamtgewichtes des Verdiohters bei Beibehaltung oder Verbesserung der Dämpfungseigenschaften des Verdichters, zu sehen.The natural economic effects of the invention are particular in economic material consumption, low cost, reduction the total weight of the Verdiohters while maintaining or improving the damping properties of the compressor.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden. In der zugehörigen Zeichnung zeigen: Fig. 1: einen Dämpfer, vollständig aus nichtmetallischem, vorzugsweise polymerem Werkstoff, wobei die Kanäle angeformt sind.The invention is to be described in more detail below using an exemplary embodiment explained. The accompanying drawings show: FIG. 1: a damper, complete made of non-metallic, preferably polymeric material, the channels being integrally formed are.
Fig. 2: einen Dämpfer, teilweise aus nichtmetallischem vorzugsweise polymerem Werkstoff Der Dämpfer naoh Fig. 1 besteht aus den beiden Dämpferhälften 1 und 2, die nach dem Zusammenbau die Kammer 3 bilden.Fig. 2: a damper, preferably partially made of non-metallic material polymer material The damper according to Fig. 1 consists of the two damper halves 1 and 2, which form chamber 3 after assembly.
An den Dämpferhälften 1 und 2 sind die Ein- und Ausgangsquerschnitte 4 und 5 angeformt, die kit ihren Teilen 4a und 5a in die Kammer 3 ragen.The inlet and outlet cross-sections are on damper halves 1 and 2 4 and 5, the kit parts 4a and 5a protrude into the chamber 3.
Fig. 2 zeigt einen Mehrkammerdämpfer, teilweise in nichtmetallischer, insbesondere aus polymerem Werkstoff bestehender Ausführungsform. Dabei ist die Dämpferkapsel 6 ein Bleehziehteil, welches iit dem Abgangsrohr 7 ist verbunden wird.Fig. 2 shows a multi-chamber damper, partly in non-metallic, in particular embodiment made of polymer material. Here is the Damper capsule 6 is a sheet metal drawn part which is connected to the outlet pipe 7.
In die Dämpferkapsel 6 werden die Einsätze 8 und 9 eingebracht. Damit entstehen die Kammern 10 und 11. Die Verbind dungquerschnitte sind so ausgelegt, daß sie in die Kammern 10 und 11 ragen.The inserts 8 and 9 are placed in the damper capsule 6. In order to chambers 10 and 11 are created. The connection cross-sections are designed so that that they protrude into the chambers 10 and 11.
