Description

Verdichter mit geräuschdämpfenden Kammern Die Erfindung betrifft einen Verdichter, insbesondere für Kältemaschinen, der vorzugsweise in seinem im Verdiehtergehäuse verlaufenden Ansaugkanal mindestens zwei zur Geräuschdämpfung vorgesehene erweiterte Kammern hat, die auf ihrem äußeren Ende durch einen gemeinsamen Deckel verschlossen und durch engere Bohrungen miteinander verbunden sind.Compressor with noise-damping chambers The invention relates to a Compressor, in particular for refrigeration machines, which is preferably in its in the Verdiehter housing extending intake duct extended at least two provided for noise damping Has chambers, which are closed on their outer end by a common lid and are connected to one another by narrower bores.

Bekannte Kammern dieser Art sind miteinander durch enge Bohrungen verbunden, die entsprechend dem in Fig. 1 der Zeichnung dargestellten Beispiel von dem äußeren, offenen Ende der erweiterten Kammern a oder b her gebohrt worden sind. Auf diese Weise können nur wenig schräg liegende Bohrungen angebracht werden, da der verhältnismäßig dünne Bohrer, der an der oberen Kante der betreffenden Kammer vorbeigeführt werden muß, nur dann an der Kammerwand angreift, wenn er beinahe senkrecht zu dieser Wand angesetzt wird. Mit derartigen Kammerverbindungen kann das Kältemittel nur in geringem Maße umgelenkt werden, so daß eine geringe Geräuschdämpfungswirkung eintritt. Die in der genannten Weise verlaufenden engeren Bohrungen lassen sich außerdem schlecht anbringen.Known chambers of this type are connected to one another by narrow bores which, according to the example shown in FIG. 1 of the drawing, have been drilled from the outer, open end of the enlarged chambers a or b. In this way, only slightly inclined holes can be made, since the relatively thin drill, which must be guided past the upper edge of the chamber in question, only engages the chamber wall when it is placed almost perpendicular to this wall. With such chamber connections, the refrigerant can only be deflected to a small extent, so that a low noise dampening effect occurs. The narrower bores running in the manner mentioned are also difficult to make.

Die Erfindung vermeidet die genannten Schwierigkeiten dadurch, daß von dem zwischen den beiden Kammern sich erstreckenden Abschnitt der Gehäuseauflagefläche für den Deckel ausgehend, zwei an ihrem Anfang verbundene Schrägbohrungen vorgesehen sind, von denen die eine in die erste und die andere in die zweite Kammer, und zwar jeweils in der Nähe des inneren Endes der Kammern münden.The invention avoids the difficulties mentioned in that from the portion of the housing support surface extending between the two chambers starting for the cover, two inclined bores connected at their beginning are provided are, of which one in the first and the other in the second chamber, namely each open near the inner end of the chambers.

Ein Ausführungsbeispiel der Erfindung ist in der Fig.2 der Zeichnung dargestellt, die einen Teillängsschnitt durch den Zylinderraum und die Druck-und Saugkammern eines Kältemittel-Verdichters zeigt.An embodiment of the invention is shown in Figure 2 of the drawing shown showing a partial longitudinal section through the cylinder space and the pressure and Shows suction chambers of a refrigerant compressor.

Das Gehäuse 1. des Verdichters ist ein Gußteil, in dem der Zylinder 2 mit dem Kolben 3 und zwei an der Saugleitung 4 vorgesehene, erweiterte, der Geräuschdämpfung dienende Kammern 5 und 6 angeordnet sind. Diese Kammern sind an ihrem äußeren Ende durch einen mit einer Dichtung 7 versehenen gemeinsamen Deckel 8 abgeschlossen. Von der Mitte der zwischen den beiden Kammern 5 und 6 liegenden Gehäuse-Auflagefläche 9 für den Deckel gehen zwei an ihrem Anfang verbundene Schrägbohrungen 10 und 11 aus, von denen die erste, 10, in die erste Kammer 5 und die zweite, 11, in die zweite Kammer 6, und zwar jeweils in der Nähe des inneren Endes jeder Kammer münden. Derartige Schrägverbindungen können leicht gebohrt werden. Sie lenken außerdem das Kältemittel sehr stark um und verstärken dadurch die Geräuschdämpfung.The housing 1. of the compressor is a cast part in which the cylinder 2 with the piston 3 and two provided on the suction line 4, extended, the noise damping serving chambers 5 and 6 are arranged. These chambers are at their outer end closed by a common cover 8 provided with a seal 7. From the center of the housing support surface between the two chambers 5 and 6 9 two inclined bores 10 and 11 connected at their beginning go for the cover of which the first, 10, into the first chamber 5 and the second, 11, into the second Chamber 6, each opening near the inner end of each chamber. Such Diagonal connections can be easily drilled. They also direct the refrigerant very much and thereby increase the noise attenuation.

Die Dämpfungskammern können auch in der Druckleitung oder in der Druck- und in der Saugleitung angeordnet sein.The damping chambers can also be in the pressure line or in the pressure and be arranged in the suction line.
