Gehäuse für einen an einen Verdichter anschließbaren Schall¬ dämpferHousing for a silencer that can be connected to a compressor
Die Erfindung bezieht sich auf ein Gehäuse für einen an einen Verdichter, insbesondere Seitenkanalverdichter, anschließba¬ ren Schalldämpfer, in dessen Ein- und Auslaßεtrecke Schall- dämpfungsteile angeordnet sind.The invention relates to a housing for a muffler that can be connected to a compressor, in particular a side channel compressor, and in whose inlet and outlet section sound-absorbing parts are arranged.
Ein Schalldämpfer mit einem solchen Gehäuse iεt bei einem durch die DE-C-29 04 975 bekannten Seitenkanalverdichter vor¬ gesehen. Der Schalldämpfer iεt dort mit seiner Anschlußseite stumpf an die entsprechenden Öffnungen des Seitenkanal- verdichtergehäuses angeschlossen. Daher kann bei diesemA silencer with such a housing is provided in a side channel compressor known from DE-C-29 04 975. The muffler is butt-connected there with its connection side to the corresponding openings in the side channel compressor housing. Therefore, with this
Schalldämpfer auf seiner Anεchlußεeite eine genügend große Öffnung für daε Einbringen der Dämpfungsteile in das eintei¬ lig ausgebildete Schalldämpfergehäuse vorgesehen werden. Soll ein Schalldämpfer mittels an seinem Gehäuse vorgeεehener An- schlußεtutzen mit entεprechenden Anεchlußεtutzen des Seiten- kanalverdichterε verbunden werden, dann ergeben εich gegen¬ über der Weite des Schalldämpferinnenraumes kleinere Öffnun¬ gen nach außen, über die die Dämpfungsteile nicht mehr einge¬ bracht werden können.A sufficiently large opening for introducing the damping parts into the one-piece muffler housing can be provided on its connecting side. If a muffler is to be connected to corresponding connecting sockets of the side-channel compressor by means of connection sockets provided on its housing, then there are smaller openings to the outside compared to the width of the muffler interior, through which the damping parts can no longer be introduced.
Der Erfindung liegt die Aufgabe zugrunde, ein Gehäuse für einen Schalldämpfer zu εchaffen, in 'das unabhängig von der Größe der Anεchlußöffnungen des Schalldämpferε die Dämpfungε- teile einbringbar sind.The invention has for its object to εchaffen a housing for a muffler in 'regardless of the size of the Anεchlußöffnungen Schalldämpferε share the Dämpfungε- be introduced.
Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß das Gehäuεe aus zwei miteinander verbindbarer. Gehäusehalften besteht, in denen nebeneinander liegend je¬ weils ein erster und zweiter halbkreisförmiger Kanal ausge- formt ist, m welche Kanäle die Dämpfungsteile vor dem Zusam¬ menfügen der Gehäusehälften einsetzbar εind. Damit können die Dämpfungsteile unabhängig von der jeweiligen Form und Größe der Anschlußόffnungen des Schalldämpfers in die Ein- und Aus¬ laßstrecke des Schalldämpfers eingebracht werden. Die zwei¬ teilige Ausbildung des Schalldämpfergehäuses bietet ferner die Möglichkeit, die Anschlußöffnungen des Schalldämpfers alε Anschlußstutzen auszubilden, da die mit der Ausbildung sol¬ cher Stutzen verbundenen Hinterschneidungen an dem Gehäuse bei zweiteiliger Ausführung auch im Gußverfahren ohne weite¬ res herstellbar sind.The object is achieved according to the invention in that the housing consists of two interconnectable. There are housing halves in which a first and a second semicircular channel are formed lying side by side, which channels the damping parts can be used before the housing halves are joined together. So that can Damping parts are introduced into the inlet and outlet sections of the muffler regardless of the shape and size of the connection openings of the muffler. The two-part design of the muffler housing also offers the possibility of designing the connection openings of the muffler as connecting pieces, since the undercuts on the housing associated with the formation of such pieces can also be produced in a two-part design using the casting process without further processing.
Dadurch, daß jede Gehäusehälfte um ihre zwischen dem ersten und zweiten Kanal liegende Mittenachse gegenüber ihrer Trenn¬ ebene konvex gewölbt iεt, wird ein dichtes Verbinden der Gehäusehälften begünstigt. Durch die konvexe Wölbung der Gehäusehälften wird ein die Dichtigkeit erhöhendes Anpressen der entsprechenden Gehäusekanten über die volle Breite der Gehäusehälften erreicht.The fact that each housing half is convexly curved about its central axis lying between the first and second channels with respect to its parting plane favors a tight connection of the housing halves. The convex curvature of the housing halves ensures that the corresponding housing edges are pressed tightly over the full width of the housing halves.
Eine weitere Verbesserung der Abdichtung der zusammengefügten Gehäusehälften läßt εich dadurch erreichen, daß an den in der Trennebene der Gehäuεehälften liegenden Kantenflächen der den erεten und zweiten Kanal begrenzenden Wandteile Nut- und Federteile ausgebildet sind, die beim Zusammenfügen der Gehäusehälften ineinander greifen.A further improvement in the sealing of the joined housing halves can be achieved in that tongue and groove parts are formed on the edge surfaces of the wall parts delimiting the first and second channels in the parting plane of the housing halves, which engage when the housing halves are joined together.
Eine identiεche Auεbildung der beiden Gehäuεehälften ist dann möglich, wenn bei jeder Gehäuεehälft§ an den den einen Kanal begrenzenden Wandteilen eine Nut und an den den anderen Kanal begrenzenden Wandteilen eine Feder auεgebildet iεt.An identical configuration of the two housing halves is possible if, for each housing half, a groove is formed on the wall parts delimiting the one channel and a tongue is formed on the wall parts delimiting the other channel.
Anhand eines in der Zeichnung dargestellten Auεführungε- beispieles wird die Erfindung nachfolgend näher beschrieben. Eε zeigt :The invention is described in more detail below on the basis of an exemplary embodiment shown in the drawing. Eε shows:
FIG 1 zwei zu einem Schalldämpfergehäuse zusammenfügbare Gehäuεehälften FIG 2 eine Draufsicht auf die in der Trennebene liegende Seite einer Gehäusehälfte.1 shows two housing halves which can be joined together to form a silencer housing 2 shows a plan view of the side of a housing half lying in the parting plane.
Mit 1 ist eine obere und mit 2 eine untere Gehäusehälfte eines Schalldämpfergehäuses bezeichnet. Beide Gehäusehälften 1 und 2 εind identisch ausgebildet, εo daß von der Fertigung her nur eine Ausführungsform für beide Hälften notwendig iεt. Jede Gehäuεehälfte weiεt einen erεten und zweiten halbkreis¬ förmigen Kanal 3 bzw. 4 auf. Nach dem Zusammenfügen der beiden Gehäuεehälften 1 und 2 entεteht auε den halbkreiε- förmigen Kanälen 3 und 4 jeweilε ein rohrförmiger Einεtröm- kanal 5 bzw. ein rohrförmiger Auεεtrömkanal 6. In die halb¬ kreisförmigen Kanäle 3 und 4 werden in der Zeichnung nicht dargestellte, rohrförmig gestaltete Dämpfungsteile einge- setzt, die nach dem Zusammenfügen der Gehäusehälften 1 und 2 in dem rohrformigen Einströmkanal 5 bzw. Ausströmkanal 6 durch Formschluß gehalten werden. Die Gehäusehälften 1 und 2 sind um die zwischen den halbkreisförmigen Kanälen liegende Längsmittenachεe gegenüber der Trennebene 7 der Gehäuεe- halften 1 und 2 konvex gewölbt. Dieεe Wölbung iεt in der Zeichnung nicht erkennbar.1 designates an upper and 2 a lower housing half of a silencer housing. Both housing halves 1 and 2 are of identical design, so that only one embodiment is necessary for both halves in terms of manufacture. Each half of the housing has a first and a second semicircular channel 3 or 4. After the two housing halves 1 and 2 have been joined together, the semicircular channels 3 and 4 each have a tubular inflow channel 5 or a tubular outflow channel 6. The semicircular channels 3 and 4 do not show any tubular in the drawing designed damping parts are used, which are held in the tubular inflow channel 5 or outflow channel 6 by positive locking after the housing halves 1 and 2 have been joined together. The housing halves 1 and 2 are curved convexly around the longitudinal center axis lying between the semicircular channels with respect to the parting plane 7 of the housing half 1 and 2. This curvature cannot be seen in the drawing.
An den in der Trennebene 7 liegenden Kantenflächen 8 der die halbkreisförmigen Kanäle 3 und 4 begrenzenden Wandteile 9 εind Nuten 10 und Federn 11 vorgesehen. Die Nuten 10 undGrooves 10 and tongues 11 are provided on the edge surfaces 8 of the wall parts 9 which delimit the semicircular channels 3 and 4 in the parting plane 7. The grooves 10 and
Federn 11 εind abmessungsmäßig einander angepaßt, so daß sie ineinander fügbar sind. Ferner sind bei jeder Gehäusehälfte 1 und 2 an den den einen halbkreisförmigen Kanal 4 begrenzenden Wandteilen 9 nur Federn 11 und an den den anderen halbkreiε- förmigen Kanal 3 begrenzenden Wandteilen 9 nur Nuten 10 vor¬ gesehen. An der Kantenfläche δ des zwiεchen den halbkreis¬ förmigen Kanälen 3 und 4 liegenden Mittenwandteiles 12 sind dementsprechend jeweils eine Nut 10 und eine Feder 11 auεge¬ bildet. Damit ergibt sich eine identische Ausführungsform für das obere und untere Gehäuseteil 1 und 2. Die beiden Gehäuεe- teile 1 und 2 können daher durch Umschlag deε einen Gehäuse- teils 1 bzw. 2 mit dem anderen Gehäuseteil 2 bzw. 1 zu einem vollständigen Schalldämpfergehäuse zusammengefügt werden.Springs 11 are dimensionally matched to one another so that they can be fitted into one another. Furthermore, only springs 11 are provided in each housing half 1 and 2 on the wall parts 9 delimiting a semicircular channel 4 and only grooves 10 are provided on the wall parts 9 delimiting the other semicircular channel 3. Accordingly, a groove 10 and a tongue 11 are respectively formed on the edge surface δ of the central wall part 12 lying between the semicircular channels 3 and 4. This results in an identical embodiment for the upper and lower housing parts 1 and 2. The two housing parts 1 and 2 can therefore be turned by partly 1 or 2 with the other housing part 2 or 1 are combined to form a complete silencer housing.
Durch die erwähnte konvexe Ausbildung der Gehäuseteile 1 und 2 gegenüber ihrer Trennebene 7 wird außerdem das Zusammen- fügen der Gehäuεeteile 1 und 2 erleichtert. Infolge der kon¬ vexen Wölbung greifen die Gehäuseteile 1 und 2 beim Zusammen¬ fügen zunächst mit der an dem Mittenwandteil 12 vorgesehenen Nut 10 Feder 11 ineinander. Nach dem Ineinanderschieben dieser Nut 10 und Feder 11 ergibt εich eine Zwangsführung, so daß beim weiteren Zusammendrücken der beiden Gehäusehälften 1 und 2 die Nuten 10 und Federn 11 in den übrigen Bereichen durch das durch die konvexe Wölbung bedingte Abrollen ohne weitereε ineinander gleiten.The aforementioned convex design of the housing parts 1 and 2 relative to their parting plane 7 also makes it easier to join the housing parts 1 and 2 together. As a result of the convex curvature, the housing parts 1 and 2 initially engage in the groove 10 provided on the central wall part 12 when the parts are joined together. After this groove 10 and tongue 11 have been pushed into one another, there is a positive guide, so that when the two housing halves 1 and 2 are further compressed, the grooves 10 and tongues 11 slide into one another in the remaining areas due to the rolling caused by the convex curvature without further movement.
Die beiden Gehäuεehälften 1 und 2 werden nach dem Zusammen¬ fügen in geeigneter Weise, beispielεweise mittels Schrauben, Nieten oder auch durch Verschweißen der in der Trennebene 7 liegenden Furche, miteinander verbunden. After the joining, the two housing halves 1 and 2 are connected to one another in a suitable manner, for example by means of screws, rivets or also by welding the groove lying in the parting plane 7.
