Description

  

      Selialldämpfer    an     Kolbenmaschinen.       Es ist bekannt, auf der Druckseite von       Kompressoren    und Pumpen sogenannte Schall  dämpfer einzubauen, um das Geräusch aus  dem Maschineninnern nach aussen zu dämpfen.  



  Gemäss vorliegender Erfindung wird der  Schalldämpfer auf der Saugseite eingebaut,  weil es sich gezeigt hat, dass auch auf der  Saugseite bei Kolbenmaschinen das Geräusch  vom Maschineninnern nach aussen gelangen  kann. Im Gegensatz zu den bekannten Aus  führungen können die Schalldämpfer auch  unmittelbar in das Maschinengehäuse oder  in den     LagQrschild    eingebaut sein.  



  Die beiliegende Zeichnung zeigt Aus  führungsbeispiele des     Erfindungsgegenstandes.          Fig.    1 zeigt im Schnitt einen Teil eines       Kolbenkompressors,    bei welchem die Luft  durch eine     ringsegmentförcnige        Öffnung    b       (Fig.    2) des Lagerschildes     ca    in den Saug  raum c gelangt. In der Öffnung b sitzt ein  Schalldämpfer d. Das angesaugte Medium  tritt bei g     (Fig.    3) in den Schalldämpfer und  umströmt mit mehreren Richtungswechseln  Leitbleche f, um bei e in den     Saugraum    c  der Maschine zu gelangen.

      Die     Fig.    4 und 5 zeigen je in Stirnan  sicht und in einem Horizontalschnitt weitere       Ausführungsformen    des Schalldämpfers. In       Fig.    4 sind zylindrische Bleche f einseitig  abgeschnitten, um freien     Durchgang    zu  schaffen. In     Fig.    5 besitzen die Leitbleche     f'     abwechselnd kleineren und grösseren Durch  messer; die Bleche von grösserem Durch  messer sind in der Mitte ausgeschnitten.  



  Der Schalldämpfer kann gleichzeitig als  Filter ausgebildet werden, indem derselbe  mit Filtermasse, wie     Rosshaar    usw. ausge  füllt wird.



      Selial damper on piston engines. It is known to install so-called sound absorbers on the pressure side of compressors and pumps in order to dampen the noise from the inside of the machine to the outside.



  According to the present invention, the silencer is installed on the suction side because it has been shown that the noise from the inside of the machine can also reach the outside on the suction side in piston engines. In contrast to the known designs, the silencers can also be installed directly in the machine housing or in the bearing plate.



  The accompanying drawing shows exemplary embodiments of the subject matter of the invention. Fig. 1 shows in section a part of a reciprocating compressor in which the air passes through a ring segmentförcnige opening b (Fig. 2) of the end shield approx into the suction space c. A silencer d is located in the opening b. The sucked in medium enters the silencer at g (Fig. 3) and flows around guide plates f with several changes of direction in order to get into the suction chamber c of the machine at e.

      4 and 5 each show in front view and in a horizontal section further embodiments of the muffler. In Fig. 4 cylindrical sheets f are cut off on one side in order to create free passage. In Fig. 5 have the baffles f 'alternately smaller and larger diameter; the larger-diameter sheets are cut out in the middle.



  The muffler can also be designed as a filter by the same with filter material, such as horsehair, etc. is filled out.
