Description

  

  Einrichtung zum Rückführen von Öl aus dem Verdampfer in den Kompressor von       Kältemaschinen.       Die Erfindung betrifft eine Einrichtung  zum Rückführen von Öl aus dem Verdamp  fer in den Kompressor von Kältemaschinen  nach dem Patentanspruch des Hauptpatentes  und besteht darin, dass der unter niedrige  rem Druck als der Verdampfer gehaltene  Raum, an den die     Ölrückleitung    des     Ölsamm-          lers    angeschlossen ist, als Saugraum eines       Injektors    ausgebildet ist, der von dem dem  Kompressor zuströmenden Kältemittel be  trieben wird.

   Dadurch wird der Fortschritt  erzielt, dass das Rückführen des Öls in den  Kompressor mit kleinerem     Kraftverlust    als  bisher und ohne die     Verdampfungstempera-          tur    ungünstig zu beeinflussen, selbsttätig be  werkstelligt wird.  



  Ein Ausführungsbeispiel des Erfindungs  gegenstandes ist auf der Zeichnung darge  stellt.  



  Der Kompressor ist, wie im Haupt  patent, mit 1, der Verdampfer mit 4, die       Kältemittelzuleitung    zum Kompressor mit 8,  der Ölsammler des Verdampfers mit 26 und    die     Ölrückleitung    desselben mit 2 7 bezeich  net. Nach der Erfindung ist der durch die  Saugwirkung des     Kompressors    unter niedri  gerem Druck als der Verdampfer gehaltene  Raum, in den die     Ölrückleitung    einmündet,  anstatt, wie bisher, im Kompressor selbst  angeordnet zu sein, als Saugraum 36 eines       Injektors    37 ausgebildet, der so in die Saug  leitung 8 des Kompressors eingeschaltet ist,

    dass er vom     Kältemittel    betrieben     wird.    Das  im Raum 26 sich sammelnde Öl     wird    auf  diese Weise mit sehr kleinem Druckverlust  des angesaugten Kältemittels in den Saug  raum 36 hochgehoben, von dem aus es, wenn  derselbe annähernd voll ist, von dem mit  grosser Geschwindigkeit durchströmenden       Kältemittel    mitgerissen und in zerstäubtem  Zustande in den Kompressor zurückgeführt       wird.  



  Device for returning oil from the evaporator to the compressor of refrigerating machines. The invention relates to a device for returning oil from the evaporator fer into the compressor of refrigerating machines according to the claim of the main patent and consists in the fact that the space kept under lower rem pressure than the evaporator to which the oil return line of the oil collector is connected, is designed as a suction chamber of an injector which is operated by the refrigerant flowing into the compressor.

   This achieves the progress that the oil is returned to the compressor with less power loss than before and without having an unfavorable effect on the evaporation temperature.



  An embodiment of the subject invention is on the drawing provides Darge.



  As in the main patent, the compressor is denoted by 1, the evaporator by 4, the refrigerant supply line to the compressor by 8, the oil collector of the evaporator by 26 and the oil return line by 2 7. According to the invention, the space held by the suction of the compressor under niedri gerem pressure than the evaporator, into which the oil return line opens, instead of being arranged in the compressor itself as before, is designed as a suction chamber 36 of an injector 37, which is so in the Suction line 8 of the compressor is switched on,

    that it is operated by the refrigerant. The oil that collects in space 26 is lifted in this way with a very small pressure loss of the sucked refrigerant into the suction space 36, from which, when it is almost full, it is carried away by the refrigerant flowing through at high speed and in an atomized state in the Compressor is returned.
