  Umführungsleitung an einfach wirkenden Salmiakpumpen von Absorptionsmaschinen. 



   Die Erfindung betrifft einfach wirkende Salmiakpumpen von Absorptionsmaschinen mit   liogendor. Zylindor   und bezweckt, Ammoniskverluste, die der Stopfbüchse zuzuschreiben sind, sowie das Übertreten von Schmieröl in die Maschine zu vorhindern. Dies wird dadurch erreicht, dass in der   Umfuhrungsleitung,   die den Raum zwischen dem Kompressorkolben und seiner   Stopfbüchse   mit dem Saugraum der Pumpe verbindet, ein   Rückschlag-   ventil sowie ein Ölabscheider angeordnet sind. Die Zeichnung stellt ein Ausführungsbeispiel einer solchen Anordnung in einem Längsschnitt dar.

   Das   Umführungsrohr   a ist gegen den Saugraum b der Pumpe so durch ein Rückschlagventil c abgesperrt, dass wohl Flüssigkeit (infolge Undichtheit des Kolbens) aus dem Umführungsrohr in den Saugraum treten kann, aber nicht umgekehrt.   Ferner zist   in das Rohr a ein als Ölabscheider dienender Wind-

Hier sammelt sich das Öl auch dann an, wenn der   Ölabscheider   infolge Undichthoit des Kompressorkolbens sich mit Ammoniak füllt, da das Öl spezifisch schwerer als Ammoniak ist.

  Bypass line on single-acting ammonia pumps of absorption machines.



   The invention relates to single-acting salmiac pumps of absorption machines with liogendor. The purpose of the cylinder and cylinder is to prevent the loss of ammonia that can be ascribed to the stuffing box and the leakage of lubricating oil into the machine. This is achieved in that a non-return valve and an oil separator are arranged in the bypass line which connects the space between the compressor piston and its stuffing box with the suction chamber of the pump. The drawing shows an embodiment of such an arrangement in a longitudinal section.

   The bypass pipe a is blocked from the suction chamber b of the pump by a check valve c so that liquid (due to the piston leaking) can enter the suction chamber from the bypass pipe, but not vice versa. Furthermore, in the pipe a, serving as an oil separator, is
 EMI1.1
 Ö) stripped between the compressor piston and its stuffing box into the oil separator d, from the lower part of which it can be drained. The oil collects here even if the oil separator fills with ammonia due to a leak in the compressor piston, since the oil is specifically heavier than ammonia.
