1. Vorrichtung zur Rückführung der aus der Saugleitung einer Kältemaschine abgeschiedenen Kälteflüssigkeit, dadurch gekennzeichnet, daß in die Saugleitung zwischen Verdichter und Verdampfer ein Flüssigkeitsabscheider F eingeschaltet ist, aus dem die abgeschiedene Flüssigkeit durch eine Rohrleitung in die Flüssigkeitsleitung vor oder hinter dem Regelungsventil R¹ zwischen Condensator und Verdampfer entweder mit Hülfe einer Pumpe P oder eines Injectors K oder mit Hülfe des Ueberdruckes der Flüssigkeit im Abscheider F zurückgeführt wird.1. Device for returning the refrigerant liquid separated from the suction line of a refrigeration machine, characterized in that a liquid separator F is switched on in the suction line between the compressor and the evaporator, from which the separated liquid through a pipe into the liquid line before or after the control valve R ¹ between Condenser and evaporator either with the aid of a pump P or an injector K or with the aid of the excess pressure of the liquid in the separator F is returned.

PATENT OFFICE.

In cold steam engines with several steamers connected in parallel and specifically in cooling systems with the arrangement of the evaporator as an immediate air cooler, the Circumstances annoying and often dangerous to the fact that the refrigerant is in too large quantities get into the evaporator and the remainder that is not evaporated in the Compressor cylinder torn over, liquid hammer caused.

The present arrangement has been made to prevent these evils. It essentially consists of a liquid separator F, connected to the suction line S between the evaporators and the compressor, further in connection with F of a device for returning the separated liquid to the liquid line and finally of a connecting pipe M with control valve J? ² between F and the compressor C. Separator F is easiest to be set higher than C so that the separated liquid can flow through R ² and M to the compressor by itself.

The device for returning the cold liquid into the liquid line can be a small pump P or a steam or liquid jet apparatus K.

The introduction of the liquid into the liquid line can take place, depending on the type of return device, on the condenser or evaporator side of the control valve R ¹ that has been customary since then. In the case of a liquid jet device, it can be conveniently connected to the control valve.

In special cases, if z. B. the air cooler are much lower than the cooling machine, is the return of the separated liquid without a pump or jet device through a connecting tube between Separator and. Liquid line (suction side) only as a result of the overpressure the liquid column possible.

So that the compressor is not damaged by sucking in dry vapors and the associated overheating, a part of the separated liquid to be regulated by R ' ^{2 is} fed through M to the compressor on the suction side. In order to ensure that liquid remains, especially for the latter purpose, the piercing ρ is arranged higher than the piercing m.
