Description
Die Erfindung betrifft einen Schwimmerhahn, insbesondere für Kältemaschinen. Sie besteht darin, daß der Hahn von" zwei ineinander angeordneten Küken gebildet wird, die von dem Schwimmer in entgegengesetztem Sinne gedreht werden. Damit wird bei nur kleinen Schwankungen des Kälteflüssigkeitsspiegels und bei gedrängter Bauart eine 'starke Veränderlichkeit des von den Küken freigegebenen Querschnitts der Drosselöffhung erzielt.The invention relates to a float tap, in particular for refrigerating machines. she consists in the fact that the cock is formed by "two nested chicks which be turned in the opposite direction by the float. This means that there are only small fluctuations in the refrigerant liquid level and in the case of a compact design, there is considerable variability in what is released by the chicks Cross section of the throttle opening achieved.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung zur Veranschaulichung gebracht.An exemplary embodiment of the subject matter of the invention is shown on the drawing for illustration brought.
α ist ein durch die Leitung b mit dem Kondensator und durch die Öffnung c mit dem Verdampfer einer Kältemaschine verbundener Sammelbehälter, aus dem die vom Kondensator gelieferte Kälteflüssigkeit mit ao Hilfe einer vom Schwimmer d zu beeinflussenden verstellbaren Drosselvorrichtung jeweils in solcher Menge an den Verdampfer überzuführen ist, daß der im Behälter sich einstellende Flüssigkeitsspiegel sich nur innerhalb gegebener Grenzen bewegt. Die Drosselvorrichtung besteht bus zwei rohrförmigen! Drehschiebern e und /, die mit nach unten gerichteten, in die Leitung zum Verdampfer mündenden Schlitzen g versehen und mittels je eines Gestänges h, i mit dem Schwimmer verbunden sind. Diese Schieber werden von dem mit dem Flüssigkeitsstand im Behälter seine Lage ändernden Schwimmer so gegeneinander verdreht, daß der von den Schlitzen freigegebene Durchflußquerschnitt mit steigendem Flüssigkeitsstand eine Vergrößerung und mit sinkendem. Flüssigkeitsstand eine Verkleinerung erfährt. Um dem Schwimmer eine stets zentrale Lage zu sichern, sind die Hebel h durch Lenker k zu einem Gelenkparallelogramm verbunden, dessen den Schiebern gegenüberliegender Gelenkpunkt in einer vertikalen Führung I gleitet. Mit den Schiebern e und / sind noch Gegengewichte m verbunden, die den Zweck haben, die Verstellkraft der Schieber bei sinkendem Flüssigkeitsstand zu erhöhen. Die so ausgebildete Drosselvorrichtung kann natürlich auch für andere Zwecke als für Kältemaschinen Verwendung finden. α is a collecting tank connected through line b to the condenser and through opening c to the evaporator of a refrigeration machine, from which the refrigerant liquid supplied by the condenser is to be transferred to the evaporator in such an amount with the aid of an adjustable throttle device that can be influenced by the float d that the liquid level in the container moves only within given limits. The throttle device is made up of two tubular bus! Rotary valves e and /, which are provided with downwardly directed slots g opening into the line to the evaporator and each connected to the float by means of a linkage h, i. These slides are rotated against each other by the float, which changes its position with the liquid level in the container, so that the flow cross-section released by the slots increases with increasing liquid level and with decreasing. The liquid level experiences a decrease. In order to ensure that the swimmer is always in a central position, the levers h are connected by means of links k to form an articulated parallelogram, the articulation point of which, opposite the slides, slides in a vertical guide I. Counterweights m are also connected to the slides e and /, which have the purpose of increasing the adjusting force of the slides when the liquid level drops. The throttle device designed in this way can of course also be used for purposes other than refrigeration machines.
