KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die nachfolgend beschriebene und durch Zeichnungen erläuterte Vorrichtung bezweckt an Exhaustoren mit Compressionswirkung durch je nach Bedürfnifs genau einzustellende Rückoder Vor-Ueberströmung das geförderte Gasquaritum auf die Druckhöhe im Druckrohr zu bringen, bevor die Eröffnung nach dem Druckrohr hin erfolgt ist. Es sollen die bei Nichtvorhandensein einer solchen Vorrichtung auftretenden Stöfse und damit verbundenen plötzlich erhöhten Arbeitswiderstände und Druckverluste vermieden werden.The device described below and illustrated by drawings aims at Exhaustors with compression effect thanks to the back or rear that can be set precisely as required Pre-overflow the pumped gas quarity towards the pressure level in the pressure pipe before the opening to the pressure pipe has taken place. There should be those in the absence of them shock occurring with such a device and the associated suddenly increased work resistance and pressure losses be avoided.
Mehrere gekreuzte Kanäle Ar und Ar1, deren Anzahl je nach Gröfse des Exhaustors wechselt, sind vom Druckstutzen aus nach dem Gehäuseinnern . vorgesehen; die schräg liegenden Kanäle Ar1 haben bei jeder dieser Kanalcombinationen eine andere Neigung zur horizontalen Mittellinie H-M, so dafs jeder Kanal Ar1 in anderer Höhenlage in das Gehäuse einmündet als jeder der vorhergehenden und folgenden. Wenn der Flügel /2 die Saugseite abgeschlossen hat, so hat der Flügel J1 noch einen bestimmten Weg zurückzulegen, bevor die Verbindung nach der Druckseite eröffnet wird. Bei dieser Vorwärtsbewegung in der Drehrichtung, während welcher Zeit zugleich Compression stattfindet, schreitet der Flügel J1 nach und nach über die in verschiedener Höhenlage liegenden Einmündungsöffnungen der Kanäle Ar1 weg. Derart eröffnen die Kanäle Ar bis Ar1 allmälig auf einander folgend die Communication zwischen Förderzelle und Druckrohr. Die Ventilschrauben u gestatten, infolge der Kegelspitzen die Durchgangsöffnung vom Kanal Ar zu Ar1 beliebig zu verengen - oder ganz abzuschliefsen, so dafs die Üeberströmung nach Zeitpunkt und Menge genau eingestellt werden kann. In der zweiten Figur ist die Stellung einer theilweisen Ueberrstömung gezeigt. Die ersten tiefer liegenden Kanäle sind ganz geöffnet, die mittleren theilweise, die letzteren ganz geschlossen.Several crossed channels Ar and Ar 1 , the number of which changes depending on the size of the exhaustor, are from the pressure port to the inside of the housing. intended; the inclined channels Ar 1 in each of these channel combinations have a different inclination to the horizontal center line HM, so that each channel Ar 1 opens into the housing at a different height than each of the preceding and following. When wing / 2 has closed the suction side, wing J 1 still has to cover a certain distance before the connection to the pressure side is opened. During this forward movement in the direction of rotation, during which time compression takes place at the same time, the wing J 1 gradually moves away over the confluence openings of the channels Ar 1 which are at different altitudes. In this way, the channels Ar to Ar 1 gradually open the communication between the delivery cell and the pressure pipe, one after the other. The valve screws u allow the passage opening from the channel Ar to Ar 1 to be narrowed at will due to the cone tips - or to close it off completely, so that the overflow can be precisely adjusted according to time and amount. In the second figure the position of a partial overflow is shown. The first deeper canals are completely open, the middle partially, the latter completely closed.
Nach Herausnahme der Schrauben u und n> sind die Kanäle sofort zu reinigen.After removing the screws u and n> , the ducts must be cleaned immediately.
Die für dreiflügelige Exhaustoren gezeichnete Vorrichtung ist auch für solche von jeder anderen Flügelzahl verwendbar.The device drawn for three-winged exhaustors is also suitable for those of everyone other number of wings can be used.
