Schleudergebläse, insbesondere zum
Aufladen von BrennkraftmaschinenCentrifugal fan, especially for
Charging of internal combustion engines

Die Erfindung bezieht sich auf ein Schleudergebläse, insbesondere zum Aufladen von Brennkraftmaschinen, mit einem in bezug auf den radialen Luftaustritt aus des Verdichterlaufrad seitlich versetzten Spiralgehäuse zur Erzeugung einer Drallströmung.The invention relates to a centrifugal fan, in particular for charging internal combustion engines, with an in with respect to the radial air outlet from the compressor impeller laterally offset spiral housing to generate a Swirl flow.

Es sind Saugzugaxialgebläse mit einer vor dem Laufrad angeordneten, drallerzeugenden Leitvorrichtung bekannt, um die in der Luft befindlichen Verunreinigungen, wie Staub und Büß, auszuschleudern, wobei der mit den Verunreinigungen angereicherte, äußere Luftmantel vor dem Gebläselaufrad über am Umfang des Strömungskanales liegende öffnungen abgeführt wird, während der staubfreie Luftkern vom G-ebläselaufrad erfaßt und weitergefördert wird.There are induced draft axial fans with a Swirl-generating guide device known to the airborne contaminants, such as dust and Penance to be thrown out, whereby the enriched with the impurities, outer air jacket in front of the fan impeller Openings located on the circumference of the flow channel are removed is captured while the dust-free air core is captured by the G-fan impeller and is further funded.

Me Erfindung hat sich die Aufgabe gestellt, die an sich bekannte Maßnahme einer Aufteilung der vom Gebläse angesaugten, gesamten Luft in einen staubfreien Luftkern und einen mit Staub angereicherten Luftmantel auch bei einem Schleudergebläse mit einem axialen Lufteintritt und einem radialen Luftauetritt aus dem Verdichterlaufrad mit einfachen Mitteln su verwirklichen·Me invention has set itself the task of the known measure of a division of the sucked in by the fan, all air into a dust-free air core and an air jacket enriched with dust, even with a centrifugal fan with an axial air inlet and a radial air outlet from the compressor impeller with simple means to realize

Um dies zu erreichen? wird erfindungsgemäß vorgeschlagen, am Ende des Spiralgehäuses eine gegenüber dem Spiralgehäuseende mit kleinerem Durehmesser versehene Leitung anzuschliessen, deren vorderes Ende sur Bildung einer Luftfangtasche in Strömungsrichtung des Gases bzw. der Luft gesehen vor dem hinteren Ende des Spiralgehäuses liegt t wobei am Außenumfang des Spiralgehäuseendes eine oder mehrere Öffnungen zum Ausscheiden des mit Staub bzw. Verunreinigungen angereicherten Gas- bzw. Luftmantels angeordnet sind.To achieve this? the invention proposes to connect a with respect to the volute casing end provided with a smaller Durehmesser line at the end of the spiral housing, seen whose front end sur form an air-collecting pocket in the direction of flow of the gas or the air in front of the rear end of the spiral housing is t wherein on the outer circumference of the spiral housing end one or a plurality of openings for discharging the gas or air jacket enriched with dust or impurities are arranged.

Um günstige Strömungsverhältnisse im fraglichen Bereich zu schaffen und eine gesteigerte Auszentrifugierung der Verunreinigungen zu erlangen, wird in Ausgestaltung der Erfindung weiter vorgeschlagen, das Spiralgehäuseende mit einem trichterförmigen !Fortsatz zu versehen.In order to achieve favorable flow conditions in the area in question create and achieve an increased centrifugation of the impurities, is in an embodiment of the invention further proposed to provide the volute casing end with a funnel-shaped extension.
