Abstract

Ein Absaugvorrichtung (2) weist ein Gehäuse (4), an dem ein Sauganschluss (8) und ein Luftauslass (12) vorgesehen sind und eine in dem Gehäuse (4) aufgenommene Gebläseanordnung (6) zur Erzeugung eines Luftstromes (L) vom Sauganschluss (8) zum Luftauslass (12) auf, die ein erstes Gebläse (18) und ein zweites Gebläse (20) umfasst. Dabei ist vorgesehen, dass das erste Gebläse (18) über eine Strömungskammer strömungsmäßig mit dem zweiten Gebläse (20) verbunden ist, die durch eine Aufnahmekammer (24) gebildet ist, in der das erste Gebläse (18) und das zweite Gebläse (20) gemeinsamen angeordnet sind und die eine Einlassöffnung (26), an der ein Ansaugkanal (30) des ersten Gebläses (18) angeschlossen ist und eine Auslassöffnung (28), an der ein Abblaskanal (32) des zweiten Gebläses (20) angeschlossen ist, aufweist.

Figure imgaf001
A suction device (2) has a housing (4) on which a suction connection (8) and an air outlet (12) are provided and a blower arrangement (6) accommodated in the housing (4) for generating an air flow (L) from the suction connection (12). 8) to the air outlet (12), which comprises a first blower (18) and a second blower (20). It is provided that the first fan (18) via a flow chamber in fluid communication with the second fan (20) is formed by a receiving chamber (24), in which the first fan (18) and the second fan (20). are arranged together and an inlet opening (26) to which an intake passage (30) of the first blower (18) is connected and an outlet opening (28) to which a Abblaskanal (32) of the second blower (20) is connected ,
