Abstract
Vorrichtung (20) zur Kühlung eines Abgasstroms (18), mit einer mittels des Abgasstroms (18) beaufschlagbaren Auslassdüse (24), die derart in ein offenes Ende (26) eines angrenzenden Abgasrohrs (28) hineinragt, dass in einem zwischen der Auslassdüse (24) und dem Abgasrohr (28) gebildeten Ansaugbereich (30) bei Hindurchtreten des Abgasstroms (18) ein Unterdruck gegenüber der Umgebung (32) erzeugbar ist, dadurch gekennzeichnet, dass ein Stellmittel (44) zur Veränderung des Strömungsquerschnitts der Auslassdüse (24) vorgesehen ist. Device (20) for cooling an exhaust gas flow (18), with an exhaust nozzle (24) which can be acted upon by the exhaust gas flow (18) and protrudes into an open end (26) of an adjacent exhaust pipe (28) in one between the exhaust nozzle (18). 24) and the exhaust pipe (28) formed suction region (30) upon passage of the exhaust stream (18), a negative pressure relative to the environment (32) can be generated, characterized in that an adjusting means (44) for changing the flow cross-section of the outlet nozzle (24) is provided is.
