摘要： The invention relates to a suction device (1), preferably for a tunnel (2), especially for a tunnel for vehicles, comprising at least one vortex hood, (4, 5). In order to improve the suction properties of said suction device (1), to prevent it from being damaged, to a large extent, in the event of a fire, and to be able to act directly on the source of fire, at least one injection device (17) comprising at least one nozzle (18) is provided, said nozzle (18) being arranged on or in the vortex hood (4, 5) and being embodied in such a way that it produces a spray mist consisting of fine droplets (32).

摘要： The invention relates to a suction device (1) for a tunnel (2), especially a tunnel for vehicles, comprising at least one channel (3) having an upper limit and a lower limit, and two vortex hoods (4, 5). The aim of the invention is to provide a suction device which is easy and cheap to produce and which can be just as easily and quickly integrated into new structures as into existing tunnel installations. To this end, the vortex hoods (4, 5) are arranged between the upper limit and the lower limit and the channel (3) is laterally defined by each vortex hood (4, 5).
