Abstract

The invention relates to a spraying device (1) that is used to spray machine parts (5) or at-risk areas in mining, tunnel construction, and civil engineering. The spraying device has a plurality of nozzles (2, 3, 4), from each of which a spray cone (6, 7, 8) of a water-air mixture directed at the at-risk machine part (5) or the at-risk area is discharged. The nozzle (2, 3, 4) has an elongated housing (9) having a central channel (11), the rear end (12) of which is used to connect to a water supply and the front end (13) of which is used to discharge the water-air mixture. The housing (9) has a plurality of holes (14, 15, 16) for supplying air, which are positioned evenly over the circumference of the nozzle (2, 3, 4) and which open laterally into the channel (11).
