<p>A device (100) and a method for ejecting a fluid (L) are provided. The device comprises a main pipe (60), a rotatable housing (107) connected to the main pipe (60) and a hub (110) provided with a nozzle (112). The hub (110) is rotatably connected to the housing (107). The fluid is arranged to be conveyed through the main pipe and the housing (107) to said nozzle (112) for ejection of the fluid, and the hub (110) is arranged to rotate about an axis (A3) arranged with an angle ± in relation to a longitudinal axis (A1) of the main pipe (60). The device (100) is characterized in that the angle ± between the axes (A1 and A3) is arranged to vary between 90-² and 90+², ² ‰¥ 0, when the housing (107) rotates one revolution.</p> |
