Abstract

A device and a method for ejecting a fluid are provided. The device comprises a main pipe, a rotatable housing connected to the main pipe and a hub provided with a nozzle. The hub is rotatably connected to the housing. The fluid is arranged to be conveyed through the main pipe and the housing to said nozzle for ejection of the fluid, and the hub is arranged to rotate about an axis arranged with an angle α in relation to a longitudinal axis of the main pipe. The angle α between the axes is arranged to vary between 90−β and 90+β, 2≦β≦45, when the housing rotates one revolution.

Claims

1. A device for ejecting a fluid comprising a main pipe, a rotatable housing connected to the main pipe and a hub provided with a nozzle, said hub being rotatably connected to the housing, said fluid being arranged to be conveyed through the main pipe and the housing to said nozzle for ejection of the fluid, and the hub being arranged to rotate about an axis arranged with an angle α

in relation to a longitudinal axis of the main pipe, the device comprising a connection part arranged between the main pipe and the housing, wherein the connection part comprises a bent pipe, a first end of which is connected to the main pipe and a second end of which is connected to the housing, wherein the angle α

between the axes is arranged to vary between 90−

β and

90+β

, 2≦

β

≦

45, when the housing rotates one revolution, such that the main pipe is hit by the fluid from the nozzle at a varying height.

2. A device according to claim 1, wherein the housing is rotatably connected to the main pipe.

3. A device according to claim 1, wherein a direction of fluid ejection from the nozzle is essentially perpendicular to the axis about which the hub is arranged to rotate.

4. A device according to claim 1, wherein the housing is arranged to rotate about an axis arranged with an angle γ

≠

0 in relation to the longitudinal axis of the main pipe.

7. A device according to claim 1, wherein a rotational speed of the housing differs from a rotational speed of the hub.

5. (canceled)

6. (canceled)

9. A method according to claim 6, comprising ejecting the fluid through the nozzle in a direction essentially perpendicular to the axis about which the hub is rotated.

10. A method according to claim 6, comprising rotating the housing in relation to the main pipe about an axis.

14. A method according to claim 6, comprising rotating the housing and the hub with different rotational speeds.

8. A method for ejecting a fluid comprising

providing a main pipe, a rotatable housing connected to the main pipe and a hub provided with a nozzle, said hub being rotatably connected to the housing,

conveying the fluid through said main pipe, further through the housing and to said nozzle,

ejecting the fluid trough the nozzle,

rotating the hub about an axis arranged with an angle α

in relation to a longitudinal axis of the main pipe,

providing a connection part between the main pipe and the housing, the connection part including a bent pipe between the main pipe and the housing, a first end of the bent pipe being connected to the main pipe and a second end of the bent pipe being connected to the housing, and

varying the angle α

between the axes between 90−

β and

90+β

, 2≦

β

≦

45, when the housing rotates one revolution, such that the main pipe is hit by the fluid from the nozzle at a varying height.

11. A method according to claim 8, comprising providing the axis with an angle γ

≠

0 in relation to the longitudinal axis of the main pipe.
