Fluid flow actuated tool

1. A fluid flow actuated tool, comprising:

a housing comprising a housing interior, said housing interior receiving a flow of fluid;

a tool; and

an actuating mechanism comprising a fluid wheel structure, said fluid wheel structure being connected to said tool, at least a portion of said fluid wheel structure being arranged in said flow of fluid for rotating said fluid wheel structure, wherein said tool is actuated based on rotation of said fluid wheel structure, said fluid wheel structure comprising a plurality of fluid engaging structures, each of said fluid engaging structures comprising fluid engaging material, said fluid engaging material comprising a plurality of raised fluid engaging portions for engaging said flow of fluid, said fluid wheel structure comprising a plurality of radially extending portions, each of said radially extending portions comprising an end portion, said end portion comprising one of said fluid engaging structures.

2. A fluid flow actuated tool in accordance with claim 1 , wherein said one of said fluid engaging structures defines a surface comprising a plurality of elevated areas.

3. A fluid flow actuated tool in accordance with claim 2 , wherein said surface comprises a plurality of non-elevated areas, each of said non-elevated areas being defined between one of said elevated areas and another one of said elevated areas.

4. A fluid flow actuated tool in accordance with claim 1 , wherein each of said fluid engaging structures comprises a first portion and a second portion extending in a radial direction with respect to a longitudinal axis of said fluid wheel structure, each of said fluid engaging structures further comprising a third portion and a fourth portion extending in an axial direction with respect to said longitudinal axis of said fluid wheel structure, said first portion being parallel to said second portion, said third portion being parallel to said fourth portion, each of said plurality of raised fluid engaging structures being arranged between said first portion, said second portion, said third portion and said fourth portion.

5. A fluid flow actuated tool in accordance with claim 1 , wherein said tool comprises a tool shaft, said housing comprising a tool shaft receiving opening, at least a portion of said tool shaft being arranged in said tool shaft receiving opening.

6. A fluid flow actuated tool in accordance with claim 5 , wherein said housing comprises a housing fluid guide member having an opening located adjacent to said tool shaft, wherein said housing fluid guide member conveys fluid from said interior of said housing to an environment external to said housing via said opening.

7. A fluid flow actuated tool in accordance with claim 6 , wherein said housing comprises a nozzle, wherein fluid exits said housing via said nozzle.

8. A fluid flow actuated tool in accordance with claim 6 , wherein said housing comprises another opening located at a radially spaced location from said tool shaft, wherein said fluid flows from said interior of said housing to said environment external to said housing via said opening.

9. A fluid flow actuated tool in accordance with claim 8 , wherein said housing comprises a housing connector for connecting said housing to a fluid supply line for supplying said flow of fluid to said interior of said housing.

10. A fluid flow actuated tool in accordance with claim 1 , wherein said housing is connected to a fluid delivery device, wherein said housing forms an outlet of said fluid delivery device.

11. A fluid flow actuated tool in accordance with claim 10 , wherein said housing forms a portion of said fluid delivery device.

12. A fluid flow actuated tool in accordance with claim 10 , wherein said housing comprises a housing cover, said housing cover being pivotably connected to said fluid delivery device.

13. A fluid flow actuated tool in accordance with claim 1 , further comprising:

a fluid guide member for guiding at least a portion of said flow of fluid, said fluid guide member comprising an inner fluid guiding surface having a radial slope, said radial slope increasing in a radial direction from a first side of said fluid guide member to a second side of said fluid guide member with respect to a longitudinal axis of said fluid guide member.

14. A fluid flow actuated tool in accordance with claim 13 , wherein said inner fluid guiding surface comprises an axial slope, said axial slope increasing in an axial direction from a third side of said fluid guide member to a fourth side of said fluid guide member.

15. A fluid flow actuated tool in accordance with claim 13 , further comprising:

a nozzle connected to said housing, said fluid guide member being arranged in said interior of said housing and said fluid member being configured to guide said portion of said flow of fluid in a direction of said nozzle.
