2. Tool (1) for a hydro cleaner machine according to claim 1, characterised in that said distribution device (8) comprises an external envelope (82) that defines a downflow conduit (80) adapted to connect the container tank (7) with the exterior, and a closure system (85, 86, 87) of said downflow conduit (80) adapted to be activated to permit or prevent the exit of the detergent.

3. Tool (1) for a hydro cleaner machine according to claim 2, characterised in that said distribution device (8) is associated with the conveyor conduit (5) for the high pressure water, in a manner so that the closure system (85, 86, 87) is activated by the pressure itself of the water.

4. Tool (1) for a hydro cleaner machine according to claim 2, characterised in that said closure system comprises a sliding valve (85) and elastic means (86) adapted to counter the movement of said valve (85);

said valve (85) being equipped with a rod (85b) and an obturator (85a) which, positioned inside the downflow conduit (80) is adapted to permit or prevent the exit of the detergent.

5. Tool (1) for a hydro cleaner machine according to claim 4, characterised in that said elastic counter means comprise a spring (86).

6. Tool (1) for a hydro cleaner machine according to claim 4, characterised in that the rod (85b) of said valve (85) presents at least one end section (85c) that extends inside the conveyor conduit (5).

7. Tool (1) for a hydro cleaner machine according to claim 4, characterised in that said closure system comprises a valve body (87) inside which is defined a guide seat (88) for the rod (85b) of the valve (85).

8. Tool (1) for a hydro cleaner machine according to claim 7, characterised in that said valve body (87) is fixed to the conveyor conduit (5) by connecting means (43, 87c) in turn associated with said valve bodies (87) and with the conveyor conduit (5).

9. Tool (1) for a hydro cleaner machine according to claim 8, characterised in that said connecting means comprise an attachment seat (43) obtained in a wall of the conveyor conduit (5) and adapted to connect the conveyor conduit (5) itself with the exterior;

and an insertion section (87c) of the valve body (87), adapted to couple with said seat (43) so that at least one end section (85c) of the rod (85b) of the valve (85) extends inside said conveyor conduit (5).

10. Tool (1) for a hydro cleaner machine according to claim 9, characterised in that at least one part of the conveyor conduit (5) is defined by a rigid distributor element (40), and said attachment seat (43) is obtained in said distributor element (40).

11. Tool (1) for a hydro cleaner machine according to claim 9, characterised in that said valve body (87) is partially inserted inside the external envelope (82) of the downflow conduit (80) so that it presents a first portion (87a) that intercepts the downflow conduit (80) itself, and a second protruding portion (87b) at which is obtained said insertion section (87c).

12. Tool (1) for a hydro cleaner machine according to claim 11, characterised in that inside the valve body (87), at the first portion (87a) are two tubes (89, 90) adapted to define a passage for the detergent towards the exterior, and which are connected through a port (91) on which acts the obturator (85a) of the valve (85) permitting or preventing the exit of the detergent.

13. Tool (1) for a hydro cleaner machine according to claim 12, characterised in that inside the valve body (87) at the second portion (87b) is a casing (92) which communicates with the conveyor conduit (5), inside which is contained the end section (85c) of the valve (85).

14. Tool (1) for a hydro cleaner machine according to claim 7, characterised in that said valve body (87) is a single body with the external element (82) of the downflow conduit (80).

15. Tool (1) for a hydro cleaner machine according to claim 1, characterised in that it comprises a regulating system (72, 73, 74, 74′

, 75, 77) for the amount of detergent that can be distributed.

16. Tool (1) for a hydro cleaner machine according to claim 15, characterised in that said regulating system comprises a penetrating element (74) adapted to be inserted axially inside the discharge mouth (71) of the container tank (7) thus reducing the passage section in a corresponding manner.

17. Tool (1) for a hydro cleaner machine according to claim 16, characterised in that said regulating system comprises a rod (73), one end of which is associated with said penetrating body (74) and activating means (72, 72a, 73a, 75) adapted to provoke the axial movement of the penetrating body (74) itself.

18. Tool (1) for a hydro cleaner machine according to claim 17, characterised in that said activating means comprise a threaded section (73a) of the rod (73) adapted to engage into a corresponding threaded hole (72a) of the container tank (7), and a knob (75), associated with the rod (73) and arranged on the exterior of the tank (7), adapted to be manually rotated to provoke the screwing/unscrewing of the threaded section (73a) relative to the threaded hole (72a) and thus, the axial movement of the rod (73) and the penetrating body (74).

19. Tool (1) for a hydro cleaner machine according to claim 18, characterised in that the discharge mouth (71) is vertically aligned with the filler mouth (70), which is equipped with a closure cap (72) which contains said threaded hole (72a).

20. Tool (1) for a hydro cleaner machine according to claim 17, characterised in that the discharge mouth (71) is vertically aligned with the filler mouth (70), which is externally threaded, and said activating means comprises a closure cap (72) also threaded and adapted to engage on the filler mouth (70) to which the rod (73) is integrally associated.

21. Tool (1) for a hydro cleaner machine according to claim 15, characterised in that said regulating system comprises:

an obturator body (74′

) adapted to engage with a corresponding connected seat (77) associated with the discharge mouth (71) of the container tank (7) in a manner so that said discharge mouth (71) is closed to the passage of the detergent;

said obturator body (74′

) and connected seat (77) presenting respectively a casing (76) and a recess (78) conformed in a manner so that for a determined angled position, the obturator body (74′

) results in a position facing the connected seat (77) thus defining a passage for the detergent towards the exterior;

a rod (73) one end of which is associated with said obturator body (74′

) and

activating means adapted to provoke the axial rotation of the obturator body (74′

) itself.

22. Tool (1) for a hydro cleaner machine according to claim 21, characterised in that said discharge mouth (71) is vertically aligned with the filler mouth (70), and said activating means comprise a closure cap (72) adapted to be engaged on the filler mouth (70) by means of a bayonet system, integrally associated to the rod (73).
