Irrigator with an oscillating arm
First Claim
1. An irrigator comprising:
- an oscillating arm, the oscillating arm comprising a hollow cylinder provided with a longitudinal succession of holes suitable for passage therethrough of an irrigation liquid;
an operation unit operable by the irrigation liquid suitable for oscillating the arm about its own axis;
a cylindrical sleeve inserted coaxially and rotatably in said oscillating arm, the sleeve having at least one surface groove thereon for channeling the irrigation liquid whereby the irrigation liquid is emitted through holes in the arm aligned with the surface groove, the sleeve having a terminal section and a remaining section, the groove having a terminal groove section in the terminal section of the sleeve and a remaining groove section in the remaining section of the sleeve;
wherein the terminal section of said sleeve is rotatable with respect to the remaining section of the sleeve, to allow the terminal groove section to be staggered with respect to the remaining groove section for controlling the flow of irrigation liquid from the oscillating arm.

Abstract
An irrigator comprises an oscillating arm (1) formed by a hollow cylinder provided with a longitudinal succession of holes (8) suitable for passage of an irrigation liquid. An operation unit (6) oscillates the arm about its own axis. A cylindrical sleeve (9) is inserted coaxially and rotatably in the oscillating arm, and has thereon at least one surface groove (11) for channeling the irrigation liquid whereby the irrigation liquid is emitted through the holes in the arm aligned with the surface groove. The sleeve has a terminal section (13) and a remaining section (12), and the groove (11) has a terminal groove section in the terminal section of the sleeve and a remaining groove section in the remaining section of the sleeve. The terminal section (13) of the sleeve is rotatable with respect to the remaining section (12) of the sleeve, to allow the terminal groove section to be staggered with respect to the remaining groove section for controlling the flow of irrigation liquid from the oscillating arm.
