Claim 2:
3. A liquid-emitting device (1) for gravity-based irrigation systems, comprising:
a support structure (2) that defines a first longitudinal axis (X1) and has a nozzle (3) for generating an irrigation jet (J) coaxial with said first longitudinal axis (X1);
a tubular body (5) located below said support structure (2);
a circular baffle plate (6) facing said nozzle (3) and rotatably mounted in said tubular body (5) to rotate about a second longitudinal axis (X2),
wherein said liquid-emitting device (1) is a nutating device in which said circular baffle (6) is rotatable about said second longitudinal axis (X2) and has a precessional motion about said first longitudinal axis (X1), and
wherein said first longitudinal axis (X1) and said nozzle (3) are stationary relative to said support structure (2), said second longitudinal axis (X2) being free to rotate about said first longitudinal axis (X1) with said precessional motion;
a guide (12) designed to be removably coupled to said tubular body (5) to interact with said baffle plate (6) and prevent said precessional motion about said first longitudinal axis (X1) while allowing a rotational motion about said second longitudinal axis (X2); and
a diverting member (13) removably placed downstream of said nozzle (3) to direct the irrigation jet (J) over a sector portion (14) of said baffle plate (6) and distribute the liquid over a sector area of a soil,
wherein said diverting member (13) has a plate-shaped connecting portion (15) for connection to said support structure (2) and a beak-shaped channeling portion (17) with an elongate outlet opening (19), and
wherein said outlet opening (19) has two straight branches (19A, 19B) that are inclined toward each other, one of said two straight branches (19A) having a greater cross section than a second one of said two straight branches (19B) to create a shaped jet (J).
