Claim Text:
1. A dispensing device for an underground sprinkler comprising a main tubular outer body, intended to be vertically buried underground, and an inner piston slidably inserted into said main tubular outer body and the inner piston being in connection with a water dispensing head provided with a diffusing unit, said piston being elastically held in a resting position with the water dispensing head lowered and displaceable to an irrigation position with the water dispensing head lifted by a pressure of the water supplied to a base of the main tubular outer body, said water dispensing head comprising a jet adjusting unit arranged in a position so as to be manually accessible from outside of the water dispensing head when said water dispensing head is lifted to the irrigation position, and said jet adjusting unit comprising a rotary annular intermediate body arranged in an intermediate position between an upper body supporting the diffusing unit and a lower body secured to the piston for moving the water dispensing head, said rotary annular intermediate body being provided with water-passing loops which, by changing an angular position of the rotary annular intermediate body, overlaps with or does not overlap with corresponding loops of the lower body to partially or completely open or close the passage of water from the base of said main tubular outer body to the diffusing unit, an insert being snap-fitted in said upper body, the insert having an annular peripheral wall and a circular intermediate cross-bar crossed by axial holes arranged circumferentially, the circular intermediate cross-bar dividing an inner space of the insert into a lower cavity and an upper cavity, said insert ending at a top in an annular neck with a central blind hole, which is inserted into an axial upper hole of said upper body so as to define an annular slit surrounding the annular neck.
