Abstract
An underground sprinkler of the pop-up type, comprising a main tubular outer body, intended to be vertically buried underground, and an inner body or moving piston slidably inserted into said main body, includes a water dispensing head provided with a diffusing unit at the top of said inner body or piston. The above-mentioned moving piston is typically elastically held in a resting position with its head lowered, and it is displaceable to the irrigation position with its head lifted by a pressure of the water supplied to the base of the main body. The dispensing head comprises a jet adjusting unit arranged in such a position as to be manually accessible from the outside when said head is lifted to the irrigation position.
