    • 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.

    • A hose reel includes a support casing, a drum rotatably fitted inside the casing and connected to it by an elastic rewinding element. The drum provides a flange integral with it and couplable in rotation with a locking disc equipped with teeth engageable with opposing teeth capable of stopping its rotation. An elastic separator is provided between the flange and the locking disc to keep the latter in a first position axially distanced from the flange, teeth and counter-teeth mutually engaged to allow the flange to draw the locking disc into integral rotation with it, and cam and counter-cam which, in the event of the flange exceeding a predetermined threshold speed cause the axial displacement of the locking disc into a second position adjoining the flange in which its teeth engage with the opposing teeth to produce the consequent stopping of the rotation of said drum.

    • There is described a control device that allows to drive both AC solenoids and DC bistable solenoids. The control device comprises power supply terminals which may selectively be connected to an AC or DC voltage source, load terminals which may be connected to a driven solenoid, at least one triac device connected in series to said driven solenoid, means which may be controlled to switch on said triac. There are further provided selector means interposed between said power supply terminals and said load terminals to switch the control device between a first configuration suitable for the power supply of an AC solenoid and a second configuration suitable for the power supply of a DC bistable solenoid and inverter means which may be controlled to invert the voltage polarity at the load terminals with respect to that applied at the power supply terminals when the control device (1) is selected in said second configuration.
