Abstract: A watering nozzle (16) for underground pop-up sprinkler (1) comprises a bottom part (17) and a top part (37) comprising a distribution cylinder (40). The bottom part (17) is provided with an annular opening (100) that receives the flow of water coming from the base of the sprinkler (1) and generates a jet in the form of a spray having pre-established angular extension that flows into a distribution cylinder (40) provided with radial slots (41) arranged as an arc of circumference that proceed from its bottom to its side wall so as to subdivide the single spray jet into single jets. The distribution cylinder (40) has on top a fan wheel (70) having a diameter greater than the cylinder and provided with external fins (71) that extend downward.

Abstract: A rain sensor is described comprising a tray for the collection of rain water provided on top with evaporation and overflow side windows covered by a perforated cover. A finned float is housed in said tray so as to be able to move vertically as a function of the level of the water present in the tray. A permanent magnet supported by said float cooperates with an electric magneto-sensitive switch that is fixed to the tray in order to switch it between a first and a second electric state as a function of the vertical position of the float.

Abstract: An electronic control device for a bistable solenoid valve, particularly for watering systems. The control device includes a power supply battery and a logic control unit, and provides low battery protection. A capacitor is set in parallel to the battery and a switch is operated by the logic control unit to effect, in a first operating position, charging of the capacitor and, in second and third operating positions, the application of control voltages having opposite signs from the capacitor to the solenoid valve for closing and opening the solenoid valve. The logic control unit is programmed in such a way that each request for opening of the solenoid valve brings about first the setting of the switch in the first operating position for charging the capacitor, then the switch is activated in the second operating position for closing the solenoid valve after a first preset time has elapsed following any previous closing control of the solenoid valve.

Abstract: A control solenoid for solenoid valve, in particular for the control of watering systems, comprises a permanent magnet, an electric coil for the excitation of said magnet, a sliding piston for the control of the valve subject to the magnetic field produced by the magnet and electric connections of the solenoid to a control unit of the solenoid. The electric connections are made of “faston” type quick insertion connectors. The solenoid is made in two parts, a first internal part including the piston and the magnet is screwable onto the external casing of the solenoid valve and a second external part including the electric coil and the electric connectors is fixed to the first one in a removable way by a removable and re-insertable locking element.

Abstract: A solenoid valve is described comprising a hydraulic valve a valve body in which said hydraulic valve is housed and a control solenoid for said valve.

Abstract: A spray nozzle for pop-up underground sprinkler comprises a main fixed body and a revolving ring nut that is associated with the aforesaid main body in order to allow the adjustment of the spray angle. The main body and the ring nut as a whole create an area for the containment of water that communicates with the outside through an adjustable scroll-shaped radial passage. The ring nut in addition forms in communication with the aforementioned area an accumulation chamber in which the water flow is subject to compression for the formation of a uniform output spray.

The programmable processing unit is organized to individuate a programming menu that is subdivided into a plurality of parts selectionable at will. Each part comprising at least one chapter. The chapter being formed of at least one setting page of at least one respective programming parameter, and in that each part of the menu is directly selectionable by pressure on at least one respective operating button.

Abstract: An electronic interface associable to an electronic control unit for an automatic watering system for remote controlled management of the watering system is described. The electron unit has a plurality of output lines suitable to control a respective plurality of electro-valve lines of the watering system. The electronic interface includes a microprocessor, a connector for connecting the electronic interface with the watering system, a first interface with at least one communication channel having a remote controlled management apparatus, a second interface with a first plurality of input lines connectable with respective output lines of the control unit to control directly the electro-valves, and a first memory associated with the microprocessor in such a way that the microprocessor can detect the changes of state of the output lines of the control unit and store the changes of state in the first memory.

Abstract: A control unit for an irrigation system comprising a programmable electronic control unit having a plurality of output control lines for the control of actuators of the irrigation system and comprising a microprocessor for setting data that condition the operation of the control unit. The microprocessor is operable to allow a standard programming of the electronic control unit for setting data suitable for allowing the base operation of the control unit, and an advanced programming for setting further data suitable for customizing the base operation of the control unit.

Abstract: An electronic control unit for the control of automatic watering systems having plural lines comprising an electronic circuit with a programmable processing unit for the control of a plurality of different watering lines. A manually operated selector, preferably of the rotary type, is provided, that is settable in a plurality of selectionable positions, to each one of which a specific watering cycle for the lines corresponds. By acting on the selector and on a start button, it is possible to modify the programming of the processing unit in order to associate with each single line a respective watering cycle different from the ones otherwise selectable by means of the selector.

Abstract: There is described a programmable electronic timer for the control of a solenoid valve, particularly for watering systems. The timer comprises a start button, a stop button and a programmable processing unit. The latter is preset to determine, as a consequence to the operation on said start button, the opening of the controlled solenoid valve and the starting of a time count and, as a consequence to the operation on said stop button, the closing of the solenoid valve and the end of said time count with memorisation of the counted time for the subsequent automatic control of the opening and closing of the solenoid valve in the next days at the same time and for the same watering length of time.
