Abstract: 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.

Elastic separation means (10) are provided between the flange (4) and the locking disc (5) to keep the latter in a first position axially distanced from said flange (4), teeth and counter-teeth means (51, 52) mutually engaged to allow the flange (4) to draw the locking disc (5) into integral rotation with it, and cam and counter-cam means (6, 7) which, in the event of said flange exceeding a predetermined threshold speed cause the axial displacement of said locking disc (5) into a second position adjoining said flange (4) in which its teeth (8) engage with said opposing teeth (9) to produce the consequent stopping of the rotation of said drum (3).

Abstract: A liquid spraying pistol for gardening including an external casing passed through by a channel within which a valve is slidingly housed which is biased by a spring and is operable by a start lever which is turnable between a closing position and a maximum opening position of said valve and a device for the locking/unlocking of said lever in the maximum opening position. The device is made up of a button elastically supported by the lever in such a way as to be able to provide, with the lever in the maximum opening position, a locking engagement between the lever and the external casing.

Abstract: A liquid spraying pistol with variable jet is described, which is made up of a handle (1) comprising a start lever (2) and a channel (4) in which a valve (3) is slidingly housed which is operated by said start lever (2), and a jet dispensing pipe (5) comprising an internal channel (7) communicating with said channel (4) of the handle (1) and an external casing (6) bearing a diffuser (9) placed at the output of said internal channel (7). Said diffuser (9) is axially movable with respect to said internal channel (7) of the dispensing pipe (5) in order to modify the shape of the jet and at the inlet of said internal channel (5) a body is arranged which is turnable around its axis in order to vary the communication between said channel (4) of the handle and said internal channel (7) of the dispensing pipe. (FIG. 2).

Abstract: A liquid spraying pistol is described, in particular for gardening, comprising an external casing (2) passed through by a channel (5) within which a valve (7) is slidingly housed which is biased by a spring (16) and is operable by a start lever (4) which is turnable between a closing position and a maximum opening position of said valve (7) and a device for the locking/unlocking of said lever (4) in maximum opening position. Said device is made up of a button (9) elastically supported by said lever (4) in such a way as to be able to provide, with the lever (4) in maximum opening position, a locking engagement between said lever (4) and the external casing (2).

Abstract: A device for the distribution of water into vases or similar objects. The device includes a water container, at least one tubular duct for the delivery of water to the outside and a control and programming device that establishes the quantity of water to be distributed in pre-established periods of time. The device for the distribution of water has a device for the control of the pressure of the quantity of water to be distributed that can keep the pressure of the quantity of water substantially constant, and an electric control delivery device located downstream of the device for the control of the pressure, upstream of the at least one tubular duct, and in flow connection with both. The delivery device is associated with the control and programming device in order to determine the delivery of the quantity of water.

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: 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.
