Abstract: A dispenser (1) for a liquid product (P) containing a film-forming polymer in the form of fine droplets, includes a container (2) containing the product (P) and at least one propellant gas (G). A valve (15) for dispensing the product, mounted on the container (2), includes a body (24) provided with a first chamber (28a) and a second chamber (28b), intercommunicating via a passage (p), movable element (16) for actuating the valve (15) being provided for the dispensing of the product, the first chamber (28a) being provided with a first additional gas intake opening (d1), and a second opening (d2) for the intake of the product in permanent communication with this product, the second chamber (28b) at least partially formed of the actuating element (16). In this valve, the delivery rate during the dispensing of the product (P) is determined by the cross-section of the passage (p).

Abstract: A valve (1), particularly for an aerosol container, includes, inside a valve body (2), an inlet passage (4) communicating with the container and an outlet passage (10), a first elastic return (16) for urging the valve (1) into the closed position, and a regulator for regulating the product outlet flow rate, which includes a second elastic return (14) for supplying a set-point pressure for the regulator. The second elastic return (14) is arranged in a compartment (12) of the valve body (2) isolated from the product, the pressure inside the compartment (12) being equal to atmospheric pressure.

Abstract: A wobbling sprinkler head is provided, especially for use in irrigation systems such as self-propelled mechanically moving irrigation systems, in which the wobbling sprinkler head faces downward from the water supply conduit. The sprinkler head has a body having a water inlet as well as an attachment for connection to the water supply and a nozzle for directing a stream of water from the sprinkler body. The sprinkler head has one or more arms extending from the body around a water deflecting head. The water deflecting head is movably attached to the sprinkler head body and has a water deflecting surface positioned to deflect water from the nozzle and move the water defecting head. The bottom of the water deflecting surface has a protruding member extending therefrom, for interacting with a second protruding member extending from the arms of the sprinkler head body. The protruding members can have magnets of opposing polarity mounted therein.
