    Abstract: A self-closing valve (14) for flushing drip-irrigation lines (10) at the beginning of every irrigation cycle. The valve (14) comprises a housing (16) defining an enclosed space, having an inlet portion (16c) mountable to the line end, allowing free communication with the water of the line (10). The housing (16c) comprises an elastic membrane (24) dividing the enclosed space into upstream and downstream compartments (S1, S2) with respect to said flow, with a passage communicating between the said compartments. A discharge opening (34) is formed in the upstream compartment (S1). Flow impeding means are associated with said passage (26) for restricting the flow of water from the upstream compartment (S1) into the downstream compartment (S2), said flow being effective to flex the membrane (24) in the upstream direction until it closes against the discharge opening (34).

    Abstract: Un aspersor giratorio incluye una carcasa y un núcleo móvil. El núcleo puede asumir estados retraído y extendido con respecto a la carcasa e incluye una cubierta, un miembro de impacto y un deflector de corriente. En el estado extendido, tanto la cubierta como el miembro de impacto pueden pivotar entre estados pivotados y no pivotados alrededor de una bisagra que define un eje H generalmente ortogonal al eje X y el deflector de corriente está fijado contra la rotación alrededor de la bisagra.
