Abstract: An oscillating lawn sprinkler includes a watering pipe provided with spray nozzles and a choking device for selectively limiting the watering range of the sprinkler. The choking device includes a control member, an external manual-actuation device and an internal flow-diverting element. The internal flow-diverting element is capable of being oriented, through angular displacements of the control device, in corresponding positions for diverting the flow of water coming from a water inlet opening in such a manner as to deliver the water to all of the spray nozzles in the watering pipe, or to parts of the nozzles provided in opposite length portions of the watering pipe located on opposite sides of the flow-diverting element.

Abstract: A quick-release plug-in coupling device includes a female member to be connected to one hose and including a body, a valve seat internally of the body, and at least one opening through the body. A male member to be connected to another hose includes a body sealingly fittable into the body of the female member, the male member body having formed therein at least one recess. A valve member is positioned within the female member for movement between closed and opened positions relative to the valve seat. At least one actuating member is positioned outwardly of the female member and has an integrally formed elastic member extending inwardly through the opening in the body of the female member. The elastic member has an inner end fittable into the recess in the body of the male member. The actuating member is selectively manually movable axially of the female member between locking and release positions.
Abstract: An oscillating sprayer for spraying water on surrounding areas including a cylindrical main body and a support for rotatably supporting a lower part of the main body. An inclined nozzle extends radially outwardly and upwardly from the main body and an adjustable water stream deflector is disposed on the main body for adjusting the height of a water stream ejected from the nozzle by intercepting the water stream at a plurality of points spaced from the main body.
