Abstract: A sprinkler for discharging liquid onto an area with a predetermined geometrically shaped perimeter while maintaining a substantially constant liquids precipitation over said area. The sprinkler comprises a housing fitted with a flow chamber accommodating a motor for rotating a sprinkler head mounted on the housing, the housing comprising a first nozzle and a second nozzle, in flow communication with the outlet end of the flow chamber. The first nozzle fitted for discharging liquid at a substantially short range. The sprinkler further comprises a dynamic liquid deflector associated with the second nozzle, and biased by an array of biasing elements, each adapted to dynamically bias the liquid deflector to a predetermined angle, thereby determine a deflection angle thereof.

Abstract: A sprinkler assembly comprising in combination a sprinkler mounting stake and a sprinkler comprising. The sprinkler comprises a sprinkler body formed with a support member receptacle and locking portion. The sprinkler mounting stake comprises a ground insertion portion and a sprinkler support portion. The sprinkler support portion comprises a lateral support member extending parallel to a longitudinal axis of the stake and retention member. The support member is insertable within the support member receptacle and a retention member prevents unintentional disengagement of the sprinkler body from the mounting stake.

Abstract: A liquid atomizer comprising a housing fitted with an inlet for connecting to a liquid supply line and a cavity being in flow communication with the inlet and having a longitudinal axis. The housing has one or more outlet nozzles for emitting atomized liquid. A vortex generating member is received within the housing and is formed with at lest one vortex generating path generates a liquid vortex about an axis transversally extending relative to the longitudinal axis of the housing and extending opposite a respective outlet nozzle. Each of the vortex generating paths is in flow communication with the cavity and extends opposite a respective outlet nozzle.

Abstract: A Strip irrigator comprising a body member fitted with an inlet for coupling to an irrigation water supply and an outlet nozzle of said body member, defining a longitudinal axis, a distribution member formed with a water engaging portion consisting of two ducts forming between them an essentially V-like shape with an intersection adjacent a lower end thereof, each duct ending at a deflection groove, and a support bracket pivotally supporting the distribution member to the body member. The arrangement being such that responsive to a water jet emitted from the outlet nozzle, the distribution member generates reactionary forces imparting it as a reciprocal rocking motion about a horizontal axis perpendicular to the longitudinal axis.

Abstract: A rotary sprinkler comprising a stationary housing, a distribution member rotatable with respect to said housing, a stationary fluid supply member being in flow communication with an inlet port of the housing and with the distribution member, and a sealing assembly, the sealing assembly comprises at least one sealing ring made of an essentially hard, abrasion resistant material, wherein one face of the sealing ring is rotationally fixed with respect to either the distribution member or one of the stationary housing and fluid supply member.
