Abstract

A water sprinkling system for greenhouse comprises two horizontal rails and a carriage movably mounted to the rails. A fluid outlet disposed at a substantially midway point along the rails is connected to the carriage by a fluid transfer hose for guiding fluid to the carriage from the fluid outlet. The hose has a first end portion extending from the fluid outlet along the first rail, a second end portion extending to the carriage along the second rail, and a middle portion connecting the end portions to one another. Support elements, preferably in the form of hook members, are spaced from one another along the first rail for supporting the first end portion of the hose, while a plurality of roller members are spaced from one another along the second rail for rollably supporting the second end portion of the hose. A hosecar is movably mounted to the rails for carrying the middle portion of the hose. A cable provided for maintaining tension on the hose is operatively connected to the hosecar to exert thereon a force directed along the path of the rails and essentially directly opposed to a force exerted on the hosecar by the hose. Deflectors, preferably in the form of rollers, are provided on the hosecar for deflecting the hose from a first orientation occupied by the first end portion of the hose to a second orientation occupied by the middle portion of the hose and for bending the hose from one rail towards the other, so that the middle portion of the hose is disposed substantially perpendicularly to the first end portion and the second end portion.
