A nozzle apparatus (10) comprising: an inlet, an outlet, a filter (20) disposed between the inlet and the outlet, and, a container (40); wherein the nozzle apparatus defines a first flow path for particles too large for said filter and a second flow path towards the outlet for particles small enough for said filter; and wherein the container (40) is provided downstream of the first flow path. In this way the pressure on the container downstream of the first fluid path causes the debris to accumulate therein and the nozzle is less liable to blockages. To facilitate this, the size of the inlet may be the same size or bigger than the size of the flow path between the screen and the container. The container is normally removable and reattachable e.g. from the filter to remove debris. The filter may also comprise apertures and these may be of a size equal to or smaller than the outlet of the nozzle apparatus downstream of the second flow path. In this way, the outlet is less liable to being blocked by debris which is can pass through the aperture(s) in the filter. The apparatus is of particular use as a sprinkler system. |
