Abstract
Abstract The apparatus comprises a passage for inflow of a fluid into a volume surrounded by a wall having a plurality of holes in it which admit the fluid to a second volume also surrounded by a wall having a plurality of holes in it in positions which are other than in the direct flow direction of fluid issuing from the holes in the walls surrounding the first volume. The preferred embodiment comprises two tubes, both closed at one end by a single closure component and the volume between them closed at the other end by a component which also incorporate an internally threaded passage for the inflow of fluid adapted to be screw connected on to a source of the fluid. The holes in the two pipes are staggered both axially and angularly in such a manner that if the angular staggering is carried out incompletely or not at all due to prior assembly during manufacture the axial staggering nevertheless provides that the holes of the two pipes are still in positions other than the direct flow direction.

Claim 1
Independent Claim

Apparatus for breaking up a directional water stream which comprises inner and outer concentric cylindrical walls, an inlet connector at one end of the inner wall providing a passage for the inflow of water into a volume surrounded by the inner wall, an end closure wall closing off the end of outer wall nearest the connector, and an end closure wall closing off the ends of the inner and outer walls opposite the connector, in which the inner and outer walls have a plurality of holes in them, the holes in the outer wall being in positions other than the direct flow direction of water issuing from the holes in the inner wall when in use, and in which holes in the inner wall near the connector are of larger size than holes in the inner wall near the end closure wall.

Apparatus for breaking up a directional water stream made from plastics polymer, which comprises exclusively: an inner circular cylindrical wall with two ends integrally incorporating an inlet connector at one end which provides a passage for the inflow of water into a volume within the inner wall, the inner wall having a plurality of holes in it, and an outer concentric circular cylindrical wall with two ends, integrally incorporating at the end opposite to the connector an end closure wall adapted to close off that end of both the volume within the inner wall and a volume between the inner and outer walls, the end closure wall having a formation on its inside face adapted to locate the end of the inner wall concentrically and facilitate sealing and assembly, and in which the end of the volume between the inner and outer walls opposite the end closure wall integral with the outer wall is closed off by the connector which also concentrically locates the outer tube, the outer wall having a plurality of holes in it in positions other than in the direct flow direction of water issuing from the holes in the inner wall when in use.
