A shower spray device comprises a head (1) including a chamber and fluid paths to supply water thereto, an outer wall (2) of the chamber being formed from a plurality of concentric spray rings (3,4,5), serrations (9,10,10a) formed in the wall of one ring defining in co-operation with the wall of an adjacent ring, apertures (9a, 11,11a) through which water is emitted; one of the spray rings (4) being movable with respect to a fixed adjacent ring (3) against a spring (8,14) contained in the head, the walls of the movable (4) and adjacent fixed ring (3) being angled relative to each other whereby movement of the movable ring in response to changes in inlet water pressure results in a change in size of the apertures (11,11a) defined therebetween to provide that the water pressure emitted through the apertures (11,11a,9a) remains substantially constant. |
