Shower head has impeller (15) with vanes (16) and is driven by water pressure through jets (7) spaced around the head. A slider (9) around the rim of the shower head slides over radial outlets (17,18) at two different angles. In any position, sum total of output from any two jets is constant, while rotational speed of impeller changes. This ensures that pulsation effect of the spray jets is altered without altering the water flow rate. |
