<p>The operating mechanism (2) is shown consisting of a rotary actuating member or turbine wheel (20) driven by water flow through the shower head (1), the wheel (20) having a cam co-action (26, 61) with a plate (6) fixed in the shower head. The resulting axial oscillation of the wheel (20) is imparted to a closure or restricting stopper or plug (3) relative to an outlet opening (40) in an outlet plate (4) of the head (1), the plug (3) being carried by a shaft (23) from the wheel (20). Variable or pulsating water emission is thus effected from the opening (40). A rear perforated feed plate (5) directs water flow to the wheel (20) which is shown resiliently loaded to maintain the cam co-action by a compression spring (7) acting between the plate (5) and wheel (20) as in Figures 1 and 2. Positive two way cam operation of the wheel (20) is shown in Figure 3 by and between the feed plate (5) and plate (6). The plug (3) is screw adjustable (32) on the shaft (23) for variation of water emission and has a taper cooperation with the outlet opening (40).</p> |
