  • Patent number: 6799604
    Abstract: A selector valve arrangement (4 or 6) primarily for a shower bath unit comprises a radially directed and angularly movable flow directing ported valve member (40 or 60) within a valve chamber (41 or 61) having ports (45-48 or 63-65) with which porting (44 or 66) of the valve member (40 or 60) selectively communicates on appropriate rotational positioning of the valve member (40 or 60). The valve member (40 or 60) receives fluid (usually water) for distribution through a selected port or ports (45-48 or 63-65) from an on/off fluid flow control inlet valve (43 or 30). In one arrangement a spindle (42) for rotating the valve member (40) is also axially operable and releasably lockable (49, 50) for operating the on/off flow valve (43).

  • Patent number: 6648245
    Abstract: The operating mechanism is shown consisting of a rotary actuating member or turbine wheel driven by water flow through the head, the wheel having a cam co-action with a plate fixed in the shower head. The resulting axial oscillation of the wheel is imparted to a closure or restricting stopper or plug relative to an outlet opening in an outlet plate of the head, the plug being carried by a shaft from the wheel. Variable or pulsating water emission is thus effected from the opening. A rear perforated feed plate directs water flow to the wheel which is shown resiliently loaded to maintain the cam co-action by a compression spring acting between the plate and wheel as in FIGS. 1 and 2. Positive two way cam operation of the wheel is shown in FIG. 3 by and between the feed plate and plate. The plug is screw adjustable on the shaft for variation of water emission and has a taper cooperation with the outlet opening.
