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). In a further development an operating spindle has a co-axial hollow shaft (62) about it which can be releasably locked (70,73) to the spindle (32) and when they are so locked together the shaft (62) operates the ported valve member (60) with the on/off flow inlet valve such as a ceramic disc type valve (30) remaining inoperative i.e. during port selection. On release of the shaft (62) from the spindle (32) the latter can independently operate the on/off flow inlet valve (30) for admitting fluid flow to the ported valve member (60) and to the porting (66). The selector valve arrangement (4 or 6) may be received in a body (10) or body assembly (100) having passageways (15-17 or 113 and 114) for directing selected fluid flow to locations of use such as to shower heads or the like. |
