A shower head (1) is provided with safety cut out valve means for preventing emission of excessively hot water from the head (1). A valve member (30) for controlling or closing off water supply flow through the head (1) is operated by heat responsive means in the form of a flexible dished disc (33) or like disc assembly in contact with the water flow and which flexes on excessive water temperature to operate the valve member (30) relative to or against an opening or seating (31) to the spray head (10). The disc (33) is shown directly and centrally connected by a stem (32) to the valve member (30) which latter can be exteriorly operated e.g. by a button (4) for lifting against the action of the disc (33) such as for hand resetting the water temperature or over-riding delayed re-setting of the disc (33). The button (4) acts on a stem (34) from the valve member (30) which stem also slidable locates the latter relative to the seating (31). The whole safety valve assembly is shown contained in a hollow body (35) providing a valve chamber (3) and which communicates with the interior of the tubular handle (11) to receive water supply flow therefrom. |
