ABSTRACT:
A control device adapted for being connected to hot and cold supplies having a faucet control for selectively diverting the flow of water between two outlets and for regulating the rate of flow from the selected outlet independently of the hot and cold faucet controls comprising a hollow sleeve member having hot and cold water inlets and first and second outlets and a piston slidable in the sleeve for movement between first and second positions. In the first position a first outlet is blocked and the two inlets communicate with the second outlet and in the second position the second outlet is blocked and the two inlets communicate with the first outlet. The piston can assume an intermediate position in which both inlets are blocked and no water flows through the sleeve. As the piston moves from the intermediate position to either of the other positions, the inlets are gradually opened and the rate of flow increases through the inlets to the respective outlet depending upon the direction of movement of the piston.
