ABSTRACT:
There is disclosed tub-shower diverter apparatus that includes a diverter chamber having a planar annular surface that is pierced by a first opening or openings to provide communication with an inlet water supply, and is further pierced by second and third oppositely disposed openings or series of openings that communicate respectively with a tub outlet and a shower outlet. The second and third openings are centered on a diameter of the planar annular surface and are spaced radially from the first opening. Diverter seal means disposed within the diverter chamber is an elastomeric washer sized to overlay the second and third openings, but not the first opening. A diverter cam underlies a portion of the elastomeric washer to prevent that portion from engaging the diverter chamber planar annular surface. Rotation of the cam permits selection of the portion of the elastomeric washer that will not be engaged with the diverter chamber planar annular surface. Pressure of water from the inlet supply will force the elastomeric washer into sealing engagement with the diverter chamber planar surface except where prevented by the cam. The cam can be positioned to selectively permit water flow to the tub or to the shower, or to neither. Additional aspects of the invention are also disclosed.
