Detergent dispenser for use with solid casting detergent

An improved detergent dispenser coupled to a source of fluid and having a chemical source being in solid cast form, a spray generator designed to generate a fluid spray bearing on the chemical source, the fluid spray generating a concentrated solution of the chemical, the concentrated solution of the chemical being discharged through a discharge conduit, wherein the improvement comprises:

• a valve for controlling the flow of a fluid from a fluid inlet to a first and a second valve outlet, the fluid inlet being in flow communication with the source of fluid and having a cylindrical valve body and a valve stem disposed therein, the cylindrical valve body defining a valve stem cavity and having the fluid inlet and the first and the second fluid outlets defined therethrough and opening into said valve stem cavity;
• and the valve stem having an exterior surface rotatably engaged within said valve stem cavity and having a semi circular fluid channel defined in said exterior surface,
• wherein rotation of the valve stem within the valve body selectively brings said fluid channel into registry with the fluid inlet and fluid outlets defined in the valve body, thereby opening and closing said fluid inlet and fluid outlets as desired.
