Apparatus for controlled release of an erodible solid into a liquid

A dispenser assembly for controlled hydro-injection release of an erodible solid cartridge into a liquid comprising:

• a fluid flow member having an inlet for attaching to a pressurized fluid line and an outlet;
• a hydro chamber provided in the fluid flow member, the hydro chamber having a hydro-injector member positioned therein;
• the hydro-injector member having an inlet opening which faces the inlet of the fluid flow member and outlet opening;
• the hydro-injector member has a rotatable valve, the rotatable valve has a first flow chamber and a second flow chamber;
• a cartridge holding member removably attached to the fluid flow member, the cartridge holding member configured to house the erodible solid cartridge in an activation chamber;
• a plate positioned in engagement with the hydro-injector member, the plate is a venturi plate having an opening which extends through the venturi plate, the opening is provided proximate a center of the venturi plate and is in alignment with the outlet opening of the hydro-injector member;
• wherein the hydro-injector and the plate control the rate of erosion of the erodible solid cartridge.
