Abstract
A ballcock type flow-limiting valve for refilling a water tank and commode. A vertical riser has an internal inlet water passage connected to the valve base which has a recess surrounding the inlet seat forming a lower discharge chamber. A removable, dome shaped cap is secured to the valve base, overlaying the recessed area and forming an upper flow chamber. A vertical, free floating piston that controls inlet water flow and shut off is mounted slidingly through a central boss in the cap top and is actuated by an external pivoted arm. The piston and the lower discharge chamber incorporate features designed to limit water inlet flow to the discharge chambers and also to prevent accidental excessive movement of the piston. Provision is included to allow for possible valve blockages due to part swelling or water debris, and to ensure water flow access to the discharge passages for refill. The piston is accessible for servicing or removal by easy removal of the cap.
