Abstract
A pilot fill valve includes a float that is separated into upper and lower cavities by an angled partition through which a drain outlet and an overflow outlet are disposed. When the level of the float drops, a portion of the water supplied to the fill valve is diverted to a tank to raise the float, while the remainder is diverted to the upper cavity increasing the weight of the float. As the float begins to rise, the water in the upper cavity drains through the drain outlet and overflow outlet, making the float lighter, and causing the float and pivot arm to rotate with increased velocity, allowing the pilot cap carried by the pivot arm to fully shut off the valve.
Claims18
A float assembly adapted to be attached to a pivot arm of a pilot fill valve, the pilot fill valve having an outlet port extending therefrom that supplies water to a diverter attached to the pivot arm, the float assembly comprising:
- a float divided by an angled partition sloping upward from a first edge to a second edge to form first and second cavities;
- an overflow outlet disposed through said partition proximate to said second edge;
- and
- a drain outlet disposed through said partition between said first edge and said overflow outlet.
A pilot fill valve comprising:
- a fill valve body having a rotating pivot arm with a diverter configured to divert water received from a outlet port;
- and
- a float attached to said pivot arm, said float divided by an angled partition sloping upward from a first edge to a second edge, to form first and second cavities, said first cavity configured to receive diverted water from said outlet port, said float comprising:
- an overflow outlet disposed through said partition between said first edge and said second edge;
- and
- a drain outlet disposed through said partition between said first edge and said overflow outlet.
