Abstract
A water valve having dual mechanisms for controlling the flow of water for both high pressure and low pressure applications. The first mechanism controlling the flow of water out of a first opening and the second mechanism controlling the flow of water out a second opening. The mechanisms work together to control the flow of water from a closed position to an open position.
Claims15
A water valve, comprising:
- a main body;
- a float arm;
- a first opening;
- a second opening;
- a piston;
- a lever;
- a sealing member;
- the float arm exerting a first pressure on the sealing member wherein the first pressure at least partially maintains the valve in a closed position;
- the piston exerting a second pressure on the sealing member wherein the second pressure at least partially maintains the valve in the closed position;
- the lever exerting a first force on a seal wherein the first force is sufficient to prevent flow through the second opening in the closed position;
- a primary fulcrum;
- the sealing member and the lever pivotable around the primary fulcrum.

A water valve, comprising:
- a body;
- the body having a first cavity and a second cavity;
- a passageway connecting the first cavity to the second cavity;
- a piston at least partially within the second cavity;
- the body comprising a first opening and a second opening;
- the piston exerting a first force on a lever;
- a float arm;
- the float arm exerting a second force on the lever;
- wherein the first force and second force together preventing a flow of a liquid through the first opening and the second opening when the valve is in a closed position;
- the piston comprises a tail;
- at least a portion of the tail movable between the first cavity and the second cavity whereby the tail can assist in cleaning debris in the valve.
