Flushing system for a pressurized toilet

Abstract

A toilet system including a bowl and a tank configured to hold water and air and deliver water to the bowl. The tank includes a water inlet and outlet. A valve moves between an open position and a closed position, and the valve closes the outlet when the valve is in the closed position. The system includes a lever positioned to engage the valve and a plunger that is configured to engage the lever. The tank includes a container that holds water and pressurized air above the water. The container is positioned such that the water and pressurized air in the container apply a force to the lever through the plunger which causes the lever to move the valve from the closed position toward the open position in order that water can flush and refill the toilet bowl and air can flow into the tank and container.

1 . A pressurized flush toilet system, comprising:
 a bowl;   a tank configured to hold water and to deliver water to said bowl, said tank including an inlet that delivers water into said tank and an outlet that allows water to exit said tank;   a valve being configured to move between an open position and a closed position, wherein said valve closes said outlet of said tank when said valve is in said closed position;   a lever positioned to engage said valve;   a plunger that extends out of said tank and that is configured to engage said lever, said plunger being movable with respect to said tank; and   a container configured to hold water and compressed air and being positioned in said tank such that water and compressed air held in said container apply a force to said plunger such that said plunger applies a force to said lever which causes said lever to move said valve from said closed position toward said open position.   
     
     
         2 . The pressurized flush toilet system of  claim 1 , further comprising a handle external to said tank, said handle being connected to said lever such that force applied to said handle is applied to said lever to cause said lever to apply force to said valve and push said valve out of said closed position. 
     
     
         3 . The pressurized flush toilet system of  claim 1 , wherein said inlet delivers water into said tank until the pressure of air and water in said tank prevents any more water from entering said tank. 
     
     
         4 . The pressurized flush toilet system of  claim 1 , further comprising a spring configured to resistably engage said lever and push said lever away from said valve. 
     
     
         5 . The pressurized flush toilet system of  claim 1 , wherein said container includes a hole on a side wall thereof that allows water and air to drain out of said container to reduce the amount of water and air in said container. 
     
     
         6 . The pressurized flush toilet system of  claim 5 , wherein as water drains out of said hole, the force applied by the water and the compressed air that remain in said container to said plunger causes said plunger to engage said lever such that said lever engages said valve to maintain said valve out of said closed position. 
     
     
         7 . The pressurized flush toilet system of  claim 6 , wherein after a certain amount of water drains out of said container, the force applied to said plunger by the water and compressed air in said container reduces to a point wherein said plunger no longer applies enough force to said lever to prevent said valve from moving to said closed position. 
     
     
         8 . The pressurized flush toilet system of  claim 1 , further including a base having a cavity that extends from said outlet to said bowl, said lever being positioned within said cavity and said plunger partially extending into said cavity. 
     
     
         9 . A pressurized flush toilet system, comprising:
 a bowl;   a tank configured to hold water and to deliver water to said bowl, said tank including an inlet that delivers water into said tank and an outlet that allows water to exit said tank;   a valve being configured to move between an open position and a closed position, wherein said valve closes said outlet of said tank when said valve is in said closed position;   a lever positioned to engage said valve; and   a container configured to hold water and compressed air and being positioned in said tank such that water and compressed air held in said container apply a force and at least a portion of that force is applied to said lever which causes said lever to move said valve from said closed position toward said open position.   
     
     
         10 . The pressurized flush toilet system of  claim 9 , further comprising a plunger that is movable with respect to said tank and that is positioned proximate said container such that water and compressed air in said container applies a force to said plunger such that said plunger applies a force to said lever. 
     
     
         11 . The pressurized flush toilet system of  claim 9 , further comprising a spring configured to resistably engage said lever and push said lever away from said valve. 
     
     
         12 . The pressurized flush toilet system of  claim 9 , wherein said container includes a hole on a sidewall thereof that allows water and air to drain out of said container to reduce the amount of water and air in said container. 
     
     
         13 . The pressurized flush toilet system of  claim 12 , wherein as water drains out of said hole, the force applied by the water and compressed air that remain in said container is applied to said lever such that said lever engages said valve to maintain said valve out of said closed position. 
     
     
         14 . The pressurized flush toilet system of  claim 13 , wherein after a certain amount of water drains out of said container, the force applied by the water and compressed air in said container reduces to a point wherein said lever no longer applies enough force to said valve to prevent said valve from moving to said closed position. 
     
     
         15 . A pressurized flush toilet system, comprising:
 a bowl;   a tank configured to hold water and to deliver water to said bowl, said tank including an inlet that delivers water into said tank and an outlet that allows water to exit said tank;   a valve being configured to move between an open position and a closed position, wherein said valve closes said outlet of said tank when said valve is in said closed position;   a container configured to hold water and compressed air and being positioned in the tank; and   a plunger that is moveable with respect to said tank and that is positioned proximate said container such that water and compressed air in said container apply a force to said plunger and at least a portion of that force is applied from said plunger to said valve to move said valve from said closed position toward said open position.   
     
     
         16 . The pressurized flush toilet system of  claim 15 , further comprising a lever that is positioned to engage said valve and said plunger, wherein said lever applies a force from said plunger to said valve to move said valve from said closed position toward said open position. 
     
     
         17 . The pressurized flush toilet system of  claim 16 , further comprising a spring configured to resistably engage said lever and push said lever away from said valve. 
     
     
         18 . The pressurized flush toilet system of  claim 15 , wherein said container includes a hole on a sidewall thereof that allows water and air to drain out of said container to reduce the amount of water and air in said container. 
     
     
         19 . The pressurized flush toilet system of  claim 18 , wherein as water drains out of said hole, the force applied by the water and compressed air that remain in said container to said plunger is applied to said valve to maintain said valve out of said closed position. 
     
     
         20 . The pressurized flush toilet system of  claim 19 , wherein after a certain amount of water drains out of said container, the force applied by the water and compressed air in said container reduces to a point wherein the force applies from said plunger to said valve is no longer great enough to prevent said valve from moving to said closed position.
