Improvements in a tankless toilet flush system is disclosed. The Flush-All-Tankless device is disclosed in two versions: First version has the water output at the bottom that has an All-split-lock coupler joint assembly to connect it to urinals or some toilet bowls with no water tank mounting holes (like in many commercial toilet bowls). The second version has a factory built in All-Mounting-Base at the bottom to connect it to the remainder of toilet bowl systems on the market which includes all the toilet bowls with water tank mounting holes like in most residential toilet bowls. For those who prefer the porcelain look, an All porcelain cover can be used. This system eliminates the need for a water tank and can be used on toilet bowls with a wall mounted tanks used in many countries. This way the wall mounted tank can be completely eliminated.

A flushometer system includes a valve body having an inlet, an outlet, and an actuation opening, a main valve seat assembly disposed in the valve body, a piston assembly slidably disposed within the valve body and configured for sealing the main valve seat assembly and moving to permit liquid to flow through the main valve seat assembly, and an actuation module engaged with the valve body. A relief chamber is defined between the actuation module and the piston assembly, and the actuation module is configured to vent the relief chamber upon actuation. The actuation module includes first and second plungers. The first plunger and the second plungers are moveable to vent the relief chamber, where the piston assembly moves to permit water to flow through the main valve seat assembly. Movement of the first plunger allows a larger flush volume to pass through the main valve seat assembly than movement of the second plunger.

The present invention discloses a hydraulic energy storage mechanism, including a cylinder block, a cylinder body, a piston, a support, and a latch bolt component. In the present invention, a cylinder body, a piston, and a support structure being provided with a power slide block is used, and the tap water pressure is applied to push the piston to compress a spring and converted into elastic potential energy; the power slide block is driven by releasing the elastic potential energy to operate a suction drainage device of a water closet. The present invention has advantages of a small volume, large acting force, a simple structure, and reliable working, and effectively improves sewage drainage efficiency of the water closet.
