A water turbine and electric motor hybrid power suction type water-saving toilet, with toilet main body comprising a hollow frame, a hollow frame water inlet, a basin bottom water injection hole and an S-shaped bend, wherein the hollow frame is located on upper part of the toilet with water injection holes distributed along the periphery towards inner side of the toilet; the hollow frame water inlet is formed in rear part of the toilet; the basin bottom water injection hole is formed in lower part of the toilet and communicates with the hollow frame water inlet through a pipe cavity attached to outer wall of the toilet; and a basin bottom water injection valve is arranged at the opening of the basin bottom water injection hole leading to the S-shaped bend and controls connection/disconnection of basin bottom water injection hole and S-shaped bend inlet section with water pumping process synchronously.

A flush valve apparatus comprising a main body, an outer cover, an inner cover, a valve assembly, and a back-pressure chamber, wherein the outer cover is coupled to an upper end of the main body, the inner cover is positioned over the valve assembly and under the outer cover, the valve assembly comprises a valve body and is positioned at an interior of the main body, the back-pressure chamber is defined by a lower surface of the inner cover and an upper surface of the valve assembly, and wherein one or more springs are positioned substantially vertically in the back-pressure chamber. The one or more springs are effective towards minimizing flush water variation between flush cycles and towards attenuation flush valve erratic behavior.

A pressurized tank assembly and method. The pressurized tank assembly may include a first siphon tank, a second siphon tank, an inlet assembly, and a discharge assembly. The first tank and second tank may be arranged vertically within the base of the toilet. The first tank and the second tank may be arranged with endcaps located at the top of each tank. The first tank and the second tank may include siphon tubes to assist in delivering fluid flow from the inlet assembly to the discharge assembly.

A plumbing fixture system comprising a plumbing fixture bowl and a trapway fluidly coupled with the plumbing fixture bowl. The plumbing fixture system further comprises a Venturi device comprising an inlet and an outlet. The Venturi device forms an interior volume. The Venturi device further forming a channel from the inlet to the outlet. The interior volume is fluidly coupled to the channel. Liquid flow from the inlet to the outlet causes a first reduction in pressure in the interior volume. The plumbing fixture system further comprises a conduit extending from the interior volume of the Venturi device to the trapway. The first reduction in pressure in the interior volume of the Venturi device causes a second reduction in pressure in the trapway.

A dual water-vessel flush structure and a pressure-assisted toilet flush system are disclosed. The dual water-vessel flush structure includes first and second vessels and a communicating pipe. The first vessel at an upper part thereof is provided with a water supplement hole and an air supplement hole. The second vessel at a lower part thereof is provided with a water outlet. The first and second vessels are mutually communicated at bottoms of laterals thereof through the communicating pipe. The pressure-assisted toilet flush system includes a dual water-vessel flush structure, a water-air supplement mechanism, a water drainage mechanism, and a control mechanism. The water supplement hole and the air supplement hole both lead to the first vessel through the water-air supplement mechanism. The water drainage mechanism is configured at the water outlet and interacts with the control mechanism.
