A flushing apparatus (1, 301) for being installed in the cistern of a toilet including a flushing device (2) for fluid connection with an outlet of a cistern and a hydraulically-driven control circuit (3, 303) for operating the flushing device. The control circuit (3, 303) includes a water inlet (P) for fluidly connecting the control circuit (3, 303) to a source of pressurised water and an accumulator (6) fluidly connected to the water inlet (P) and configured to supplement, in use, the flow of pressurised water supplied by the source trough the control circuit (3, 303) to activate the flushing device (2).

A toilet bowl pressure flushing system with shock wave flushing is a compact rigid unit made by a fixed connection of: a rigid body of a pressure module containing at least one gas hydraulic accumulator and one downstream flow tank connected by at least one connection opening; an overflow pipe; an automatic hydraulic valve module comprising a core, an inlet and outlet elements of the automatic hydraulic valve, where the inlet element of the automatic hydraulic valve is connected to the outlet of the flow tank and where the outlet element of the automatic hydraulic valve feeds into the overflow pipe. At the same time it comprises an inlet from the pressure water supply that feeds into the rigid body of the pressure module or into the automatic hydraulic valve module.

The present invention provides an improvement for toilet fixtures that reduces the amount of wastewater that splashes out of a toilet during its use. This reduction in splashing reduces the odor and unsanitary conditions that frequently occur on and around a toilet. Advantageously, the invention allows a user to temporarily change an existing fixture to function similarly to a urinal and then return the fixture to its function as a toilet for both liquid and solid waste removal.

The present invention is related with the bathroom furniture manufacturing industry, such as bathtubs, washbasin, bidets, toilets among others. Particularly it relates to the manufacture of toilet bowls with a structure that allows for proper cleaning of the inside of the toilet when it is finished using, dragging efficiently solid and liquid wastes. Structurally the present invention consists of a toilet bowl with flux for a waste dragging, characterized by comprises a distribution chamber with an inlet at the top and two outlets, one in the front side wall and the other in the bottom wall; The outlet of the lateral wall conducts the flow of water into the rim, wherein said flow is distributed in 28 ellipsoidal holes throughout the periphery, on the underside thereof; The outlet of the lower face of the distribution chamber ends in two branches that surround the interior, the wall of the pot to reach the flow, which is the outlet of the jet that will push the waste towards the exit of the trap water.

A flow diverter for diverting flow between a toilet bowl and a toilet tank, having: a body having an inlet, a first outlet and a second outlet; and a flow adjustment mechanism rotatable within the body to selectively divert different percentages of flow between the first outlet and the second outlet; and an air vent and diaphragm in the body to prevent a siphon flow from the first or second outlet back to the inlet.

A fill valve assembly (9, 109) for connection with a flushing syphon or other flushing valve. The assembly (9, 109) includes a float operated equilibrium valve (90, 190) and a branch element (92, 192) fluidly connected upstream the equilibrium valve (90, 190) and including an outlet (98) for providing fluid flow to one or more fluid pressure driven actuators (6).

A pneumatic drain valve driving device includes a cylinder, including a cylinder body and an air chamber. The air chamber includes an air chamber communication port in air communication with an outside of the cylinder body; and an air chamber exhaust port configured to be connected to a pneumatic drain valve. The cylinder also includes a liquid chamber, including a drain hole configured to receive a slide valve. The cylinder also includes a piston disposed in the cylinder body. The device also includes a pilot valve, connected to the liquid chamber through a waterway and including a pilot valve control port. The device also includes a linkage trigger mechanism disposed between the pilot valve control port and the slide valve and configured to control an opening and a closing of the pilot valve control port and the slide valve.

A method of flushing a siphonic toilet that includes retaining a first volume of water in a bowl and an up leg of a passageway that is upstream from a dam, retaining a second volume of water in the passageway between a valve and the dam in a closed position of the valve, activating a flush cycle of the toilet that introduces a third volume of water into the toilet, and moving the valve from the closed position to an open position to affect a siphon during the flush cycle.

A control system for a cistern, the control system comprising a user activated sensor (13), a controller (14), a pump (15) and a pneumatic line (16) connected to the pump (15) and adapted to be connected to the drain valve (11) of a cistern (10), wherein the user activated sensor (13) and controller (14) are adapted to interpret a plurality of signals and operate the pump (15) in a pre-defined manner associated with a detected signal, thereby enabling a plurality of flushing actions to be effected using a single user activated sensor.

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.
