摘要： A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel, the at least one jet channel having an inlet port and a jet outlet port configured for discharging fluid to a sump area, wherein the sump area is in fluid communication with a trapway. The bowl has a closed jet pathway including the jet channel and extending from the jet flush valve assembly outlet to the jet channel outlet port to maintain the jet channel in a primed state with fluid from the jet flush valve assembly so as to assist in preventing air from entering the closed jet pathway. Flush valves are also disclosed having back-flow preventer mechanisms and/or at least partly flexible valve covers for use with the toilet systems and methods herein.

摘要： 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 having a seal pivots between an open position and a closed position where the seal closes the outlet. A lever positioned outside of the tank pivots to push the valve out of the closed position and towards the open position such that the outlet is opened and water flows out of the tank into the bowl. The valve rotates to the open position as water flows from the tank until the weight of the seal causes the valve to pivot back to the closed position. A plunger extends into the tank and applies a force that pushes the valve away from the closed position to the open position.

摘要： A flush toilet is configured to permit user control of a flush cycle time and corresponding water usage. The toilet includes a bowl and a tank in fluid communication with the bowl. A flush handle assembly may be carried by the tank and may have a flush handle and a lever arm coupled thereto. In addition, there may be a flapper valve in the tank, and a rigid, adjustable-length, flapper control rod coupled between the lever arm and the flapper valve. Operation of the flush handle in a first direction may open the flapper valve, and operation of the flush handle in a second direction may close the flapper valve. This permits user control of the flush cycle time and corresponding water usage.

摘要： A water saving device for a toilet adapted for mounting on an overflow tube above a flapper valve. The device uses a mainframe connected to the overflow tube to position a highchair that is pivotally mounted to the mainframe. A water cup is mounted to the highchair for weight and a vertical cam descends from the highchair to contact and close the flapper valve.

摘要： A clutch assembly is provided for coupling a drive shaft with a drive arm of an actuator for use with an automatic toilet flushing system, wherein the drive shaft is adapted for rotation via a motor in the actuator. The clutch assembly includes a rotatable body extending between the drive shaft and the drive aim and having a first engaging member. A clutch disk is secured to the drive shaft and includes a second engaging member adapted for cooperating with the first engaging member of the body. A fastener secures the clutch disk to the drive shaft and a biasing member is provided for biasing the body toward the clutch disk. The body is adapted to overcome the biasing force of the biasing member should a predetermined torque on the drive shaft be exceeded to disengage the first and second engaging members and prevent damage to the drive shaft.

摘要： Improvements in a toilet flapper that is formed from an assembly of stainless steel components. The flapper includes hinge pivoting arms, the main body and the float as an integrated assembly. The integrated assembly is made from stamped and formed thin stainless steel sheet metal components that provide sufficient buoyance to allow the flapper to open and close. The toilet flapper made from stainless steel for the float to be sufficiently sized to fit within the throat of the drain pipe and also provide sufficient buoyancy for operation. The toilet flapper made from stainless steel for the flapper to remain flat. The seat remains flat because the stainless steel is essentially not affected by chemicals or age. The stainless steel is preferably 300 series and more preferably 304 stainless, but other types will provide similar sealing and structural functionality.

摘要： Flush valve assemblies are provided that include a valve body which may have a radiused inlet portion, an upper inlet end having an inlet opening, a lower outlet end having an outlet opening, and a wall extending between the upper inlet end and the lower outlet end and having an interior surface defining a flow path that extends generally longitudinally through the valve body from the inlet opening to the outlet opening and that has a generally circular transverse cross-section. A height measured longitudinally through the valve body is greater than a largest diameter of the transverse cross-section of the flow path so as to enable the valve bodies herein to have an elevated wall and head from a toilet tank floor. The assemblies may include a flapper valve cover detachably connected to the flush valve assembly and having a transverse cross-sectional diameter sufficiently large to cover the inlet opening of the valve body, a pivot mechanism and a flapper bulb. The flapper valve cover is sufficiently buoyant so as to be capable of resisting the force of flowing water and remain open so as to allow flush water to pass through the valve body when the valve body is installed on a toilet having a flush volume of about 1.6 gallons per flush or less before closing the valve cover so as to be useful in high performance, and also in high-efficiency toilets.
