  • Patent number: 9702131
    Abstract: The invention relates to a discharge selector for water-closets, that allows the control of the discharge of water from the cistern of the water-closet into the bowl, in two different proportions, which allows less water to be used when liquids are to be removed from the bowl and a larger proportion of the content of the cistern to be discharged when solids are to be removed from the bowl. Said device consists of a single part provided with mechanisms that allow it to operate in the described manner and also allows the quantity of water discharged to be adjusted within a certain range. The device is universally applicable and does not leak water even if the packaging loses elasticity. The device can be installed by the user thereof as the installation is just as easy as that of the replacement flap in any currently commonly used discharge valve.

  • Patent number: 6742194
    Abstract: A dual-flush flapper valve assembly, set for a normally short flush, is provided for use with a pivoting flapper valve in a flush tank. The assembly comprises a weight, which moves back and forth along a guide relative to the flapper's pivot point. The moveable weight, if activated, temporarily reduces the turning moment arm of the flapper for ensuring a long flush. The assembly further comprises an actuator to trap and release the weight, resulting in either a short flush (when the weight is remote from the pivot) or a long flush (when the weight is close to the pivot). The flapper assembly is engageable through a resistance force, for selectively triggering the actuator, shifting the weight and resulting in a long flush. After a long flush the assembly resets for a short flush, until activated once again.

  • Patent number: 6467101
    Abstract: A toilet flushing and cleaning device includes a reservoir with a cylinder and a mixing tube disposed therein. The cylinder communicates with a water source. A plunger is slidably disposed in the cylinder. A plurality of spray nozzles communicate with the mixing tube. When a flush valve is opened to allow water into the cylinder, the piston is driven upwards. The increase in air pressure drives pressurized air and water into the mixing tube such that the spray nozzles clean the toilet with a burst of air-water mixture. In a further embodiment, a funnel is disposed in the toilet bowl and a bucket is suspended at the lower opening of the funnel. When the piston is driven upwards, the bucket is pivoted to release its contents. Additionally, a blower disposed between the funnel and the toilet bowl may be used to drawing air and odors from inside said funnel and directing air into said toilet bowl for release through the existing drain pipe and vent pipe.

  • Patent number: 6401269
    Abstract: A flapper valve assembly for regulating the passage of water from a toilet tank is provided with a structure to reduce overflow risk. There is a yoke pivotally disposed in the tank and supporting a flapper seal that can be seated on and unseated from the flush opening. A flapper arm has a first segment coupled to the yoke along a pivot axis and a second segment extending away from the pivot axis toward the flapper seal. The flapper arm is configured such that it delays seating of the flapper seal when the water in the tank is above a predetermined level and assists seating of the flapper seal when the water is below a designated level.

  • Patent number: 4979241
    Abstract: A patented valve control for use in a toilet tank having a bottom outlet for discharging water to a toilet bowl, a valve for closing the outlet, a conventional actuating lever and a chain connecting the lever to the valve for opening the latter, includes an arm carrying the valve pivotally mounted in the toilet tank for actuation by the chain to open the bottom outlet, a float on the arm biasing the valve to the open position when the tank is full and biasing the valve to the close position when the tank is empty, and a drainable container on the arm biasing the valve open when the latter is open and biasing the valve closed when the latter is closed. The amount of water discharged through the outlet during each flushing operation can be reduced by mounting a flush control device on the arm of the valve control. The flush control device is a rectangular parallelepipedic body with a groove in one side thereof for mounting the body on the arm.

  • Patent number: 4907302
    Abstract: An improvement is provided for toilet flush valves on tanks which contain insufficient water to flush properly, which leads to waste of water by double flushing. The improvement enables in-field modification of the flush valve to substantially completely empty the tank. A closing delay device (42, FIG. 1) which includes a cup (64), is attached directly to the top of the tank ball (32) for easy installation, and is tall enough so that when the tank ball is pivoted to the fully opened position the cup is pivoted to a side of the pivot axis (28) opposite the tank ball to delay closing of the flush valve. The tank ball is formed of soft rubber and has an upwardly extending tubular extension (74) with an annular groove therein, which closely receives an annular flange at the bottom of the delay cup device.

  • Patent number: 4296505
    Abstract: The amount of water discharged from the tank of a flush toilet is controlled in a stepless manner by means of a rotary volume control lever concentric with the usual flushing handle. The volume control lever is connected with a slider on the arm of a float which floats at the surface of the water in the tank. The slider is connected by a lost-motion connection with a closure for the discharge opening of the tank. When the water level in the tank falls to a level determined by the position of the slider on the float arm, the closure, which has been opened by operation of the flushing handle, is closed to prevent further discharge, thereby conserving water.

  • Patent number: 4080669
    Abstract: A toilet flush control is provided which is capable of dispensing different amounts of water and which comprises a rod flexibly attached to the outlet valve and loosely confined at its upper end. A floating ball slides down the rod as the water level falls and pushes the valve closed for a short flush. In a particular embodiment the ball is held at the top for full flush when the toilet seat is down and is released when the toilet seat is raised.
