摘要： A flush consistency control system may comprise a reservoir with a drain opening for egress of liquids from the reservoir into a toilet tank. The reservoir may comprise a surface with one or more walls and a partition on the surface dividing the reservoir into multiple compartments which may house liquids, wherein the compartments are in fluid communication through a gap so liquids flow at a predetermined rate between the compartments and through a drain opening of the reservoir. A flush consistency control system may also comprise a post with one or more latches extending away from the post, the latch having a lower mounting surface which extends away from the post at a declining angle and a latch-strike end of a float lever that securely engages with the lower mounting surface of the latch when the float descends.

摘要： A dual flush button assembly includes a unitary button with a full flush surface and a partial flush surface. Pressing the partial flush surface moves the button linearly to active a partial flush. Pressing the full flush surface rotates the button to activate a full flush. An extension member beneath the button is coupled to a link of a dual flush valve. The extension member is moved farther when the full flush surface is engaged. The button is configured to pivot with respect to a housing when the full flush portion is engaged.

摘要： A flush valve apparatus for a toilet tank includes a float that provides a buoyancy force to a flush valve flapper. The float may be coupled to a chain connecting a lever and the flapper, or directly to the flapper. The float may be selected from a set of floats having a variety of sizes and shapes. Once a selected float is installed, the position of the float is fixed relative to the valve flapper, thus preventing change in the amount of water consumption per flush, which depends upon the buoyancy force on the flapper. For different standards, floats of different shapes and/or sizes may be selected such that the amount of water consumption per flush meets the standards.

摘要： Embodiments of the invention provide a gasket for a fluidic seal. Some embodiments include a flush valve to a toilet tank, where the gasket has a raised center portion and lowered inner and outer portions. In some embodiments, the gasket includes a plurality of recesses, troughs or grooves. Each of the three portions of the gasket has a bottom groove that can permit deformation and increases sealing capabilities when the groove either widens or narrows. Additionally, some embodiments include an inner support ring that extends inwardly from the lowered inner portion, and can center the gasket onto the flush valve.
