    Abstract: A dual mode flush valve includes a handle assembly having a handle, a bushing and a plunger. The bushing has a sleeve with a passage therethrough for mounting the plunger for sliding and tilting. The passage is defined by first and second partially overlapping bores that coincide at the inner end of the sleeve and are spaced one above the other at the outer end of the sleeve. The bores define a horizontal plunger travel axis and an angled plunger travel axis. Depending on which direction the user actuates the handle the plunger will travel along one of these axes. Travel along the angled axis will lower the plunger tip, allowing earlier clearance of a relief valve and a reduced flow through the flush valve compared to actuation with the plunger travel along the horizontal axis.

    Abstract: A water conservation device for use within a toilet is disclosed. In at least one embodiment, the device includes a connector having a base adapted for connectivity and placement adjacent to a traditional pole assembly and proximate to an opening valve within a tank of the toilet. In at least one embodiment, the device includes a flexible pressure arm integrally formed with the connector base and adapted to couple to the opening valve within the tank of the toilet and adapted to provide a pressure to the opening valve to lessen overall water utilized in each flush of the toilet and thereby conserve water. The water conservation device is adapted for either a total or partial flush of the toilet as selected by a user.

  • Patent number: 8584268
    Abstract: A dual flush device is disclosed to provide a full flush for removing solid waste and a water-saving partial flush for removing liquid or light solid waste in a toilet. It includes a first flush handle attached to a shaft to raise a lever to open a flapper valve, and a second flush handle that overlaps the first handle and opens the flapper valve through the first handle. A float assembly is disclosed to be used either with the dual flush device or with the original single flush lever assembly to prematurely close an opened flapper valve and reduce water consumption. Using the original flapper valve in a conventional toilet tank, a dual flush function is achieved by any of the three implementation choices: (1) the dual flush device alone; (2) the dual flush device and a float assembly; and (3) a float assembly alone.

  • Patent number: 8561225
    Abstract: A multi flush volume flush valve is in communication with an automatic flush control. The flush control determines the presence of a user and the amount of time the user uses the toilet. The usage time is compared to a predetermined time value to determine the appropriate flush volume based on an assumption regarding usage time and flush volume needs. The comparative value statistically adjusts to the restroom traffic.

  • Publication number: 20130232677
    Abstract: A control system for a flush toilet includes a water delivery device for delivering a source of flush water to a bowl. The control system includes a controller and a user interface. The controller is operative to control the toilet through a flush sequence in a first mode and a second mode. In the first mode, the controller opens the water delivery device to deliver a predetermined amount of water to the bowl. In the second mode, the controller opens the water delivery device to deliver a user adjustable amount of water to the bowl. The user interface is in communication with the controller for selecting between the first mode and the second mode. Where the toilet is a macerator toilet, the controller monitors current draw unit when the current draw satisfies a predetermined current condition. The controller may operate in a normal mode and a lockout mode.

  • Patent number: 8528876
    Abstract: An apparatus for providing flushing fluid at different rates has a valve for controlling flow through a housing, the valve having a reset area to close the valve, a first bleed valve for constantly providing high pressure fluid to the reset area through a first path, a second bleed valve for providing high pressure fluid to the reset area through a second path, and an actuator. The actuator has a first position in which fluid is prevented from escaping from the second path, a second position in which fluid is allowed to escape from the second path and the second bleed valve is activated, and a third position in which fluid is allowed to escape from the second path and the second bleed valve is deactivated.

  • Publication number: 20130219606
    Abstract: An actuation mechanism comprising a first handle, a second handle, a housing, a link arm member provided within the housing and pivotally coupled to the handles, and a moveable stop member provided within the housing. The first handle may be mounted to a first side of a toilet tank, and the second handle may be mounted coaxially relative to the first handle on the first side. The housing may be mounted to a second side of the tank. A rotation of one of the first and second handles results in rotation of the link arm member being limited by the moveable stop member such that the link arm member is permitted to rotate a first amount. Rotation of both the first and second handles results in movement of the moveable stop member such that the link arm member is permitted to rotate a second amount greater than the first amount.
