A gear driven trip lever for a toilet comprises a handle, a handle stop and a torsion spring disposed outside the tank. Inside the tank is a gear driven trip lever subassembly comprising a home position rack that is secured to a mounting plate and a spring-loaded clutch cam. The end of the flush lever nearest the gear driven trip lever subassembly is configured as a geared structure that meshes with gears disposed on a home position rack. When a user pushes the flush handle, the home position rack lifts the geared flush lever. The clutch cam contacts and slides on the home position rack as it moves downwardly. When the flush handle is fully depressed downwardly, the clutch cam releases the home position rack which returns to its home position via a compression spring and the geared flush lever is returned to its home position.

An assembly comprises an outer subassembly, a toilet tank, and an inner subassembly. The outer subassembly further comprises a handle, a handle stop, a torsion spring disposed between the handle and the handle stop, and a tank hole seal. The inner subassembly further comprises a mounting plate to receive the outer subassembly. A drive pin is coupled to the mounting plate. The inner subassembly further comprises a flush lever and a roller subassembly.

A flush valve assembly, comprising a flush valve comprising a flush valve body extending from a flush valve inlet to a flush valve outlet; a flapper cover having a top face and a bottom face and a front and a back; and a flush actuator comprising a lift rod; wherein the bottom face of the flapper cover is configured to enclose the flush valve inlet; and wherein the lift rod is coupled to the top face of the flapper cover and is configured to lift the flapper cover to partially open the flush valve and to fully open the flush valve.

A flush assembly for a toilet with a tank can include a rigid siphon body with a siphon inlet, a siphon outlet, and a siphon passage. An outlet assembly can be coupled to the siphon outlet to provide a liquid flow path between the siphon outlet and a flush port of the tank. The rigid siphon body can be configured to float within the tank and to be submerged to establish a siphon-driven flow of liquid from the tank to the flush port to flush the toilet.

The present invention relates to a toilet flushing device using a toilet cover. More specifically, the present invention comprises: a sliding means disposed at the front side of a water tank and configured to slide forward/backward by magnetic force to allow a drain valve to operate as soon as a toilet cover is closed; and an operation lever disposed at the rear side of the sliding means so as to open or close the drain valve, wherein the drain valve is operated to flush water by a structure in which the sliding means and the operation lever operate in cooperation in response to an operation of the toilet cover after use of the toilet. Therefore, the present invention can induce the habit of covering the toilet by the toilet cover after using the toilet and thus enhance a sanitary culture.

A fill valve system with a float nested in a container connected to the fill valve and a siphon device passing water out of the container into the toilet tank, with the siphon device having an air vent dimensioned such that: (i) tank refilling is delayed until after the flush valve closes; (ii) the fill valve is not turned on by small leaks in the tank; and (iii) the fill valve turns off when it encounters large leaks in the tank.
