The present invention provides a leakage proof, water saving flushing device for effectively managing water resources through an interlocking mechanical assembly. The said interlocking mechanical assembly is made up from a water channel gate arm having a distal end and a gate end, and a floating air pocket arm having a floating air pocket end and a distal end. Wherein, the distal end of the said floating air pocket arm is placed perpendicularly against the said distal end of the said water channel gate arm and provides an interlocking mechanism. The said interlocking mechanical assembly also comprises an operating element adapted for providing a push force to an elongated connecting arm, wherein the said elongated connecting arm provides a push force to unlock the said interlocking mechanical assembly.

Disclosed herein is actuation apparatus. The actuation apparatus comprises a diaphragm valve, having an upstream side and a downstream side, opposite the upstream side. The actuation apparatus also comprises a hydraulic actuator, fluidically coupled with the downstream side of the diaphragm valve by a first hydraulic line. The actuation apparatus further comprises a valve fluidically coupled with the upstream side of the diaphragm valve by a second hydraulic line. The actuation apparatus additionally comprises a valve controller coupled with the valve and operable to open and close the valve. Pressurized fluid from the downstream side of the diaphragm valve flows to the hydraulic actuator, via the first hydraulic line, in response to opening of the valve. The hydraulic actuator is configured to actuate in response to receipt of pressurized fluid from the downstream side of the diaphragm valve.

Flush valve assemblies are described herein which include a valve body; a flush valve cover detachably connected to a flush line; a pivot mechanism capable of opening and closing the flush valve cover upon actuation; wherein the flush line is connected at a first end to a flush actuating device and at a second end to the flush valve cover, the line being capable of raising and lowering the cover upon actuation; and a float situated above the cover and connected to the flush line at a point between the first and the second ends of the flush line or by a separate float line connected to the cover. The float is sufficiently buoyant and capable of resisting the force of flowing water and keeping the flush valve cover open to allow flush water to pass through the valve body before closing the cover when the valve body is installed on a 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 flush actuator assembly for a plumbing fixture includes a housing, a handle and a lever. The housing is configured to be removably coupled to the plumbing fixture. The handle is pivotally and removably coupled to the housing. The handle includes a stem configured to extend through the plumbing fixture and into the housing. The arm is removably coupled to the stem within the housing. The arm is configured to pivot with the handle. The lever is at least partially disposed in the housing, and is configured to be selectively disengaged from the stem to removably couple the handle to the housing.

A discharge valve operating device includes an electric operation unit including a rotating shaft, a first coupling member and a second coupling member having respective one ends coupled to a discharge valve, a first rotary winding member, and a second rotary winding member. The first rotary winding member and the second rotary winding member include a first holed portion and a second holed portion, respectively, which are provided near portions at respective rotation centers. Each holed portion is engageable and disengageable with the rotating shaft in a rotation direction in accordance with the rotation direction of the rotating shaft in each operation mode.

A rigid piston assembly for use in a conventional flush valve includes a rigid piston and a solenoid configured to fixedly engage within the valve body. A flush valve for a plumbing fixture as well as a method of retrofitting a piston valve into a diaphragm flush valve body which includes a rigid piston and solenoid configuration.
