A combined flushing and filling unit comprising a flush valve and a filling valve, which are situated in an inlet chamber to which line pressure is to be applied, and, between the inlet chamber and a particular outlet line, form a compensation chamber, each of which is closed with the aid of a servo-diaphragm, wherein the inlet chamber communicates with the compensation chambers via a connection opening, in each case, in the servo-diaphragm, and the compensation chambers each have a control opening for generating a pressure decrease, which releases the particular outlet line, in the relevant compensation chamber. Furthermore, a method for the operation of a combined flushing and filling unit comprising a flush valve for triggering an emptying process of a cistern is disclosed.

There are provided a flush water tank apparatus capable of accurately setting the amount of flush water to be discharged while opening a discharge valve by a discharge valve hydraulic drive unit. A flush water tank apparatus includes a valve controller, where, in a case where a first amount of flush water is selected, the valve controller causes the timing control mechanism to be engaged with the discharge valve and causes the timing control mechanism to operate such that engagement is released after a lapse of a first period of time, and in a case where a second amount of flush water is selected, the valve controller causes the timing control mechanism to be engaged with the discharge valve and causes the timing control mechanism to operate such that engagement is released after lapse of a second period of time shorter than the first period of time.

The present invention is a flush water tank apparatus (4) and includes: a storage tank (10) on which a drain port (10a) is formed, a discharge valve (12) opening/closing the drain port; a discharge valve hydraulic drive unit (14) driving the discharge valve using water supply pressure; a clutch mechanism (30) coupling the discharge valve and the discharge valve hydraulic drive unit to pull up the discharge valve; flush water amount selection device capable of selecting between a first and a second amount of flush water; a timing control mechanism controlling a timing of the drain port being blocked; and a control jet unit (20) jetting, when the second amount is selected, flush water to a water receiving surface provided on the timing control mechanism so that a timing of the drain port being blocked is earlier than a case of the first amount of flush water.

A flush water tank apparatus enabling accurately setting an amount of flush water to be discharged while opening a discharge valve via a discharge valve hydraulic drive unit and a flush toilet apparatus including the flush water tank are provided. A flush water tank apparatus includes a first float device; a second float device that prevents from descent of the discharge valve according to the water level so as to discharge a second amount of flush water; and an adjustment mechanism configured so that when the second amount of flush water is selected by the flush water amount selection portion the clutch mechanism is disconnected at a pull-up height of the discharge valve such that the discharge valve descended by the disconnection of the clutch mechanism is held by the second float device in a holding state.

A toilet has a porcelain body including a tank that defines a first fluid passageway, a bowl integral with the tank and connected with a second fluid passageway that intersects the first fluid passageway, the second fluid passageway is integral with the tank and the bowl, and an outlet located downstream of the intersection of the first fluid passageway and the second fluid passageway, and the outlet includes a seat. The toilet includes a flush mechanism inside the porcelain body and has a weighted stopper configured to contact the seat of the outlet, a flexible connecting element having a first end connected to the stopper, a float connected to a second end of the flexible connecting element, a pull chain having a first end connected to the float, and a rocker arm rotatably connected to the body and connected to a second end of the pull chain.

A toilet that includes a tank configured to hold water from a water supply; a reservoir fluidly connected to the tank and configured to hold a cleaning compound comprising a chemical compound and water from the water supply; and an actuator configured to control a flush cycle of the toilet upon a first activation, the actuator including at least one nozzle fluidly connected to the reservoir and configured to discharge an amount of the cleaning compound external to the tank upon at least one of the first activation or a second activation.
