    摘要： A combination of a toilet and an anti refill device, the toilet comprises a bowl, a tank connected to the bowl for storing water and to supply the stored water to the bowl, a flushing structure which releases water from the tank into the bowl, a supply valve for refilling the tank with water after the flushing structure has released all the water into the bowl and a float structure for activating and deactivating the supply valve by floating in the water so that when the water is low the supply valve is activated and when the water is full the supply valve is deactivated. The anti refill device comprises a lock arm attached to the float structure and has an end, a lock device arranged to cooperate with end for controlling the lock arm and a structure activated by the flush structure which activates the lock device and the end to release the lock arm so the float arm lowers and the supply valve can fill the tank after flushing. The device is arranged to stop the float structure from activating the supply valve when the flushing structure is not activated. The lock arm is held in place by the lock device and the end such that the float structure does not activate the supply valve, wherein the end and the lock device engage to define a ratchet in which a plurality of teeth have a first side so that the lock arm slides against the lock device so that the float arm can activate the supply valve and a second side of the teeth being at an angle such that the float arm is prevented from lowering.

    摘要： A non-chattering, float-controlled, pilot-operated diaphragm valve for controlling the flow of liquids from a conduit under pressure to a tank where the surface is in turbulent condition. The lightweight float and pilot valve follow the relatively high frequency fluctuations of level and the diaphragm valve responds causing a rapid opening and closing of the main flow through the conduit into the tank. The chattering is eliminated by the insertion of operative means between the float closure means and the movable diaphragm. A small diameter rod of selected length is positioned between the diaphragm and the closure means so that when the main flow through the conduit starts, the movement of the diaphragm away from the conduit forces the pilot valve to open and submerge the float to a considerable depth. While the float rises, the pilot valve remains open permitting the main flow to continue, and raising the level in the tank a substantial amount so that there is a continuing pressure on the float to maintain a closed pilot. This prevent the immediate reopening of the conduit and therefore, removes the rapid chattering action.

    摘要翻译： 一种无颤动的浮动控制的先导式隔膜阀，用于控制液体从压力下的管道流向表面处于湍流状态的罐体。 轻便的浮动和先导阀跟随水平相对较高的频率波动，隔膜阀响应，导致通过导管进入油箱的主流的快速打开和关闭。 通过在浮动闭合装置和可移动隔膜之间插入操作装置来消除颤动。 选定长度的小直径杆位于隔膜和闭合装置之间，使得当通过导管的主流动开始时，隔膜离开导管的运动迫使先导阀打开并将浮子淹没到相当大的深度 。 当浮子上升时，先导阀保持打开，允许主流继续运行，并且将罐中的液位提高到相当大的量，使得浮子上持续压力以维持封闭的引导。 这样可以立即重新打开导管，因此可以消除快速颤动的动作。
