ABSTRACT:
A flushing cistern includes a flushing device which is located in a liquid-containing cistern. The device includes a hollow tube and a closure member carried by the tube. The tube can be moved in the cistern between open and closed positions in which the closure member is clear of, and seals the cistern outlet. A float is mounted on the tube to hold the tube in the open position while flushing takes place and which causes the tube to resume its closed position at the end of the flush. The device also includes a float arm carrying a float. The float arm is pivoted to a control arm of the inlet valve to the cistern, and there is a detent on the tube which engages the float arm and pulls it downwardly when the flush is over, so operating the control arm and opening the inlet valve to admit further liquid to the cistern. When the cistern has again filled up, the float arm detaches itself from the detent, and permits the inlet valve to close again.
