  • Dual flush cistern mechanism
    Patent number: 4882793
    Abstract: The present invention discloses a dual flush cistern mechanism in which a hollow central stem functions as a flush valve operating member, a slide for a float and an overflow pipe. The float is retained on the stem by a releasable latch during normal operation. During reduced volume flush operation the latch is released, the float drops with the level of water in the cistern sliding along the raised stem until it strikes a projection thereby lowering the stem and prematurely closing the flush valve.
