Flushing mechanisms, for flushing a toilet bowl (22) with a reduced amount of water, each include a containment vessel (32; 200) that can fit in a standard-sized toilet cistern or tank (24) and means within the containment vessel (32; 200) for forcing water out of the vessel into the bowl (22). In a first of the flushing mechanisms (Figures 8 to 12), the containment vessel (200) includes an elastic bladder (210) which is filled with the liquid and expands to provide the additional pressure. In a second of the flushing mechanisms (Figures 1 to 7), a piston and spring system (34, 36) forces liquid out of the containment vessel (32) to flush the bowl (22). A hydraulic actuation system (60) is provided for actuating either of the flushing mechanisms. <IMAGE> |
