Abstract:
A siphon flush apparatus comprising a discharge conduct extending upwardly from a bottom surface of a cistern and having a height lower than a maximum water level in the cistern; a sliding conduct having a length rising above the maximum water level in the cistern when a bottom of said sliding conduct is at a top of the discharge conduct, the sliding conduct being concentric to the discharge conduct and having a sectional area large enough to house said discharge conduct; a flow directing element for initiating and maintaining a siphon by directing water flow towards a top of the sliding conduct, sealing means engaged between the bottom of the sliding conduct and a top of the discharge conduct for providing a seal between the discharge and sliding conducts and operatively joining each other; fastening means fix to the top of sliding conduct for separably engaging the sliding conduct to the flow directing element and for providing a space between the top of the sliding conduct and the flow directing element for allowing water flow; floating means for moving said flow directing element upwards along with the sliding conduct; first stopping means for preventing the sliding conduct from moving upwardly beyond the discharge conduct; and, second stopping means to prevent the sliding conduct from reaching a bottom of the sealing means when the sliding conduct moves downwards.
