Abstract
A siphon flush apparatus is described which by means of a sliding conduct coupled to a discharge conduct allows the formation of a siphon during the flush operation of a cistern without the need of a jet stream of water, valve means or a piston to initiate said siphon. In addition, the apparatus of the present invention can remain without any leakage into the flushing tube when it is at rest position and need not an additional overflowing discharging pipe to drain an excess of water when the supply valve of the cistern fails.
Claims20
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.
