Abstract

The disclosure is directed to a dynamic siphon assembly according to some embodiments. In some embodiments, the dynamic siphon assembly includes a dynamic siphon that is configured to evacuate fluid from a cistern when pushed down. In some embodiments, the dynamic siphon assembly includes a full flush actuation assembly and a partial flush actuation assembly. In some embodiments, each actuation assembly is configured to break the siphonic action of the dynamic siphon at different times and water level. In some embodiments, the dynamic siphon includes an air trap configured to trap surrounding gas such that the dynamic siphon rises during filling of the cistern. In some embodiments, the rising prevents siphonic action by raising a fluid overflow within the dynamic siphon above a fluid level in the cistern.

We claim: 
     
         1 . A dynamic siphon assembly for draining fluid from a cistern comprising:
 a dynamic siphon, and   a flush actuation assembly;   wherein the dynamic siphon comprises an air trap configured to cause the dynamic siphon to float within a cistern at least partially filled with a fluid;   wherein the flush actuation assembly is configured to push the dynamic siphon down within the cistern;   wherein the flush actuation assembly pushing the dynamic siphon down is configured to initiate a siphonic action within the dynamic siphon;   wherein the siphonic action is configured to draw the fluid through flow conduit to an exit conduit thereby reducing a fluid level within the cistern; and   wherein the dynamic siphon is configured to continue to draw the fluid until the flow conduit is exposed to a gas.   
     
     
         2 . The dynamic siphon assembly of  claim 1 ,
 further comprising a fluid trap;   wherein the fluid trap is configured to hold a volume of the fluid;   wherein the air trap is configured to be formed by trapping the gas between a fluid in the fluid trap and fluid outside the fluid trap.   
     
     
         3 . The dynamic siphon assembly of  claim 2 ,
 wherein pushing the dynamic siphon down is configured to remove the gas from the air trap.   
     
     
         4 . The dynamic siphon assembly of  claim 2 ,
 wherein the air trap is configured to trap the gas during a fluid filling of the cistern.   
     
     
         5 . The dynamic siphon assembly of  claim 1 ,
 wherein the dynamic siphon comprises a fluid overflow fluidly connected to the flow conduit;   wherein the flush actuation assembly is configured to initiate the siphonic action by moving the fluid overflow below a fluid line within the cistern.   
     
     
         6 . The dynamic siphon assembly of  claim 1 ,
 wherein the dynamic siphon is configured to be held in a lowered position by the siphonic action until the flow conduit is exposed to a gas.   
     
     
         7 . The dynamic siphon assembly of  claim 1 ,
 further comprising a static frame;   wherein the static frame is configured to guide a motion of the dynamic siphon; and   wherein the static frame is configured to be coupled to a cistern outlet.   
     
     
         8 . The dynamic siphon assembly of  claim 7 ,
 further comprising a fluid trap;   wherein the fluid trap is configured to hold a volume of the fluid;   wherein the air trap is configured to be formed by trapping the gas between a fluid in the fluid trap and a fluid outside the fluid trap.   
     
     
         9 . The dynamic siphon assembly of  claim 8 ,
 wherein the static frame comprises the fluid trap.   
     
     
         10 . The dynamic siphon assembly of  claim 1 ,
 wherein the dynamic siphon further comprises a siphon cone.   
     
     
         11 . The dynamic siphon assembly of  claim 10 ,
 wherein the siphon cone is configured to improve a flow characteristic of the fluid as it passes through the exit conduit.   
     
     
         12 . The dynamic siphon assembly of  claim 11 ,
 wherein the siphon cone is between 40 mm and 150 mm in length.   
     
     
         13 . The dynamic siphon assembly of  claim 11 ,
 wherein the flush actuation assembly comprises a full flush lever and a partial flush lever.   
     
     
         14 . The dynamic siphon assembly of  claim 13 ,
 wherein actuation of the full flush lever is configured to cause the siphonic action to last longer than an actuation of the partial flush lever.   
     
     
         15 . The dynamic siphon assembly of  claim 1 ,
 wherein the dynamic siphon is configured to automatically begin the siphonic action in response to an overfill condition within the cistern resulting in the fluid level in the cistern rising above a fluid overflow in the dynamic siphon.
