Abstract (en)
[origin: EP0333875A1] The water closet has a drainage port in a position higher than the floor. During a flushing operation, an air vent space is partitioned by a water wall formed by a water flux dropping from a dam and by an increase of the water level in a reservoir. The air in a trap is pushed out speedily toward the drainage port, due to the rapid flow of water to make vacuous the interior of a trap's drainage passage, and make it ready to start a siphoning action. When the feeding of water from a tank has been completed, so that the continuous siphoning action approaches the end, a notch is formed in the water wall. This notch permits the air to enter the air vent space immediately.
