Abstract
The suction-type siphon has a channel which runs from an inlet opening to an outlet opening and has a bend for receiving sealing water. After the said bend, as seen in the direction of flow, the channel has a depression causing the formation of a sump which constricts the channel for the passage of air. The constriction by means of the sump makes filling possible with little water, but does not impede the passage of solid objects. A urinal having the suction-type siphon according to the invention can be flushed with little flushing water, for example, less than one liter of water.
