Abstract

A vacuum assisted toilet is described in which a vacuum is applied between upper and lower traps (40, 44 in fig.2) of a toilet bowl outlet during a flushing, in which the lower trap is constructed to more reliably assure that an air passage (64) above a pool of water (52) of the lower trap will quickly close near the beginning of a flushing and will remain open between flushings. The lower trap has a lower wall (51) that holds a pool of water (52) with a pool top (62) of predetermined height (A) between flushings, and has an upper wall (60) spaced above the pool top to form an air passage. The upper wall forms a narrow but tall vent (100, fig.4) of the air passage that is open between flushings, with the vent being quickly closed by water rapidly flowing therethrough at the beginning of a flushing and being quickly opened at the end of the flushing.
