Abstract

See full text

A flush toilet system includes a bowl that is drained in a flush operation through a flow path including a trap and a siphon. A bypass passage supplies a back jet of water in the reverse flow direction in the flow path. A back jet valve assembly opens to permit back jet flow during only the first part of the interval during which flush water is supplied to the system from a water supply. The kinetic energy of the back jet is converted to static pressure to block or impede flow of flush water through the flow path. Water level increases in the bowl, and when the back jet flow is discontinued a siphon flush operation proceeds. The back flush valve assembly also releases water after the flushing operation in order to reseal the trap.
