Abstract
A low water flush toilet having a bowl with a horizontal ledge extending around the bowl periphery near its open upper end with a flush water nozzle on the ledge for discharging water in a generally horizontal direction onto the ledge. A pulsator is provided for producing pulses of flush water that are discharged onto the ledge with the water of each pulse flowing at varying velocities such that as the water flows around the ledge, some of the water will fall off the ledge around substantially the entire periphery of the bowl resulting in wetting of the entire bowl surface for cleaning the bowl. The pulsator includes a spring biased piston for discharging pulses of water.
