Accelerated rim wash for a toilet

摘要

A fill valve (36) has a main valve (34) with a control chamber (44) for controlling the on and off actuation of the main valve. A tube (58) is in fluid communication with chamber (44) and extends into the water at the fill level (46) in tank (10). The flush valve (64) is connected to tube (58) such that upon actuation it raises tube (58) and lowers the pressure in chamber (44) to turn on the main valve (34) independent of whether the water level in tank (10) drops below its fill level (46) to direct water from the main valve to a rim wash conduit (28).
