Abstract

See full text

A multi-stage toilet flush valve includes an inner valve and an outer valve that circumstribes the inner valve. The inner and outer valve control the flow of flushwater through associated inner and outer outlets. Thus, when the flush valve is actuated, the inner and outer valves are actuated at separate times, while the inner valve delivers flushwater to a rim of the toilet, while the outer valve delivers flushwater to a jet feed outlet in the toilet. As such the multi-stage toilet valve provides two independent inner and outer flushwater delivery outlets that are controlled by associated inner and outer valves that are capable of being actuated at separate times to control the ratio of flushwater delivered to a toilet rim and to a toilet jet feed outlet to enhance the effectiveness in which the toilet bowl is cleaned.
