ABSTRACT:
A dual flush valve that can be operated in a partial flush mode to release only about half of the tank water to the toilet bowl, or in a full flush mode to release almost all of the tank water, is of simple and reliable construction. For a partial flushing a chain device (64, FIG. 2) connected to the outer end of the flush member, is pulled to raise the flush member only a small amount (to 14C), and a release mechanism (90) is connected to a separate location on the flush member to keep it up until a float (110) senses that about half of the tank water has been released. The float pivots an arm (102) to disengage a latch 94 on the arm from a catch (96) on the yoke of the flush member to release it. The float slides along the refill/overflow tube (26).
