Semi-flush flapper valve

A semi-flush flapper valve apparatus for use in a toilet of the type having a tank, a flush port, a valve seat and an overflow tube, said apparatus comprising:

• a) an operating handle rotatively mounted to the toilet tank, so that the operating handle can rotate both in a first direction and in a second direction;
• b) a main flapper valve having a bottom chamber for trapping air therein and a top air release hole, said main flapper valve is pivotally mounted at one end to the overflow tube, so as to normally sit upon the valve seat over the flush port with said bottom chamber communicating with said flush port;
• c) a bleeder valve which is pivotally mounted at one end onto said main flapper valve to normally cover the top air release hole;
• d) a first means, coupled between said operating handle and said main flapper valve, for causing a conventional full flush cycle in the toilet tank, when said operating handle is rotated in a first direction on the toilet tank, so as to pivot said main flapper valve about said one end while said bleeder valve remains closed over said air release hole;
• e) a second means, coupled between said operating handle and another end of said bleeder valve, for causing a semi-flush cycle in the toilet tank, when said operating handle is rotated in a second direction on the toilet tank, whereby said bleeder valve will pivot about said pivotal mounting to open said air bleeder hole and pull up said main flapper valve, allowing said main flapper valve to subsequently close faster than normal onto the valve seat due to lack of buoyancy thereof.
