Abstract
A flush valve assembly of the present invention includes a body subassembly in operable communication with a movable poppet seal subassembly via a guide rod of a predetermined length. The body subassembly inlet is substantially located above the tank floor, thereby reducing available tank discharge volume. The poppet subassembly includes a float having upper and lower float covers with an annular seal disposed therebetween. The poppet subassembly remains coaxially and slidably mounted with respect to the body subassembly so as to create a valve opening therebetween when the poppet subassembly is removed from its initial closed position to a second open position. Guide structure in the body subassembly accommodates reciprocatable movement of the guide rod and inhibits deviation of the guide rod from a predetermined axial guide path when the poppet subassembly is in use during a flush cycle. An optional valve bracket may be provided.
