Abstract
A flush valve diaphragm that includes a body portion and a peripheral sealing portion. The body portion is flexible and has a central passageway. The peripheral portion includes an integral filter, an exit chamber, and a bypass arrangement, such that water flowing through the filter flows through the bypass arrangement. The integral filter prevents clogging of the bypass arrangement. The diaphragm is used in a flush valve diaphragm assembly and a flush valve.
