  • Filter device for flush valves
    Patent number: 6722384
    Abstract: A filter device and method for diaphragm type flush valves includes positioning the filter device in a cavity of the valve, between an inlet and an outlet pipe, and between an inlet and a bleed hole of a diaphragm of the valve. The filter device spans the entire span between an outlet pipe and a valve wall. Thus, all water entering the valve through the inlet passes through the filter prior to exiting through the outlet pipe, or prior to passing through the bleed hole in the diaphragm. The filter device can have a tubular or frusto-conical shape with a first, lower opening sealing about the outlet pipe, and a second, upper opening sealing against the valve wall.
