Document Type and Number:
Japanese Patent JP4562879
Kind Code:
B2
Abstract:
A diaphragm type flush valve for use with toilet devices such as urinals and water closets includes a body having an inlet and an outlet, a valve seat between the inlet and outlet, and a valve movable to a closing position on the valve seat to stop the flow between the inlet and outlet. The valve member includes a diaphragm peripherally attached to the body and a disc positioned on top of the diaphragm. There is a guide extending downwardly from the diaphragm. The disc is attached to the guide and functions to secure the diaphragm, disc and guide into the valve member. The disc includes a rigid body and a seal member, with the seal member having a portion on an upper surface of the disc for sealing contact with a relief valve, and a portion on a lower surface of the disc for contact with the diaphragm. The disc is attached to the guide through a one-way clutch which permits relative rotation of the disc and guide in one direction during assembly, and prevents relative rotation in the opposite direction after assembly.
