A refill ring for use in a diaphragm-type flush valve is mounted upon the guide member of the diaphragm assembly. The refill ring has an outer diameter approximating the inner diameter of the flush valve passage adjacent the diaphragm seat. The refill ring has a plurality of recesses formed about its periphery whereby closure of the diaphragm assembly upon its flush valve seat moves the refill ring within the flush valve passage, the exterior of the refill ring being in contact with the interior of the passage such that the flow of water past the refill ring is limited to the area of the refill ring peripheral recesses.

Cette invention concerne un anneau de remplissage pour robinet de chasse à membrane monté sur l'élément de guidage de la membrane. L'anneau de remplissage a un diamètre extérieur correspondant à peu près au diamètre du passage intérieur du robinet à la hauteur du siège de membrane. Il comporte une série de creux périphériques qui font en sorte que, lorsque la membrane est appliquée sur son siège, il se place à l'intérieur du passage intérieur du robinet, son pourtour étant en contact avec la paroi dudit passage intérieur, et la quantité d'eau s'écoulant à sa périphérie est limitée à ce qui passe par les creux non en contact avec ladite paroi dudit passage intérieur.
