Toilet Flush Valve With Reducing Cross Section Valve Seat |
摘要 |
A canister flush valve is disclosed with a valve seat modified to accommodate a greater initial surge of flow, without distorting flushing performance. There is a mounting at the bottom of a toilet tank that links to an outlet hole from the tank and forms a valve seat. A passageway through the mounting tapers in an arcuate manner below the valve seat. There is also a guide support structure in the passageway, preferably centered. The guide support structure also has a tapered leg.
