Self closing mixing cartridge for single handle cartridge type faucet |
摘要 |
A self closing cartridge for a single handle faucet includes a casing having a piston therein which is held in a normally closed, up position by water pressure. There are seal members positioned to form a seal between the sleeve and the casing. Further, a spring is incorporated to assist the hydraulic self closure of the cartridge by raising the piston to a normally closed position under low water pressure conditions and to mechanically shear and digest any deposited matter in the area of the spring.
