Abstract:
An improved water faucet control cartridge comprising;a rotary control stem that is situated at the center of a cartridge body and installed below the handle of a water faucet;a sealing disk that is fitted to the bottom end of the rotary control stem and for rotating synchronously with the rotary control stem;a flow guide disk that is positioned under the sealing disk and has an outer circumference that fits into a water output seat of the water faucet;an eccentrically arranged valve for varying the water flow path assembled to the bottom end of the said flow guide disk, said valve having a flat, substantially semicircular, top surface for sealing against a portion of a bottom surface of the flow guide disk;the eccentrically arranged valve having a plastic construction an internal offset flow passage, wherein an upper extent of the said offset flow passage is contiguous with a flow guide hole in the flow guide disk and a lower extent of the offset flow passage is continuous with a washer in the faucet water supply pipe seat; andwhereby when the user rotates the handle, the rotary control stem is driven into rotation along with the sealing disk causing the water outlet hole and the water outlet edge of the sealing disk at the bottom end of the cartridge body to become aligned and also causing the alignment of the water outlet edge of the sealing disk with the flow guide hole, thereby allowing water to flow from the output opening of the water supply pipe seat through the eccentrically arranged valve and the sealing disk, after which the water flows through and emerges from the water outlet hole of the cartridge body.
