Abstract: A manual water-feeding mechanism for a sensor faucet includes: a base connected to at least one water inlet; a solenoid seat connected to a water outlet of a water pipe directed to the faucet; a base containing therein a first channel communicated to a water inlet and a second channel in the solenoid seat, wherein a solenoid diaphragm controls open and close of the second channel; a third channel, communicated to the first channel from its lateral side; a fourth channel having one end connected to third channel and an opposite end connected to second channel behind the solenoid diaphragm; and a manual stem having one end abutting between a middle section and an exit of the third channel. The manual stem when rotated allows water to flow through the third channel, the fourth channel and the second channel to the water pipe.

Abstract: A controller assembly for an automatic flush valve provides economical approach to transforming a manual flush valve into an automatic flush valve. The controller assembly includes a base for holding a battery set and a sensor into a combination, and a cap covering the combination. A solenoid valve and a membrane below the combination are receiving in a socket of a foundation. A ring is rotatably mounted around a bottom of the foundation. A sleeve passing the cap is mounted around the foundation and stands on the ring. The ring allows the controller assembly to be easily assembled with a valve body of any type into an automatic flush valve or to be easily removed from the automatic flush valve and replaced by a manual controller assembly so as to form a manual flush valve. Thereby, the transformation can be economical accomplished without replacing the existing valve body.
