ABSTRACT:
An automatic lift faucet includes a hydraulic cylinder vertically mounted under a working top, the hydraulic cylinder having an inlet. A lifting faucet is mounted in motion fitting connection within the hydraulic cylinder and includes an inlet and a faucet outlet. A lifting piston is attached to the lifting faucet for controlling fluid communication between the hydraulic cylinder and the lifting faucet inlet. An accumulator cylinder is mounted to the bottom end of the lifting faucet and includes a baffle-plate, a valve stern and left and right tow pistons to thereby divide the accumulator cylinder into three sub-chambers. The accumulator cylinder also includes three through-holes, one of each communicating with one of each of the three sub-chambers. A pressure release valve selectively controls fluid communication to the through-holes and to the hydraulic cylinder inlet via first and second branch pipes.
