Patent ID: 7857280

Claim:
An automatic actuation apparatus for a valve body having a water inlet and a water outlet, comprising: a valve member adapted for sealedly disposed between said water inlet and said water outlet to control water flowing from said water inlet to said water outlet; and a powering assembly, comprising: a power generator, a relief valve having a water passage extended along said valve member for communicating with said water outlet, and comprising a valve stopper disposed at an opening of said water passage to close said water passage, and a resilient element applying an urging force against said valve stopper to normally retain said valve stopper on said opening of said water passage; an actuator driven to be rotated by said power generator to move said relief valve between an auto-operated closed position and an auto-operated opened position, wherein at said auto-operated closed position, said valve stopper is sealedly retained at said valve stopper to close said water passage for blocking said water passing to said water outlet, and at said auto-operated opened position, said actuator is driven by said power generator to move said valve stopper away from said opening of said water passage for allowing said water passing to said water outlet; and a CPU operatively activating said power generator for controlling a time of a flushing cycle, wherein said CPU controllably activates said power generator to control a speed of said actuator so as to control the time of said flushing cycle.
