Patent ID: 8596606

Claim:
An automate fluid flow control system for a fluid system having a fluid inlet, a fluid outlet, and a fluid chamber communicating between said fluid inlet and said fluid outlet, wherein said automate fluid flow control system comprises: a relief valve adapted for being sealedly disposed within said fluid chamber for sealing a flow of fluid flowing from said fluid inlet to said fluid outlet, wherein said relief valve has a fluid passage defining a passage opening with a diameter smaller than a diameter of said fluid chamber for controlling a flow rate of fluid passing from said fluid chamber to said fluid outlet, and comprises a valve stopper sitting on said passage opening of said fluid passage to sealedly close said fluid passage for controlling said fluid flowing from said fluid chamber to said fluid outlet; a power generator, wherein said valve stopper is moved between a closed position and an opened position through an actuation of said power generator; and an actuator operatively driven by said power generator, wherein said actuator comprises a driving arm movably extended from said power generator towards said fluid passage and a pusher arm non-coaxially extended from said driving arm to said valve stopper such that when said driving arm is driven to be moved by said power generator, said pusher arm is driven to correspondingly move to move said valve stopper from said closed position to said opened position, wherein at said closed position of said valve stopper, said valve stopper is sealedly retained to close said fluid passage for blocking said fluid passing to said fluid outlet, and at said opened position of said valve stopper, said actuator drives said valve stopper to unseal said fluid passage for allowing said fluid passing to said fluid outlet through said fluid passage; wherein said valve stopper has an engaging surface arranged in such a manner that when said actuator is moved, said actuator pushes at said engaging surface of said valve stopper to move said valve stopper from said closed position to said opened position; wherein said relief valve further comprises a resilient element, which is disposed within said fluid passage, having a biasing end coupling with said valve stopper and an opposed affixing end coupled with a bottom opening end of said fluid passage for applying an urging force against said valve stopper so as to retain said valve stopper at said closed position.
