Patent ID: 8714516

Claim:
A non-adjustable water pressure and flow speed regulating flush system having a water inlet and a water outlet, comprising: a valve member adapted for sealedly disposing between said water inlet and said water outlet to define a water chamber, wherein said valve member comprises: a valve seat which comprises a sealing platform and a valve barrel downwardly extended from said sealing platform toward said water outlet for communicating said water chamber with said water outlet; and a sealing diaphragm sealed at said water chamber, wherein said sealing diaphragm has a center immovable portion affixed at said sealing platform to restrict said center immovable portion to be moved by its flexibility and an outer peripheral movable portion sealed at and sat within said water chamber, such that said outer peripheral movable portion is adapted to be moved by its flexibility; a relief valve disposed within said water chamber of said valve member for controlling said water flowing from said water chamber to said water outlet, wherein said relief valve comprises a sealing seat sitting on said sealing platform, a valve controlling shaft coaxially extended from said sealing seat to coaxially encircle within said valve barrel, and a valve stopper movably sat at said sealing seat; and a flow speed regulation arrangement which comprises an elongated bleed channel coupling with said center immovable portion of said sealing diaphragm, wherein said bleed channel, which is a curved channel, has a first opening extended through said center immovable portion of said sealing diaphragm for communicating with said water inlet and a second opening extended through said sealing platform for communicating with said water chamber to control a water pressure between said water inlet and said water chamber in a non-adjustable manner, so as to regulate a flow speed of said water entering into said water chamber through said bleed channel, wherein said bleed channel comprises an elongated water conduit having a predetermined length between said first and second openings and extending through said center immovable portion of said sealing diaphragm to communicate between said water inlet and said water chamber for balancing said water pressure therebetween.
