Abstract:
1. A flush system, comprising: a valve body having a water inlet and a water outlet; a valve seat supported in said valve body between said water inlet and said water outlet, wherein said valve seat is adapted to move between a normal idle position that water is blocked to flow from said water inlet to said water outlet and a flushing position that said water is allowed to flow from said water inlet to said water outlet so as to complete a flushing operation; a flushing shaft extended from said valve seat to move said valve seat between said idle position and said flushing position, wherein said flushing shaft defines a first position and a second position; and a flush water control arrangement, which comprises: a flush actuator movably coupled with said valve body; and a water control pusher comprising a low volume pusher member and a high volume pusher member alignedly extended towards said first position and said second position of said flushing shaft respectively, wherein said flush actuator is selectively actuated one of said low volume pusher member and said high volume pusher member to complete said flushing operation, wherein said high volume pusher member is actuated to push at said second position of said flushing shaft to complete said flushing operation with a relatively high volume of water, wherein said low volume pusher member is actuated to push at said first position of said flushing shaft to complete said flushing operation with a relatively low volume of water.
