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 volume control arrangement, which comprises: a flush actuator movably and detachably coupled with said valve body; and two pusher members, one of said pusher members is selected to be slidably supported at said valve body; wherein one of said pusher members is embodied as a first pusher member slidably supported at said valve body and alignedly extended towards said first position of said flushing shaft, wherein when said flush actuator is actuated to shift said first pusher member, said first pusher member is actuated to push at said first position of said flushing shaft to complete said flushing operation with a relatively high volume of water; wherein another said pusher member is embodied as a second pusher member, which is a replacement member to replace said first pusher member and to slidably support at said valve body, wherein said second pusher member is alignedly extended towards said second position of said flushing shaft, such that when said flush actuator is actuated to shift said second pusher member, said second pusher member is actuated to push at said second position of said flushing shaft to complete said flushing operation with a relatively low volume of water.
