Abstract
A flush valve has a valve body having a flushing tube, a power generating set, and a solenoid valve assembly. The power generating set is disposed within the flushing tube and has a turbine capable of rotating, an induction coil, and a magnet inserted through the induction coil and capable of simultaneously rotating with the water turbine. The solenoid valve assembly has an assembling mount, a solenoid valve assembled to the assembling mount, and a power supply electrically connected to both the induction coil and the solenoid valve. A first reserving space is formed between the assembling mount and a relief assembly. A second reserving space is formed between the solenoid valve and the assembling mount and communicates with the first reserving space. The solenoid valve optionally prevents the first reserving space and the second reserving space from communicating with each other.
