Abstract: A flush toilet comprises a toilet body, a water supply pipe connected to supply wash water, a discharge port connected to discharge wash water, a valve disposed between the water supply pipe and the discharge port, a valve switching device connected to switch the valve, a spring operably connected to drive the valve switching device, a mechanical timer and a starter operably connected to supply the spring with strain energy. The spring releases the strain energy accumulated in it to drive the valve switching device, and the mechanical timer consumes a part of the strain energy released from the spring to regulate duration of the operation of the spring.

Abstract: A flush toilet comprises a toilet body, a first means for supplying wash water, a second means for discharging wash water, a third means for operating as a valve disposed between the first means and the second means, a fourth means for switching the third means, a fifth means for driving the fourth means, a mechanical timer and a sixth means for being manipulated to supply the fifth means with strain energy. The fifth means releases the strain energy accumulated in it to drive the fourth means, and the mechanical timer consumes a part of the strain energy released from the fifth means to regulate duration of the operation of the fifth means.
