PURPOSE:To obtain driving energy, by utilizing the pressure of water feed. CONSTITUTION:A power production unit is provided upstream or downstream to a piston body 2. The power production unit comprises a water wheel 12 provided in a washing water passage, and an electricity generator coupled to the water wheel. When washing water is drained, it passes while rapidly rotating the water wheel 12, so that electric power is generated. The electric power is stored into a battery through a charging circuit so that the power can be used as driving energy for a sensor, a water feeder or the like. |
