Abstract
PURPOSE: To take off power only with the open-close operation of valves, by dividing a vessel into two spaces and mounting the valves, a water drain pipe, piston and spring to the vessel.
CONSTITUTION: A vessel 1 is divided into two spaces 8, 9 to which valves 5, 6, 7 water drain pipe 2, piston 3 and spring 4 are mounted. If water is filled in the vessel 1 to open the valve 5, the spring 4 is contracted by the pressure of the water to raise the piston 4. Then if the valve 5 is closed and the valve 6 is opened, the spring 4 is extended to lower the piston 4. At this time, air goes into the space 9 to drain water in the space 9 from the water drain pipe 2 and lower the level of water in the space 9. And if the valve 7 is opened in a state with the valves 6, 5 as closed, the level of water in the vessel 1 reverts to the former condition. In this way, only the open- close operation of the valves 5, 6, 7 can take off power.
