FLOAT DEVICE FOR DETECTING WATER LEVEL

摘要

PROBLEM TO BE SOLVED: To provide a float device which obtains an effect equivalent to or more than that of a larger float even when the float is small. SOLUTION: A rope 6 whose one end is fixed to the float 1 is suspended from a pulley 5 provided underwater, and is then turned up so that the other end is connected to an end of a rod 7 of a float valve. A weight 8 for assisting the buoyancy of the float 1 is mounted between the rod 7 and the pulley 5. COPYRIGHT: (C)2004,JPO
