Abstract
PURPOSE: To improve reliability of the device by providing lead switch and magnet, leaving a space in between, on the lever operated corresponding to the pressure in delivery pipe and opening and closing magnetic field of magnet by magnetism screening piece which moves corresponding to the pressure difference before and behind resistance valve.
CONSTITUTION: As pressure receiving diaphragm 8 is shifted downward by the force of spring 17 and lever 11 is turned reversely upward by the inner pressure reduction in delivery pipe 5 when faucet is opened, lead switch 13 and magnet 14 withdraw from screening piece 15 on differential pressure diaphragm 9 side to turn on lead switch 13 and start the operation of pump. When delivery force is raised by throttling faucet, pressure receiving diaphragm 8 shifts upward resisting spring 11 and lever 11 is turned reversely downward, but as differential pressure diaphragm 9 is kept being pushed down and magnetism screening plate 15 is receded from magnetic path of magnet 14, lead switch 13 is in ON condition. By doing so, reliability of the device can be improved.
