<p>PURPOSE:To prevent blinding by providing constitution in such a way as utilizing relatively reciprocating force of a piston for opening and closing a valve, provided below the piston, so as to remove foreign matters in a cylinder, in the case of a device for performing a water feed, pumping up, power generation, etc., by means of reciprocating motion of the piston. CONSTITUTION:In the case of a wave power pump, a piston rod 9 and a piston 8 are moved downward with a float 1 through a chain 12, and in a process before a stopper 10 is adapted to a boss 14, a catch pin 21 touches the boss, so that a valve 17 and a pin 19 are relatively moved rotating an arm 18, provided in the valve 17, opening the valve 17. Next by the float 1, when the piston rod 9 and the piston 8 are moved upward, water in a cylinder 6 is jetted from an opening of the valve 17, and foreign matters of drain, sand, etc., accumulated in a boots 15, is jetted. When the piston rod 9 is lifted to its original position, the valve 17 is closed through the arm 18, thereafter the piston 8 rises in a closed condition of the valve 17, thus exhibiting its water delivering action.</p> |
