STORAGE PRESSURE PUMP TO AUTOMATICALLY OPEN/CLOSE SEALING INSIDE CYLINDER INTERLOCKING WITH VERTICAL MOVEMENT OF PISTON AND TO REPEATEDLY AND VERTICALLY MOVE PISTON FOR CONTINUOUSLY OPERATING FOR LONG TIME WITHOUT USING ELECTRIC POWER

摘要

PROBLEM TO BE SOLVED: To automatically, repeatedly and vertically move a piston without using electric power and manually stop the move of the piston if necessary and then start operation again in a storage pressure pump wherein a cylinder is installed at a water bottom. SOLUTION: Inside the cylinder 1 installed at the water bottom, sealing inside the cylinder 1 is automatically opened/closed interlocking with the vertical move of the piston 2 and the piston 2 is repeatedly and vertically moved for continuously operating the storage pressure pump for a long time. A sub sealed opening/closing conduit 13 is provided thereon other than a sealed opening/ closing conduit 9 and manually opened/closed by an operation control lever 14.
