<P>PROBLEM TO BE SOLVED: To provide a water line pressure cylinder and a water line pressure cylinder device operated by boosting pressure of running water while using the running water as working fluid. <P>SOLUTION: Upper and lower concentric cylinders Ca, Cb are mounted at both sides of an upper rod cover 7, an upper rod Ra constituting the upper cylinder C1 is inserted into a sliding ring 26b of a lower rod packing 26 mounted on a packing insertion groove 16a of the upper rod cover 7, when the upper rod Ra is lowered, thus the running water in a water filling space W is sealed. A pressure of a lower rod Rb constituting the lower cylinder Cb is boosted and the lower rod Rb is projected by lowering the upper rod Ra while increasing the pressure of running water in the water filling space W. <P>COPYRIGHT: (C)2007,JPO&INPIT |
