PURPOSE: A device for producing hydraulic rotary force using repulsive force of a spring is provided to effectively produce rotary power without environmental pollution and a heavy economic burden. CONSTITUTION: A thread part(3-1) of a fixed shaft(3) is fit into a thread hole(1-3) formed to the left side of a housing body(1), and a rotating shaft(6) having a flange(6-1) is fit into a through hole formed to the right side. A driving body(2) having seat units(2-1,2-1a) is installed inside the housing body. A cylinder housing is coupled at the front end of a cylinder(2-3) formed to the left side of the driving body and a first hydraulic cylinder chamber(4a) is formed at the inner front end. A piston is fit to the first hydraulic cylinder chamber. A second hydraulic cylinder chamber(7a) having a piston(7) and a restoring spring(8) inside is formed at the outer end of a cylinder(2-3a) formed to the right side of the driving body. A flange (6-1) of the rotating shaft is coupled to the second hydraulic cylinder chamber. The first and second hydraulic cylinder chambers are communicated through a first passage(2-4). The first passage and a second passage(2-4a) installed in the seat units are interlocked. Pistons are installed to the right and left side of the inside of third hydraulic cylinder chambers formed at the inner end of the second passage. Long rotors and short rotors contacted with the pistons are installed to a long shaft bolt. |
