PURPOSE:To produce strong motive power with low power loss, by disposing a plurality of cylinder in series to each other, producing differentail thrust based on the difference of pressure receiving area of pistons by urging or pushing the piston faces of the cylinders, and circulating a constant amount of work fluid through the cylinders. CONSTITUTION:A plurality of cylinders 7, 8, 9, 10 have an equal capacity, but only an auxiliary cylinder 10 has a smaller pressure receiving area than other cylinders. When a coil 2 is excited, oil is supplied from a booster 1 to cylinders 7, 10. The cylinder 7 pushes the outer case of the cylinder 8, which in turn pushes a piston shaft of the cylinder 9, so that fluid in the cylinder 9 is forced into the cylinder 8 and the piston shaft of the cylinder 8 causes movement. Resultantly, a crank shaft 15 is turned. On the other hand, when another coil 3 is excited, the crank shaft 15 is turned in reverse direction by the similar cylinder mechanism (not shown in the drawing). |
