ABSTRACT:
A magnetic cylinder has at least one magnet unit on the movable side and at least one magnet unit on the stationary side. Each unit on any such side consists of a plurality of magnets as are set to result in the positive and negative magnetic poles to alternate equiangularly in the peripheral direction of the cylinder. A piston rod and a maneuvering mechanism are operatively connected to the at least one magnet unit on the movable side in such a manner that the at least one magnet unit on the movable side may be rotationally rocked by means of the maneuvering mechanism so that by the thusly shifted attracting or repelling action between both the said magnet units the piston rod is caused to reciprocatingly move to and for in the axial direction of the cylinder.
