Magnetic cylinder
First Claim
1. A piston assembly comprising:
- a slidably mounted piston rod;
a first magnetic unit mounted to said piston rod so as to be axially movable therewith, said magnetic unit including a plurality of segments of alternating polarity in the direction of rotation about the axis of said piston rod;
means for rotationally moving said first magnetic unit with respect to the axis of said piston rod; and
a second fixedly mounted magnetic unit, said second magnetic unit opposing said first magnetic unit and including a plurality of segments of alternating polarity in the direction of rotation about the axis of said piston rod, said first and second magnetic units disposed such that they will attract or repel each other, thereby causing linear movement of said piston rod, when said first magnetic unit is rotated into a selected position.

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.
