Abstract

PURPOSE: To apply a certain and strong initial driving force to a piston rod by arranging magnets on the piston rod side, projecting in the repulsive direction from the opposite magnets on the cylinder side.
CONSTITUTION: When a coil 17 is brought into conduction in the state where the magnets 1 and 4 shown in the figure are attracting with each reverse magnetic pole, the magnetic body 16 and a holding member 18 rotate in integrated form, and a transmission shaft 8 is turned by a fixed angle (90 degree), and the magnets 1 and 4 are magnetized to the same magnetism, and the magnets 1' and 4 are magnetized reversely. Then, a repulsive force acts between the magnets 1 and 4, and an attracting force acts between the magnets 1' and 4, and a piston rod 3 is protruded toward the cover 7 side and shifted, and operates in extension. In contracting operation of the cylinder, the transmission shaft 8 is reversely returned, or rotated in the direction and by the angle described the above. As, in this magnetic cylinder, the magnet 4 is positioned, protruding in the repulsive direction from the opposite magnets 1 and 1' in the operation described the above, strong initial driving force can be obtained certainly.
