MAGNETIC FLUID PRESSURE CYLINDER

摘要

PROBLEM TO BE SOLVED: To provide a magnetic fluid pressure cylinder with its availability. SOLUTION: Fluid of fluid pressure is magnetic fluid and a piping to allow the magnetic fluid free to get in and out of the cylinder and a magnetic field generator to generate a magnetic field to set the inside of the piping in the magnetic field are provided on the fluid pressure cylinder having a piston to slide inside by receiving the fluid pressure and a rod fastened on the piston inside, an end part of which is projected outside and free to change projecting quantity by sliding of the piston.
