Title:
SINGLE ROD DOUBLE ACTING HYDRAULIC CYLINDER
Document Type and Number:
Japanese Patent JPS5846207
Kind Code:
A
Abstract:
PURPOSE:To enable to vary a ratio between thrust and tension of a piston rod freely, by making a play fit of a floating piston in a hydraulic cylinder separately from a piston provided on a piston rod sliding inside the hydraulic cylinder. CONSTITUTION:A piston rod 7 having a passive part 8 of a piston fitted in a cylinder 1 slideably is fitted with a floating piston 2 by keeping a play separately from the passive part 8 of the piston. Then, although when the piston rod 7 is pulled toward the left for driving hydraulic oil led into a hydraulic oil chamber 4 is acted to an area of pi/4(D<2>-d<2>) for transference, tension of the piston rod 7 for identical hydraulic pressure can be varied variously by a method wherein several sizes of rods are provided as diameters d of the rods 7, which are used by combining with the floating piston 2 having different sizes of center hole diameters.
