Title:
DOUBLE ACTING HYDRAULIC CYLINDER
Document Type and Number:
Japanese Patent JP3721260
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a double acting hydraulic cylinder which can be miniaturized by simplifying its structure, and is extremely excellent in operability without any failures.
SOLUTION: In a double acting hydraulic cylinder to double-act a piston 6 by the change in hydraulic pressure in a first cylinder chamber 8 and a second cylinder chamber 9 formed in a cylinder body 2, a first supply system 11 to supply the oil to the first cylinder chamber 8 and a second supply system 12 to supply the oil to the second cylinder chamber 9 are provided, a first discharge system P to discharge the oil in the first cylinder chamber 8 and a second discharge system Q to discharge the oil in the second cylinder chamber 9 are provided, the first discharge system P and the second discharge system Q are controllable, and the piston 6 is double-acted by effecting the opening/closing operation of the first discharge system P and the second discharge system Q while supplying the oil from the first supply system 11 and the second supply system 12.
