Abstract

PURPOSE:To reduce cost by employing a double structure cylinder where a piston is contained in an inner cylinder, and feeding high pressure oil through an oil feed port communicated with an oil pressure source into the inner cylinder. CONSTITUTION:An inner cylinder 17 is arranged concentrically in an outer cylinder 11, and a piston 12 is contained slidably at the lower section of the inner cylinder 17. A lower header 15 forms a port 15b for delivering oil 6 in the inner cylinder 17. A port 13b for leading in pressurized gas is formed through an upper header 13. Since piston diameter can be reduced even if the volume of pressurized gas is made large enough for an output oil quantity, cost for accumulator can be reduced.
