摘要： PURPOSE: A hydraulic operation device is provided to achieve improved blocking performance with stability in a high speed continuous operation. CONSTITUTION: A hydraulic operation device is configured to provide a pressure to a high pressure operating fluid by a pressure accumulator device. The pressure accumulator device includes an injection pressure accumulator(13) and a blocking pressure accumulator(14) which are arranged independently from each other. The injection pressure accumulator and the blocking pressure accumulator include an injection pressure accumulating chamber(20) and a blocking pressure accumulating chamber(24) for inducing the high pressure operating fluid operating at both sides of an operating piston, an injection pressure accumulating piston(18) and a blocking pressure accumulator piston(22) disposed in the injection pressure accumulating chamber and the blocking pressure accumulating chamber, respectively, and an injection pressure provider unit and a blocking pressure provider for providing pressure to the high pressure operating fluid passed through the injection pressure accumulating piston and the blocking pressure accumulating piston and introduced into the injection pressure accumulating chamber and the blocking pressure accumulating chamber.
