Abstract
PURPOSE: To enable operating speed of several hundred meters/min. in a cylinder device for urgently operating a breaker in emergency and to provide response characteristics of several msec. to several ten order msec. of the time duration from the dispatch of an operation command to the completion of the operation in the cylinder device.
CONSTITUTION: The piston 2 can be telescoped within this cylinder device by means of a hydraulic accumulator as a fluid pressure source and a differential circuit of main valves 18, 23. Accordingly, the piston 2 can operate at high speed up to several hundred meters/min. of the operating velocity. Since poppet type valves of high flow gain are employed for the first and second main valves 18, 23 for telescoping th piston 2 and pilot valves 40, 45, respectively for controlling the main valves 18, 23, respectively, they can prevent fluid leakage from the respective sheet portions 17, 22 and improve the response characteristics, and, in addition, quickly move the piston 2 even during the time period from the dispatch of an operation command of the pilot valves 40, 45, for controlling separately the main valves 18, 23 to the completion of the operation up to several msec. to several ten order msec.
