特徴とするしゃ断器の流体圧操作装置。A damper piston integrated into a piston that fits into an operating cylinder and is driven by fluid pressure forms a damper chamber between a damper piston and a flange that closes one end of the operating cylinder at the end of the operating stroke of the piston. In the fluid pressure operating device, the flange is provided with a flow path that communicates the damper chamber with the cylinder inner chamber, and the valve body is always biased toward the chamber side and the valve body is provided with a throttle that communicates the two at all times. A fluid pressure operating device for a circuit breaker, characterized in that a perforated check valve is provided in the flow path.
