油圧式工具の出力切換え機構。 A large cylinder formed in the body includes an oil tank attached to the body, a pump mechanism that sucks hydraulic oil from the oil tank and pumps it under pressure, and a small cylinder chamber that receives the pressure oil from the pump mechanism. In a hydraulic tool comprising an output piston that slides within a cylinder chamber, pressurized oil from the pump mechanism is supplied to the body into the large cylinder chamber at the base of the output piston via a switching valve that is manually opened and closed. An output switching mechanism for a hydraulic tool characterized by having an internal flow path for feeding.
