を特徴とする液圧式さく岩槻の打妙機構。A piston having a small diameter portion at the front and rear is inserted into the cylinder to form a front hydraulic pressure chamber and a rear hydraulic pressure chamber, and the hydraulic pressure in the rear hydraulic pressure chamber is switched between high pressure and low pressure by a switching valve, and the piston is inserted into the cylinder. In the hydraulic type Iwatsuki impact mechanism, the hydraulic pressure passage for changing the piston stroke is provided with a stroke changing valve that can be operated by a pilot, and the stroke changing valve is operated. Iwatsuki's hydraulic drilling mechanism is characterized by a circuit that can be connected to remotely control the piston stroke.
