。 A front chamber and a rear chamber are formed by a piston slidably provided within the cylinder body, and the front chamber and the rear chamber are connected to a hydraulic oil supply source via first and second hydraulic oil supply passages, An opening/closing valve that opens when the piston moves back by a predetermined amount is interposed in the second hydraulic oil supply passage, and when the piston is in the forward position, when a set pressure is applied from the hydraulic oil supply source to the front chamber, the piston moves back. The casing is provided in the first hydraulic oil supply passage of the rock drilling machine, and the inside of the casing includes a first chamber in which gas is sealed and a second chamber in which hydraulic oil flows in and out.
The second chamber is divided into two chambers by a diaphragm, a recess is formed near the outer periphery of the bottom surface of the second chamber, and an oil guide hole communicating with the first hydraulic oil supply passage is formed only in the recess. Machine accumulator.
