チ液圧回路の液圧振動吸収補助装置。 Clutch fluid is interposed between a master cylinder and a damper-equipped slave cylinder in a hydraulic circuit that operates a vehicle's clutch mechanism, and absorbs hydraulic vibrations caused by the backflow of hydraulic fluid from the damper-equipped slave cylinder side when the clutch is connected. In a hydraulic vibration absorption auxiliary device for a pressure circuit, the inside of the cylinder is provided with an inlet hole for pressure fluid connected to piping on the master cylinder side at one end and an outlet hole connected to piping on the side of a slave cylinder with a damper at the other end. A cylindrical large-diameter piston valve having a partition wall is movable by being biased toward the outlet hole with a set load so as to allow the flow of the working fluid in the outlet hole by moving the valve toward the introduction hole. At the same time, the small diameter piston valve is moved into the large diameter piston valve toward the outlet hole so as to open and close the large diameter communication hole formed in the partition wall of the large diameter piston valve. The small-diameter piston valve is provided with a valve biased toward the large-diameter communication hole with a set load so as to allow the flow of hydraulic fluid through the large-diameter communication hole, and the small-diameter piston valve is provided with a valve that communicates with the large-diameter communication hole. A hydraulic vibration absorption auxiliary device for a clutch hydraulic circuit, characterized in that a small diameter communication hole is formed to constantly communicate the introduction hole side and the outlet hole side of the cylinder.
