Abstract

PURPOSE: To provide an apparatus for changing a brake oil, by a method wherein in an oil discharging piping line connected to a brake cylinder a control valve is provided that can slide in accordance with the flow resistance of the oil thereby after the flow-out of the oil containing air bubbles, the piping line is automatically cut off to completely automate the operation.
CONSTITUTION: In the oil discharging piping line 6 connected to the brake cylinder 4, a control valve 5 is provided that can slide according to the flow resistance of the oil. After the used oil in a brake circuit is completely drained by a pump 8, a change-over valve 20 is switched, a fresh oil is filled, and while the height of the liquid surface in an oil supply cup 18 is kept at a constant level by a level gage 21, a pedal 3 is repeatedly pushed through an air cylinder 22 to fill the brake circuit with the oil. The brake circuit is then filled with the fresh oil, and the oil containing bubbles overflows from a piping line 6 via a valve 5 and a bypass passage 6b. At this time while a movable valve 13 of the valve 5 does not abut on the valve seat 28 during the passage of the oil containing bubbles, upon the flowing of the oil containing no bubble, it abuts on the valve seat 28 to cut off the flow.
