ヨベルの旋回駐車ブレーキ用油圧回路。 In a hydraulic circuit for a swing parking brake that applies a brake to the swing shaft of the swing motor and releases the brake by applying a pilot pressure signal from a pilot pump to the brake mechanism, the drain port of the swing motor and the brake in the brake mechanism are connected to each other. The drain port of the swing motor is connected to the oil tank via an oil path through the brake chamber in the brake mechanism, and the drain port of the swing motor is connected to the oil tank via a resistance valve from the oil path on the drain port side of the swing motor. A hydraulic circuit for a swing parking brake of a hydraulic excavator, characterized in that it can be connected to a hydraulic excavator.
