APPARAUS OF ENGINE BRAKE HAVING COMBINED OIL PASSAGE

摘要

PURPOSE: An oil-path integrated engine brake device is provided to facilitate the manufacturing of a locker shaft and an exhaust locker since an oil path is simplified due to the integration of oil paths and to reduce weight and cost since an actuator is integrated into a locker arm. CONSTITUTION: An oil-path integrated engine brake device comprises a locker shaft(100), a supply path(210), an exhaust locker arm(200), an actuator(300) and an oil control valve. The locker shaft forms an oil path, through which oil can flow. The supply path rotates on the locker shaft and connects the oil path to the outside. The exhaust locker arm comprises a space(220). The space is connected to the oil path and the bottom of the space is open. The actuator is located at the space and comprises a piston. The piston applies pressure to an exhaust valve when the pressure of the oil supplied to the supply path is over a given value. The oil control valve controls the pressure of the oil supplied to the supply path.
