Device for varying a valve timing and lift for an internal combustion engine

摘要: A device for varying a valve timing and lift an internal combustion engine comprises first lifter second lifter, oil pressure chamber being defined between the lifter. The flow of from is continuously steplessly controlled through high-speed response control in extraction passage. While removed, does not lift. When closed, move together begins to By controlling action actuator valve, poppet can be optimum ones matching operating conditions.
