摘要： A lubrication system for a portable four-stroke engine includes an opening end of the breather passage is disposed at substantially a center of a valve-operating chamber, and the valve-operating chamber is formed by attaching a valve-operating chamber cover. An inner cover is attached to an inner surface of the valve-operating chamber cover so as to be provided along and in contact with the inner surface of the valve-operating chamber cover. A suction passage is formed as a gap between the circumferential edge of the top plate portion and the inner cover. Three or more suction tubes that are in communication with the suction passage are provided in the inner cover, each of the suction tubes having an opening end. At least one of the opening ends of the suction tubes is provided lower than the opening end of the breather passage in an attitude of the engine during use.

摘要： A lubrication apparatus for a four-stroke engine includes an oil tank, a supply passageway having an opening to supply oil mist from the oil tank to driving parts, the opening being provided in the oil tank. A partition is provided between the opening and a side wall of the oil tank, the partition being formed by partition plate members so as to divide an inside of the oil tank into an inner area and an outer area. The inner area includes the opening, and the outer area is defined between the inner area and the side wall. Oil can freely move between the inner area and the outer area, and the opening is placed in a position above a surface of the oil accumulated in the oil tank even when the four-stroke engine is tilted in every direction.
