摘要： A casing for the lubrication of a camshaft of an internal combustion engine for automotive vehicles is partially filled with lubricating oil to effect splash lubrication of cams carried by the camshaft and has at least one lateral overflow port to maintain the oil at a substantially constant level. The overflow port is configured so as to prevent removal of oil which is not in excess of the required amount as a result of the shifting of the oil due to a uphill or downhill inclination of the vehicle. According to a preferred embodiment, the overflow port has a horizontal lower wall which corresponds to the desired maximum level of oil when the vehicle is level and this lower wall is flanked by inclined walls which correspond to the desired maximum level when the vehicle is in uphill and downhill orientations, respectively. More particularly, the preferred overflow port embodiment has a trapezoidal configuration which flares toward a side of a casing facing the camshaft and merges into a cylindrical configuration.

摘要翻译： 用于汽车用内燃机的凸轮轴的润滑的壳体部分地填充有润滑油，以实现由凸轮轴承载的凸轮的飞溅润滑，并且具有至少一个侧向溢流口以将油保持在基本上恒定的水平。 溢流口被构造为防止由于车辆的上坡或下坡倾斜引起的油的偏移而不超过所需量的油的去除。 根据优选实施例，溢流口具有水平的下壁，其在车辆平整时对应于期望的最大油位，并且该下壁在车辆处于上坡时对应于对应于期望最大水平的倾斜壁 和下坡方向。 更具体地，优选的溢流口实施例具有朝着朝向凸轮轴的壳体的一侧向外扩张的梯形构造并且合并成圆柱形构造。
