    • This invention relates to an internal combustion engine including an oil seal ring between a cylinder block and a crank shaft, a crank shaft cap and a conduit. The cylinder block includes a plurality of cylinders, a crank shaft support portion and an oil seal retainer. The crank shaft support portion is located under the plurality of cylinders and the oil seal retainer projects outwardly from the cylinder block. A crank case is defined within the cylinder block. The crank shaft cap is secured to the crank shaft support portion and an opening is defined therebetween. The crank shaft includes a main journal and a flange portion. The main journal is inserted into the opening defined between the crank shaft support portion and the crank shaft cap. The crank shaft is rotatably mounted on both the cylinder block and the crank shaft cap. The flange portion extends outwardly from the main journal and is spaced from the crank shaft support portion and the oil seal retainer of the cylinder block, so that a cavity is defined between the flange portion of the crank shaft, the oil seal retainer, the crank shaft support portion of the cylinder block and the crank shaft cap. The oil seal ring is located between the oil seal retainer of the cylinder block and the outer peripheral surface of the flange portion. The conduit is defined within the crank shaft support portion or the crank shaft cap. The conduit communicates the cavity with the crank case.
    • 本发明涉及一种内燃机,其包括在气缸体和曲轴之间的油封环,曲柄轴盖和导管。 气缸体包括多个气缸,曲轴支撑部分和油封保持器。 曲轴支撑部分位于多个气缸下方,油封保持器从气缸体向外突出。 曲轴箱定义在气缸体内。 曲柄轴盖固定在曲柄轴支撑部分上,并且在其之间限定开口。 曲轴包括主轴颈和凸缘部。 主轴颈插入到曲柄轴支撑部分和曲柄轴盖之间限定的开口中。 曲柄轴可旋转地安装在气缸体和曲柄轴盖上。 凸缘部分从主轴颈向外延伸并且与曲轴支撑部分和气缸体的油封保持器间隔开,从而在曲轴的凸缘部分,油封保持器,曲柄 气缸体的轴支撑部分和曲柄轴盖。 油封环位于气缸体的油封保持架和凸缘部的外周面之间。 导管限定在曲柄轴支撑部分或曲柄轴盖内。 导管将空腔与曲轴箱连通。
