    • An assembly includes an oil pump body connected with the crankcase, and has a passageway with an outlet portion communicating with a reservoir. A pinion gear is positioned in the oil pump body, connected with the drive shaft for rotation therewith, and mates with an idler gear. A first drive gear is mounted on a first camshaft and mates with the idler gear. A second drive gear is mounted on the first camshaft in a spaced relationship with the first drive gear. A third drive gear is mounted on a second camshaft and mates with the second drive gear. A return gear has a first portion extending into the sump to draw oil, and a second portion mating with the idler gear adjacent the outlet portion of the passageway, such that oil drawn from the sump by the return gear flows from the sump through the passageway into the reservoir.
    • 组件包括与曲轴箱连接的油泵体,并且具有通道,其具有与储存器连通的出口部分。 小齿轮定位在油泵体中,与驱动轴连接以与其一起旋转,并与空转齿轮配合。 第一驱动齿轮安装在第一凸轮轴上并与空转齿轮配合。 第二驱动齿轮以与第一驱动齿轮间隔开的关系安装在第一凸轮轴上。 第三驱动齿轮安装在第二凸轮轴上并与第二驱动齿轮配合。 返回齿轮具有延伸到贮槽中的第一部分以抽出油,以及与邻近通道的出口部分的空转齿轮配合的第二部分,使得由回流齿轮从油底壳抽出的油从油槽流过通道 进入水库。
