    • An automotive engine oil pump assembly having first and second pump mechanisms contained within a common housing. A shaft rotatably supported in the housing drives the pump mechanisms in a conventional manner. The pump mechanisms are offset in phase to reduce flow pulsations through the housing and limit pump noise and vibration. The first pump mechanism communicates with a common inlet and first outlet of the housing. The second pump mechanism communicates with the common inlet and second outlet of the housing. A common reservoir connected to inlets of the first and second oil pump mechanisms provides a supplemental oil source to balance oil pressures at the pump inlets to prevent pump cavitation and further reduce pump noise and vibration.
    • 一种具有包含在公共壳体内的第一和第二泵机构的汽车发动机油泵组件。 可旋转地支撑在壳体中的轴以常规方式驱动泵机构。 泵机构相位偏移以减少通过壳体的流量脉动,并限制泵的噪声和振动。 第一泵机构与壳体的公共入口和第一出口连通。 第二泵机构与壳体的公共入口和第二出口连通。 连接到第一和第二油泵机构的入口的公共储存器提供补充油源以平衡泵入口处的油压,以防止泵空化,并进一步减少泵噪声和振动。

    • A metal strip casting apparatus and a method of casting continuous metal strip includes assembling a pair of counter-rotatable casting rolls having casting surfaces positioned laterally forming a nip between for casting, and delivering molten metal through a delivery nozzle disposed above the nip capable to form a casting pool supported on the casting rolls. The delivery nozzle comprises segments each having elongate nozzle body with longitudinally extending side walls, end walls and a bottom part to form an inner trough, a nozzle insert disposed above bottom portions of the inner trough of each segment and supported relative to the nozzle body through which incoming molten metal may be delivered to the inner trough of each segment of the delivery nozzle, and the elongate nozzle body of each segment having passageways in fluid communication with the inner trough and outlet openings capable of discharging molten metal from the nozzle body outwardly into the casting pool.
    • 金属带铸造装置和铸造连续金属条的方法包括组装一对可逆转铸造辊,其具有横向形成用于铸造的辊隙的铸造表面,并且通过设置在能够形成的辊隙之上的输送喷嘴输送熔融金属 支撑在铸辊上的铸池。 输送喷嘴包括各自具有细长喷嘴体的段,其具有纵向延伸的侧壁,端壁和底部部分以形成内槽,喷嘴插入件设置在每个段的内槽的底部上方并相对于喷嘴体通过 输入的熔融金属可以被输送到输送喷嘴的每个段的内槽,并且每个段的细长喷嘴体具有与能够从喷嘴体向外排出熔融金属的内槽和出口开口流体连通的通道, 铸造池。
