Abstract: A mold package for forming a cast device such as an engine block is described. The mold package includes a profiled chill and a mold core assembly that is disposed on the profiled chill. The mold core assembly defines a plurality of bulkheads of the engine block. The profiled chill includes a first chill portion having a second chill portion and a plurality of third chill portions arranged thereon, wherein the second chill portion is a semicylindrical element. The third chill portions are arranged to be adjacent to the plurality of bulkheads of the engine block.

Abstract: A packaged vacuum pump and oil pump for use in a vehicle generally includes an oil pump module and a vacuum pump module. The oil pump module is configured to circulate oil, and is fitted to a first drive shaft configured to transmit torque to the oil pump module. The vacuum pump module is configured to generate a vacuum, and is fitted to a second drive shaft configured to transmit torque to the vacuum pump module. The packaged vacuum pump and oil pump also includes a clutch. The clutch connects the first drive shaft and the second drive shaft, and is configured to transfer torque from the first drive shaft to the second drive shaft when the clutch is engaged. The clutch may be a hydraulic clutch configured to receive a pressurized fluid, which may be oil received from the oil pump module, to engage the clutch.

Abstract translation: 用于车辆的包装真空泵和油泵通常包括油泵模块和真空泵模块。 油泵模块被配置为循环油，并且被配置到构造成将扭矩传递到油泵模块的第一驱动轴上。 真空泵模块被配置为产生真空，并且被配置到构造成将扭矩传递到真空泵模块的第二驱动轴。 包装的真空泵和油泵也包括离合器。 离合器连接第一驱动轴和第二驱动轴，并且构造成当离合器接合时将扭矩从第一驱动轴传递到第二驱动轴。 离合器可以是被配置为接收加压流体的液压离合器，加压流体可以是从油泵模块接收的油以接合离合器。
