摘要： A method of constructing a bedplate assembly for retention of a crankshaft in an internal combustion engine having an engine block includes forming a bedplate insert in a first pattern tool. The bedplate insert is defined by a height, a width, and a thickness. The bedplate insert also includes a shape having a variation in the width along the height. The method also includes arranging the formed bedplate insert in a second pattern tool. The method additionally includes forming in the second pattern tool a bedplate frame around the formed bedplate insert to generate the bedplate assembly. During forming of the bedplate frame, the variation in the width of the bedplate insert generates an internal rib in the bedplate frame that is configured to fix and retain the bedplate insert inside the bedplate frame and decrease deflection of the bedplate frame under crankshaft loads during operation of the engine.

摘要： A pump includes a housing defining an internal chamber having an axial inlet passage, a generally radial passage with an outlet to a volute. A rotatable impeller, disposed within the chamber, has a conical rear shroud sloping away from the axial inlet to define a rear recess. A shaft seal is disposed within the recess to minimize the axial length of the pump. A front surface of the shroud carries vanes operable to impel fluid from the axial inlet passage to the volute. Portions of the vanes extend forward into the axial inlet passage to induce coolant pre-rotation in the inlet passage and to improve pump efficiency. Pump efficiency may be further increased by a conical wall defining the axial inlet passage, a sloped wall defining the radial passage and a large radius between the axial inlet and the sloped wall to smooth fluid flow between the axial inlet passage and the volute.
摘要翻译：泵包括壳体，其限定具有轴向入口通道的内部腔室，大体径向通道，其具有出口到蜗壳。设置在腔室内的可旋转叶轮具有远离轴向入口倾斜的锥形后罩，以限定后凹部。轴密封件设置在凹槽内以最小化泵的轴向长度。护罩的前表面带有可操作的推动流体从轴向入口通道到蜗壳的流体。叶片的一部分向前延伸到轴向入口通道中以在入口通道中引起冷却剂预旋转并提高泵效率。通过限定轴向入口通道的锥形壁，限定径向通道的倾斜壁和轴向入口与倾斜壁之间的大半径，可以进一步提高泵的效率，以平滑流体在轴向入口通道和蜗壳之间流动。
