Abstract: For a device for fracture separating bearing covers of aligned bearing bores in bearing arrangements of a machine member, which comprises a guided separating element which is profiled in an approximately semicircular shape and acts in the center onto a bearing cover in the bearing bore, for obtaining a device which is structurally simple, it is suggested that, for the fracture separating, a half-mandrel or full mandrel, which can be axially arranged in one or several bearing bores, is provided. An operating linkage, which only causes the guiding of the respective mandrel in the fracture separating direction, is applied to the respective mandrel transversely to its longitudinal course, the respective mandrel being held in a rotationally secured manner and each bearing cover being rotationally secured while being clamped against the respective mandrel.

Abstract: A cylinder block has a cylinder block body and a cylinder liner block mounted by casting in the cylinder block body. The cylinder liner block is formed from a material having a rigidity larger than that of the cylinder block body, and the cylinder liner block comprises a liner section mounted by casting in position in a cylinder barrel portion of the cylinder block body, and a reinforcing wall section mounted by casting in position in a bearing wall of a crank case portion of the cylinder block body. Thus, it is possible to increase the wear resistance of cylinders in the cylinder block, as well as to provide an increase in performance by reductions in vibration and noise of the engine including the cylinder block, and to provide reductions in size, weight and cost of the cylinder block by a reduction in thickness of the bearing walls.

Abstract: A refrigerant compressor for using HFC 134a as a refrigerant and a refrigerator oil such as polyether type oil, polyester type oil, or the like which is compatible thereto is disclosed. The refrigerant compressor has a iron type substrate with a compound layer mainly made of iron sulfide on sliding portions such as sliding parts and shaft in the compression mechanism. The sliding parts in the compression mechanism are a cylinder and a rotor and a piston which are moving parts. In a rotary type compressor, the sliding parts are a blade and so forth. The hardness of the compound layer mainly made of the aforementioned iron sulfide is large and thereby effectively preventing metals from being contacted and preventing adhesive abrasion which is the primary cause of the abrasion of the sliding portions. In addition, since the compound is stable in a moist situation, even if it is used along with polyether type oil, polyester type oil, or the like and HFC 134a, corrosion and abrasion due to dissolving of compound layer can be prevented.

Abstract: An improved crankcase structure for engine blocks and the like, may be fabricated wherein the crankcase is initially cast or otherwise formed with bearing caps integral therewith. The caps are preferably secured by severable connecting portions unidirectionally longitudinally adjacent their associated bearing receiving portions in the transverse webs of the cylinder block. The complete crankcase is then machined and the bearing caps are separated for subsequent assembly to the crankcase in conventional fashion. Consequently, the invention reduces the amount of tooling and machining time and equipment required for manufacturing crankcases for engine blocks and the like.

Abstract: An internal combustion engine comprises a cylinder block formed of aluminum alloy and having main bearing bulkheads each of which is formed with a bearing surface. Main bearing caps are securely connected respectively with the bearing bulkheads and formed of aluminum alloy. Each bearing cap is formed with a bearing surface which is located in opposition to the bearing surface of the bearing bulkhead. Additionally, the main journal of a crankshaft formed of iron alloy is rotatably disposed between the bearing surfaces of the bearing bulkhead and bearing cap. The surfaces of the crankshaft main journal is in direct contact with the bearing surfaces of the bearing bulkhead and bearing cap without using conventional bearing metals, thereby cutting off engine noise due to the existence of the bearing metals.

However, at critical points of the piston cycle, the fluid drains from the cavities due to the forces of gravity. An oil cooled piston (10) is provided which includes a fluid trap (50) adjacent the crown (18). Some of the cooling fluid is trapped as it drains and is retained to enhance cooling of the crown (18). The fluid trap (50) includes a slot (60) permitting a jet spray of lubricating oil to be directed past the trap (50) to the cavities adjacent the underside of the crown (18).
