Abstract: There are provided a synthetic resin joined body and a method of manufacturing the same, with which it is possible to secure both of sealing performance of a fluid passage and joint strength between synthetic resin parts, even if an area of a portion to be welded is reduced. The synthetic resin joined body includes: a baffle plate; an oil passage forming member which comes in contact with the baffle plate; an oil passage which is formed between the baffle plate and the oil passage forming member and through which lubricant flows; a sealing portion which is formed by welding the baffle plate and the oil passage forming member to each other on an outer side of the oil passage to seal a periphery of the oil passage; and a joint portion for joining the baffle plate and the oil passage forming member to each other.

Abstract: An oil sump is mounted on an assembly formed by a crankcase and a flywheel housing of an internal combustion engine. The flywheel housing has a first parting plane to the crankcase and to the oil sump. In mounted state, the joint faces of the flywheel housing, the crankcase, and the oil sump lie on each other. The crankcase has a second parting plane to the oil sump. In mounted state the joint faces of the crankcase and the oil sump lie on each other. At least one guide is provided between the flywheel housing and the oil sump, the guide orienting at least the joint faces of the oil sump and the crankcase relative to each other during connection of the oil sump to the assembly formed by the crankcase and flywheel housing, such that on creation of the abutment connection between the oil sump and the crankcase, these joint faces are oriented substantially planar parallel.

Abstract: A lubricant assembly that is configured as part of a lubricating system that flings, or slings, fluid lubricants about the interior of compressors. In one embodiment, the lubricant assembly includes a lubricant guide member with a body member that has a pair of peripheral side members with angled surfaces. The construction is amenable to more consistent fabrication constraints (e.g., tolerances), as well as to offer features that can improve operation of the lubricating system, e.g., as operative in the compressors. In use, the lubricant guide member is disposed transverse to a longitudinal axis of a shaft that is configured to rotate a slinger member to fling the lubricant. This configuration captures lubricant that falls downwardly from other parts of the compressors. The angled surfaces of the side members direct this captured lubricant toward the shaft, and other rotating components, of the lubricating system.

Abstract: Engine lubrication systems and methods of manufacturing and implementing engine lubrication systems and methods. In particular embodiments, an engine system includes an internal combustion engine lubrication system that utilizes a stacked configuration of a through-bolted engine to pattern around through-bolts and utilizes substantially hollow bulkheads to define a central high-pressure lubrication reservoir that minimizes lube system pressure while maintaining pressure at the extremities of the lubrication circuit. Available space is utilized within the bulkheads to provide a lubrication drainage restriction for reducing lubrication losses at engine shut-down.
