摘要： A multi-plate clutch system includes an outer clutch member having a plurality of first clutch plates thereon, a central spool having a plurality of second clutch plates thereon interspaced with the first clutch plates. The clutch system also includes a cam mechanism including a protruding cam and a recessed cam. The protruding cam and the recessed cam respectively include first inclined faces and second inclined faces, which are inclined in the same direction with respect to the circumferential direction. The protruding cam is thus brought into a point contact with the recessed cam during clutch engagement. As such, the multi-plate clutch system can maintain constant variable characteristics of the clutch capacity even when there is a variation in processing accuracy at the time of the production.

摘要： An internal combustion engine is provided with an internal piston cooling system that jets oil from an oil jet onto a surface of a piston during engine operation, to effectively cool the piston. In the piston cooling system of the internal combustion engine, each piston being arranged to reciprocate in a cylinder bore of a cylinder block, and oil is jetted from individual oil jets to each piston, respectively. An oil reservoir is formed in a crankcase journal wall, that journals a crankshaft of the engine. In the crankcase, oil supply passages are provided for supplying oil from a hydraulic supply source to the oil reservoir, and in turn, oil is operatively supplied from the oil reservoir to the oil jets via a passageway.
