Title:
OIL FEED FOR CYLINDER
Document Type and Number:
Japanese Patent JPS6088276
Kind Code:
A
Abstract:
PURPOSE:To form the sufficient lubrication state over the all range and prevent wear-out by starting and completing oil feed during the time when the top ring of a piston is under an oil feeding hole, in the timely scraping-up for the lubrication of a cylinder. CONSTITUTION:In the timely scraping-up for the lubrication of a cylinder, oil feed is completed during the time when the top ring 11 of a piston 1 is under an oil feeding hole 12. In this case, the oil feeding groove on a cylinder liner is removed, and a ring equipped with a piston-ring slidable-surface oil groove 14 is adopted for the top ring 11 and other rings 13. Therefore, the sufficient lubrication state can be generated in the all range of the cylinder liner and the piston ring by combining the above-described three conditions. Therefore, the errosion wear-out of the cylinder liner is reduced, and the amount of the effective oil feed can be increased, and the amount of oil feed itselt can be reduced.
