Abstract
PURPOSE: To provide an oil scraper ring for being free from the increase in oil consumption caused by choking of a window and for being capable of shortening a manufacturing process, by making a sintered alloy made oil scraper piston ring whose window length is equal or nearly equal in a point of an inner and outer circumference.
CONSTITUTION: A pressured powder object of a sintered alloy made oil scraper piston ring, whose window length is equal or nearly equal in a point of an inner and outer circumference surface, and the one of a piston ring, which is divided into a upper and lower parts, are formed. The two pressured powder objects, between which a wax is nipped, are adhered closely to each other, and the work is sintered to make the sintered alloy made oil scraper piston ring. The method allows the window 4 of piston ring to be equal or almost equal in a point of the inner and outer circumerence, and thus, an excellent abrasion-proof property of the sintered alloy can be displayed.
