Abstract

Изобретение относитс  к двигателестроению. Целью изобретени   вл етс  повышение надежности и экономии масла. Маслосъемное поршневое кольцо состоит из маслосъемного элемента из стального проката, имеющего два элемента, соединенных перемычкой, в которой выполнены маслоотвод щие прорези 10, и расширител . Большие оси маслоотвод щих прорезей 10 расположены под углом α = 50 - 60° к элементам маслосъемного кольца, при этом шаг между большими ос ми маслоотвод щих прорезей L = 2,2 HCTGΑ, а минимальное рассто ние между смежными прорез ми равно ширине прорези, где H - высота перемычкиFIELD: engine building. The aim of the invention is to increase the reliability and economy of oil. An oil scraper piston ring consists of an oil scraper element from rolled steel having two elements connected by a jumper, in which oil discharge slots 10 are made, and an expander. The major axes of the oil diverting slots 10 are located at an angle α = 50 - 60 ° to the elements of the oil scraper ring, with the spacing between the large axes of the oil diverting slots L = 2.2 HCTGΑ, and the minimum distance between adjacent slots is equal to the width of the slot, where H - jumper height

L - шаг между большими ос ми прорезей. 5 ил.L is the pitch between the major axes of the slits. 5 il.
