Изобретение относитс к двигател м внутреннего сгорани .This invention relates to internal combustion engines.
Известны поршни дл двигател внутреннего сгорани , содержащие, по меньшей мере, два ручь , предназначенные дл поршневых колец, и наклонную маслоулавливающую канав {y на гребне между ними, служащую дл сбора масла, перемещающегос вдоль поверхности цилиндра при возвратно-поступательном движении поршневой группы 1. Указанна канавка.Pistons for an internal combustion engine are known that contain at least two strands for piston rings and an inclined oil catch channel {y on the crest between them, which serves to collect oil moving along the surface of the cylinder during reciprocating piston group 1. The indicated groove.

ра, исполн етс так, чтобы объем, отсекаемый кромкой канавки и прилегающий к ее верхнему торцу, был бы не меньше объема масла, пропущенного нижележащим кольцом за один ход поршн .Pa, is executed so that the volume, cut off by the edge of the groove and adjacent to its upper end, is not less than the volume of oil, passed by the underlying ring in one stroke of the piston.
Однако дл снижени расхода масла не менее важное значение, имеет и величина диаметров на гребне поршн поршневыми кольцами, где расположена канавка.However, in order to reduce oil consumption, the diameter value on the piston ridge of the piston rings, where the groove is located, is just as important.
Однако в таком поршне величины указанных диаметров над и под канавкой Выполнены практически одинаковыми , что резко снижает эффективность ее функционировани , поскольку отсутствуют реальные -преп тстви , ограничивающие перемещение масл ной пленки под действием сил инерции на всем участке между кольцами.However, in such a piston, the values of the indicated diameters above and below the groove are made almost the same, which drastically reduces the efficiency of its functioning, since there are no real obstacles that restrict the movement of the oil film under the action of inertial forces throughout the area between the rings.
Цель изобретени - снижение расхода масла в поршн х/ снабженных наклонной канавкой Беккера.The purpose of the invention is to reduce the oil consumption in the pistons x / fitted with an inclined Becker groove.
Это достигаетс путем задержани продвижени масл ной пленки на участке, лежащем выше канавки между This is achieved by delaying the advancement of the oil film in the area above the groove between
0 ней и маслосъемным кольцом, и осуществл етс за счет изменени величины диаметров участков гребн .It and the oil scraper ring, and is carried out by changing the value of the diameters of the ridge sections.
Дл этого диаметр гребна между маслоулавливающей канавкой и нижним For this, the diameter of the flange between the oil de-groove and the lower
5 ручьем выполнен мены11е диаметра поршн , в результате чего верхний участок гребн ограничивает перемещение масла вдоль цилиндра.5 the rim is made of piston diameter, as a result of which the upper part of the ridge limits the movement of oil along the cylinder.
На чертеже изображен предлагае0 мый поршень.The drawing shows the proposed piston.
Поршень 1 дл двигател внутреннего сгорани содержит, по меньшей мере, -два ручь 2 и 3 дл поршневых колец и наклонную под углом Ж Piston 1 for an internal combustion engine contains at least two creeks 2 and 3 for piston rings and inclined at an angle Ж
5 маслоулавливающую канавку 4 на гребне 5 между ними. Диаметр l участка 6 гребн 5 между маслоулавливающеП канавкой 4 и нижним ручьем 3 меньше диаметра D поршн 1, который в изображенном на чертеже варианте, рарсн5 oil catch groove 4 on the ridge 5 between them. The diameter l of the section 6 of the ridge 5 between the oil groove 4 of the groove 4 and the lower stream 3 is smaller than the diameter D of the piston 1, which in the variant shown in the drawing is rasn
