Abstract

Изобретение позвол ет повысить надежность двигател  путем улучшени  противозадирных свойств сопр жени  юбка поршн  - гильза. Дл  этого нижн   выемка 6 выполнена на нижнем торце юбки 2 и открыта в сторону торца , а верхн   выемка 5 расположена между дренажными отверсти ми 4 и масл ными карманами 3 касательно нижним кромкам отверстий 4. Такое выполнение кольцевых выемок обеспечивает попадание в них излишков масла, к-рое уменьшает трение между гильзой и юбкой . 3 ил. ,1 $ СЛThe invention makes it possible to increase the reliability of the engine by improving the anti-seize properties of the mating piston-sleeve liner. For this, the lower recess 6 is made at the lower end of the skirt 2 and is open towards the end, and the upper recess 5 is located between the drainage holes 4 and the oil pockets 3 regarding the lower edges of the holes 4. Such a design of the annular recesses ensures that excess oil gets into them, The second reduces friction between the sleeve and the skirt. 3 il. , $ 1 SL
