Abstract
Верхнее поршневое кольцо имеет прорезь, позволяющую кольцу расширяться с тем, чтобы, по существу, препятствовать прохождению газа камеры сгорания цилиндра через прорезь. Внешняя боковая поверхность кольца имеет по меньшей мере две канавки, простирающиеся от верхней стороны до нижней стороны кольца, чтобы дать хорошо ограниченный и регулируемый поток горячего газа из рабочей камеры к нижней стороне кольца. Канавки ограничивают падение давления через кольцо и, следовательно, износ кольца.
