FIELD: mechanical engineering; piston-type internal combustion engines, piston compressors and piston pumps. SUBSTANCE: piston ring lock has step at one end which is shifted relative to end surface of piston ring overlapping the expansion clearance to compensate for its increase due to wear of piston ring. EFFECT: enhanced efficiency.

Предлагаемое изобретение относится к машиностроению и может быть использовано в поршневых двигателях внутреннего сгорания, в поршневых компрессорах и в поршневых насосах. Сущность изобретения: в замке поршневого кольца, состоящем из ступеньки на одном конце кольца, ступенька смещена относительно торцевой поверхности поршневого кольца и выполнена перекрывающей температурный зазор по мере его увеличения при износе кольца.The present invention relates to mechanical engineering and can be used in reciprocating internal combustion engines, reciprocating compressors and piston pumps. The inventive lock of the piston ring, consisting of a step at one end of the ring, the step is offset from the end surface of the piston ring and is made to cover the temperature gap as it increases with wear of the ring.
