Description

1
Изобретение относитс  к области двигателестроении и касаетс  поршней двигателей внутреннего сгорани .
Известны поршни двигателей внутреннего сгорани , содержащие камеру и вставку, закрепленную в ее днище.
Однако эти поршни не обладают достаточной надежностью вследствие высоких температурных напр жений.
Цель изобретени  - повышение надежности поршн .
Задача дл  достижени  поставленной цели состоит в использовании вставки дл  изменени  направлени  тепловых потоков в теле поршн .
Дл  этого в предложенном поршне вставку выполн ют в виде центрального стержн  и входной горловины, соединенной с последним ребрами и установленной в теле поршн  с зазором .
На чертеже изображен предложенный поршень .
Поршень 1 содержит камеру сгорани  2 и вставку 3, закрепленную в ее днище и выполненную в виде центрального стержн  4 и входной горловины 5, соединенной со стержнем 4 ребрами 6. Горловина установлена в теле поршн  1 с зазором 7. Ребра 6 могут быть выполнены с тангенциальным наклоном относительно оси стержн  4.
При работе двигател  внутреннего сгорани  тепловой поток направлен от горловины 5 через ребра 6 и вставку 3 в днище поршн . Наличие зазора 7 преп тствует проникновению тепловых потоков в зону уплотнительных поршневых колец поршн .
Предмет изобретени 
Поршень двигател  внутренного сгорани , содержащий камеру и вставку, закрепленную в ее днище, отличающийс  тем, что, с целью повыщени  надежности поршн , вставка выполнена в виде центрального стержн  и входной горловины, соединенной с этим стержнем ребрами и установленной в теле поршн  с зазором.
