Изобретение относитс  к машиностроению , а именно к двигателестрое- нию, и может быть применено в охлаждаемых поршн х двигателей внутреннего сгорани .The invention relates to mechanical engineering, namely engine building, and can be applied to cooled pistons of internal combustion engines.

Цель изобретени  - упрощение конструкции внутренней охлаждающей полости .The purpose of the invention is to simplify the design of the internal cooling cavity.

На чертеже показан поршень в сборе с шатуном.The drawing shows a piston assembly with a connecting rod.

Поршень содержит корпус 1 с кольцевой полостью 2 охлаждени , корпус 1 сочленен с верхей головкой 3 шатуна. Подвод щий канал 4 св зан с пальцевой полостью 2. Подающее отверстие 5 в головке 3 расположено соосно подвод щему каналу 4 при положении поршн  в верхней мертвой точке (БИТ),The piston comprises a housing 1 with an annular cooling cavity 2, the housing 1 is articulated with the upper head 3 of the connecting rod. The feed channel 4 is connected to the pin cavity 2. The feed hole 5 in the head 3 is located coaxially to the feed channel 4 when the piston is at the top dead center (BIT),

Поршень снабжен трубкой 6, один конец 7 которой размещен в канале 4, а другой конец 8 выполнен с косым срезом и расположен между головкой 3 шатуна и внзггренней поверхностью 9 корпуса 1, а подающее отверстие 5 расположено по оси 10 шатуна.The piston is equipped with a tube 6, one end 7 of which is placed in channel 4, and the other end 8 is made with an oblique cut and is located between the head 3 of the connecting rod and the outer surface 9 of the housing 1, and the feed hole 5 is located along the axis 10 of the connecting rod.

Поршень с каналом в виде трубки, соедин ющим внутреннюю охлаждающую полость с пространством под днищем поршн  в зоне отверсти  в верхней головке шатуна, при работе обеспечивает стабильнзда подачу масла, в верхнюю головку шатуна или в охлаждающую полость без дополнительного гидравлического сопротивлени .A piston with a tube-shaped channel connecting the internal cooling cavity to the space under the piston in the area of the hole in the upper head of the connecting rod ensures, during operation, oil supply to the upper head of the connecting rod or to the cooling cavity without additional hydraulic resistance.

Ввиду отсутстви  каналов под камерой сгорани  по вл етс  возмож834322 Due to the absence of channels under the combustion chamber, it appears possible. 834322

ность уменьшить толщину днища, что приводит к снижению веса поршн  и экономии его материала.This reduces the weight of the piston and saves its material.

Предлагаемый поршень имеет более простую конструкцию охлаждающей полости , что снижает трудоемкость ее .изготовлени , так как приводит к упрощению конфигурации стержн  дл  получени  внутренней охлаждающей 10 полости в литье, упрощает -процесс его изготовлени  и последующего удалени  из готовой отливки, а последнее уменьшает трудоемкость изготовлени  поршн  в целом.The proposed piston has a simpler design of the cooling cavity, which reduces the laboriousness of its production, as it simplifies the rod configuration to obtain an internal cooling cavity 10 in the casting, simplifies the process of its manufacture and subsequent removal from the finished casting, and the latter reduces the labor intensity of the production of the piston generally.
