Изобретение относитс к машиностроению , а именно к двигателестроению, конкретнее к поршн м двигателей внутреннего сгорани с термостойким покрытием на камере сгорани .The invention relates to mechanical engineering, in particular to engine-building, more specifically to pistons of internal combustion engines with a heat-resistant coating on the combustion chamber.
Известен поршень дл двигател внутреннего сгорани с камерой сгорани типа Гессельмана, содержаший термозащитную накладку выполненную в виде центрального диска, закрепленного в корпусе поршн 1.A well-known piston for an internal combustion engine with a combustion chamber of the Hesselman type, containing a thermal overlay made in the form of a central disk fixed in the housing of the piston 1.
Недостатком известной конструкции вл етс то, что накладки с камерой сгорани типа Гессельмана сложны в изготовлении и не обеспечивают в достаточной мере защиту днища поршн от термических нагрузок.A disadvantage of the known construction is that the linings with the Hesselman-type combustion chamber are difficult to manufacture and do not sufficiently protect the piston head from thermal loads.
Целью изобретени вл етс повышение надежности работы поршн .The aim of the invention is to increase the reliability of the piston.
Поставленна цель достигаетс тем, что поршень содержит дополнительную термозащитную накладку в виде разжимного кольца , установленного по периферии камеры сгорани . Кроме того, центральный диск снабжен сплошным кольцевым выступом со стороны камеры сгорани .The goal is achieved by the fact that the piston contains an additional thermal barrier in the form of an expanding ring mounted on the periphery of the combustion chamber. In addition, the central disk is provided with a continuous annular protrusion from the side of the combustion chamber.
На чертеже схематически показана предлагаема конструкци поршн .The figure shows schematically the proposed piston design.
Поршень 1 с камерой сгорани типа Гессельмана имеет термозащитную накладку , выполненную в виде центрального 5 диска 2, закрепленного в корпусе поршн при помощи болта 3 с упругой шайбой 4, и дополнительную термозащитную накладку выполненную в виде разжимного кольца 5 и установленного по периферии каме ,Q ры сгорани . Дл креплени дополнительной накладки используютс фигурные планки 6 и винты 7. Центральный диск 2 со стороны камеры сгорани имеет сплошной кольцевой выступ 8.Piston 1 with a Hesselman-type combustion chamber has a thermal protective lining made in the form of a central 5 disc 2 fixed in the piston housing with a bolt 3 with an elastic washer 4 and an additional thermal protective lining made in the form of an expanding ring 5 and mounted on the periphery of the cam, Q ry burnout To fasten the additional lining, figured straps 6 and screws 7 are used. The central disk 2 on the side of the combustion chamber has a continuous annular protrusion 8.
При работе двигател внутреннего сго15 рани , разделенные накладки, равномерноWhen the engine is operating, the internal engine is divided evenly apart.
